2. At STP, how many liters of oxygen are required to react completely with 3.6 liters
of hydrogen to form water?
2H2(g) + O2(g)
2H20(g)

Answers

Answer:

1.8 L.

Explanation:

The balanced equation for the mentioned reaction is:

2H₂(g) + O₂(g) → 2H₂O(g),

It is clear that 2.0 moles of H₂ react with 1.0 mole of O₂ to produce 2.0 moles of H₂O.

At STP, 3.6 L of H₂ reacts with (?? L) of oxygen gas:

It is known that at STP: every 1.0 mol of any gas occupies 22.4 L.

using cross multiplication:

1.0 mol of H₂ represents → 22.4 L.

??? mol of H₂ represents → 3.6 L.

∴ 3.6 L of H₂ represents = (1.0 mol)(3.6 L)/(22.4 L) = 0.1607 mol.

To find the no. of moles of O₂ nneded to react completely with 3.6 liters (0.1607 mol) of hydrogen:

Using cross multiplication:

2.0 mol of H₂ react completely with → 1.0 mol of O₂, from stichiometry.

0.1607 mol of H₂ react completely with → ??? mol of O₂.

∴ The no. of moles of O₂ = (1.0 mol)(0.1607 mol)/(2.0 mol) = 0.08036 mol.

Again, using cross multiplication:

1.0 mol of O₂ represents → 22.4 L, at STP.

0.08036 mol of O₂ represents → ??? L.

∴ The no. of liters of O₂ will be produced = (0.08036 mol)(22.4 L)/(1.0 mol) = 1.8 L.

Answer:

The answer is 1.8 L

which statement is NOT true about the elements flourine, chlorine, and iodine?
a) they are all halogens
b) They react easily with metals
c) They are similar to noble gases
d) They are all nonmetals

Answers

They are all nonmetals

Answer:

The fluorine, iodine, and chlorine are c) They are similar to noble gases.

Explanation:

Nobel gas refers to those substances which doesn't have any vacant shell. They are completely filled. They are electron haters and are really hard to make them involve in chemical reaction. On the other hand, gases such as chlorine, bromine and iodine are called as halogens. They have ability to accommodate one electron in their valence shell as they have 7 already.

Thus, it can be inferred that gases such as chlorine, bromine and iodine are not similar to Nobel gas and thus the statement C which states they are similar to Nobel gas is considered as false.

In a certain variety of plants, red flowers appear in majority of plants and blue flowers appear only in a few plants. Which statement correctly describes the two traits? A. Both flower colors are dominant traits. B. Both flower colors are recessive traits. C. Red is a dominant trait and blue is a recessive trait. D. Red is a recessive trait and blue is a dominant trait.

Answers

Answer:

C

Explanation:

In the described scenario, red is a dominant trait which manifests more frequently in the plants, whereas blue is a recessive trait which appears less often. Hence, the correct option is C.

In a certain variety of plants where red flowers appear in the majority of plants and blue flowers appear only in a few, the correct description of the two traits would be that red is a dominant trait and blue is a recessive trait. This is because dominant traits are those that are expressed or visible in the organism when at least one dominant allele is present. Conversely, recessive traits require both alleles to be recessive in order to be expressed. Since red flowers are more common, it suggests that the red-flower trait is dominant over the blue-flower trait which is recessive and appears less frequently.

Hello!

The answer is:

The new volume is 2.84 L.

[tex]V_{2}=2.84L[/tex]

Why?

To solve the problem, we need to remember what STP means. STP means that the gas is at standard temperature and pressure, or 273.15 K (0°C) and 1 atm.

Also, we need to use the Combined Gas Law, since the temperature, the pressure and the volume are being changed.

The Combined Gas Law establishes a relationship between the temperature, the pressure and the volume of an ideal gas using , Gay-Lussac's Law, Charles's Law,  and Boyle's Law.

The law is defined by the following equation:

[tex]\frac{P_{1}V{1}}{T_{1}}=\frac{P_{2}V{2}}{T_{2}}[/tex]

Where,

[tex]P_{1}[/tex] is the first pressure.

[tex]V_{1}[/tex] is the first volume.

[tex]T_{1}[/tex] is the first temperature.

[tex]P_{2}[/tex] is the second pressure.

[tex]V_{2}[/tex] is the second volume.

[tex]T_{2}[/tex] is the second temperature.

So, we are given the following information:

[tex]V_{1}=2L\\P_{1}=1atm\\T_{1}=0\°C=273.15K\\P_{2}=80kPa=0.8atm\\T_{2}=37\°C=37+273=310K[/tex]

Then, isolating the new volume, and substituting, we have:

[tex]\frac{P_{1}V{1}}{T_{1}}=\frac{P_{2}V{2}}{T_{2}}\\\\V_{2}=\frac{P_{1}V{1}}{T_{1}}*\frac{T_{2}}{P_{2}}\\\\V_{2}=\frac{1atm*2L}{273.15K}*\frac{310K}{0.8kPa}=2.84L[/tex]

Hence, the new volume is 2.84 L.

[tex]V_{2}=2.84L[/tex]

How many moles of cesium xenon heptafloride can be produced from the reaction 12 mol cesium Floride with 14 mol xenon hexafloride

Answers

Answer:

12 moles of cesium xenon heptafluoride

Explanation:

The reaction of cesium fluoride with xenon hexafluoride is CeF + XeF6 -> CeXeF7 and the reaction is balanced as written. So the mole ratio is 1:1:1. We are given 12 moles of CeF and 14 moles of XeF6 are reacting, but after the 12 moles of CeF react completely, the reaction will stop as we have run out of one of our reactants. So only 12 moles of CeXeF7 will be produced.

Final answer:

12 moles of cesium xenon heptafluoride can be produced from the reaction of 12 mol cesium fluoride with 14 mol xenon hexafluoride, assuming a 1:1 molar ratio in the reaction and complete consumption of reactants.

Explanation:

To determine how many moles of cesium xenon heptafluoride (CsXeF₇) can be produced from 12 mol cesium fluoride (CsF) with 14 mol xenon hexafluoride (XeF₆), we first need to know the balanced chemical reaction. This reaction can be expressed as:

CsF + XeF₆ → CsXeF₇

If we assume 100% efficiency and that all reactants are used up completely, we would expect 12 moles of CsF to fully react with 12 moles of XeF6 since the reaction is in a 1:1 molar ratio. Therefore, the amount of product formed, CsXeF₇, would be 12 moles. The remaining 2 moles of XeF₆ will not react as there is no additional CsF to react with.

how much heat is required to raise the temperature of 1.248kg of gold from 22.0°c to 45.0°c(c=0.129j/g°c)​

Answers

Answer:

= 3,702.816 Joules

Explanation:

Heat absorbed by water is equivalent to heat released by copper.

Heat absorbed is given by:

Q = mcΔT

where m is the mass, c is the specific capacity and ΔT is the change in temperature.

Mass = 1248 g

ΔT = 45°C - 22°C = 23°C

c = 0.129j/g°c

Heat = 1248 g × 23°C × 0.129j/g°C

        = 3,702.816 Joules

Final answer:

The heat required can be calculated using the formula Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change.

Explanation:

The amount of heat required to raise the temperature of a substance can be calculated using the formula:

Q = mcΔT

Where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change. In this case, the mass of the gold is 1.248 kg, the specific heat capacity is 0.129 J/g°C, and the temperature change is from 22.0°C to 45.0°C. Converting the mass to grams (1.248 kg = 1248 g), we can calculate the heat energy:

Q = (1248 g)(0.129 J/g°C)(45.0°C - 22.0°C) = 19230.72 J

Therefore, the total amount of heat required to raise the temperature of 1.248 kg of gold from 22.0°C to 45.0°C is 19230.72 Joules.

Answer: 32 g/mol

Explanation:

According to Avogadro's law, 1 mole of every substance contains avogadro's number [tex](6.023\times 10^{23})[/tex] of particles and weighs equal to its molecular mass.

Diatomic molecule is a molecule formed by combination of two atoms of the same element. Example: [tex]O_2[/tex]

How much heat in kilojoules is evolved in converting 2.00 mol of steam at 150 ∘C to ice at -55.0 ∘C? The heat capacity of steam is 1.84 J/g∘C and that of ice is 2.09 J/g∘C.
Remember that if heat is leaving the system, then q is a negative number and if heat is entering the system, then q is a positive number.

Answers

Answer:

= 115.898 kJ

Explanation:

Heat evolved in converting 2.00 mol of steam at 150 ∘C to ice at -55.0 ∘C

Will be calculated in steps

Step 1; Heat evolved by steam from 150°C to 100°C

Heat = (2×18) g × 1.84 J/g°C × (150 -100)

       = 3312 Joules

Step 2; Heat required to convert steam to water without change in temperature;

Heat = moles × Molar Latent heat of vaporization.

        =  2 moles × 4.07 ✕ 104 J/mol

        = 8.14 × 10^4 Joules

Step 3: Heat evolved by water  from 100°C to 0°C.

Heat = mass × specific heat capacity × ΔT

        = (2 × 18) × 4.18 J/g°C × 100

        = 15,048 Joules

Step 4; Heat evolved in converting water at 0°C to ice at 0°

Heat = number of moles × molar latent heat of fusion

        = 2 moles × 6000 j/mole

        = 12 000 Joules

Step 5, heat evolved in converting ice at 0°C to -55°C

Heat = mass × specific heat capacity × ΔT

        = (2×18) × 2.09 j/g°C × 55

        = 4138.2 Joules

Total amount of heat evolved;

= 3312 J +  8.14 × 10^4 J + 15,048 J + 12 000 J +  4138.2 J

= 115,898.2 joules

= 115.898 kJ

Final answer:

To find the heat evolved in converting steam to ice, we need to consider the heat absorbed in three steps: heating the steam to 0°C, melting the ice, and finally cooling the water to -55.0°C. The heat evolved is approximately 235.92 kJ.

Explanation:

To find the heat evolved in converting steam to ice, we need to consider the heat absorbed in three steps: heating the steam to 0°C, melting the ice, and finally cooling the water to -55.0°C. We can calculate the heat absorbed in each step using the given heat capacities of steam and ice.

First, we calculate the heat absorbed in heating the steam from 150°C to 0°C. The formula for calculating heat is Q = mcΔT, where Q is the heat, m is the mass, c is the heat capacity, and ΔT is the change in temperature. 

The heat absorbed in heating the steam is Q = (2.00 mol)(18.02 g/mol)(1.84 J/g°C)(0 - 150°C) = -5,232.48 J. Since heat is leaving the system, the heat absorbed is a negative value.

Next, we calculate the heat absorbed in melting the ice at 0°C. The formula for calculating heat is Q = mL, where Q is the heat, m is the mass, and L is the heat of fusion. 

Using the given information, the heat absorbed in melting the ice is Q = (100 g)(2.09 J/g°C) = 209.0 J.

Finally, we calculate the heat absorbed in cooling the water from 0°C to -55.0°C. The formula for calculating heat is Q = mcΔT, where Q is the heat, m is the mass, c is the heat capacity, and ΔT is the change in temperature. 

The heat absorbed in cooling the water is Q = (100 g)(4.18 J/g°C)(-55.0 - 0°C) = -229,900 J. Since heat is leaving the system, the heat absorbed is a negative value.

To find the total heat absorbed in all three steps, we add the heats together: -5,232.48 J + 209.0 J - 229,900 J = -235,923.48 J.

To convert the heat from joules to kilojoules, we divide by 1000: -235,923.48 J / 1000 = -235.92 kJ.

Therefore, the heat evolved in converting 2.00 mol of steam at 150°C to ice at -55.0°C is approximately 235.92 kJ.

When 7.00 g of hydrogen react with 70.0 g of nitrogen, hydrogen is considered the limiting reactant because

7.5 mol of nitrogen would be needed to consume the available hydrogen.
hydrogen would produce 7.5 mol more ammonia than nitrogen.
nitrogen would produce 7.5 mol more ammonia than hydrogen.

Answers

Answer:

7.5 mol of hydrogen would be needed to consume the available nitrogen.

Explanation:

The balanced equation of the reaction of hydrogen with nitrogen is:

3H₂ + N₂ → 2NH₃

it is clear that 3mol of hydrogen react with 1 mol of Nitrogen to give 2 mol of ammonia.

firstly, we need to calculate the number of moles of both

for H₂:

number of moles = mass / molar mass = (7.00 g) /  (2.00 g/mol) = 3.5 mol.

for N₂:

number of moles = mass / molar mass = (70.00 g) /  (28.00 g/mol) = 2.5 mol.

using cross multiplication

1 mol of  N₂ needs → 3 mol of H₂

2.5 mol of  N₂ needs → ??? mol of H₂

∴ the number of mol of H₂ needed = (3*2.5) / 1 = 7.5 mol

So, the right choice is:

7.5 mol of hydrogen would be needed to consume the available nitrogen.

Answers

Answer:

Absolute zero is the lowest possible temperature of a gas.

Explanation:

Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. Absolute zero is the point at which the fundamental particles of nature have minimal vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion.By international agreement, absolute zero is defined as precisely; 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale; and –273.15 degrees Celsius on the Celsius scale.
Final answer:

Absolute zero is the lowest possible temperature, at which all molecular motion theoretically stops. Its actual implications, especially concerning the volume of a gas, don't fully comply with classical interpretations and delve into the realm of quantum physics.

Explanation:

Absolute zero is the lowest possible temperature at which all molecular motion ceases. It is defined as 0 on the Kelvin scale and equivalent to -273.15 degrees Celsius. This temperature is theoretically the point at which a gas would have no kinetic energy.

It's important to understand that while at temperatures near absolute zero, the behavior of real gases deviates from that predicted by ideal gas laws like Charles's Law or Amonton's Law. These deviations occur because the volume of the gas molecules themselves becomes appreciable relative to the total volume occupied by the gas and the collisions between the molecules can no longer be ignored.

However, these assumptions become less valid as temperatures approach absolute zero. The volume of a gas at absolute zero is a matter of quantum physics, and doesn't strictly comply with classical interpretations of gas behavior.
