About 45.6 gAL are need to completely react with 135g FE2O3

To determine the mass of Al needed to react with 135 grams of Fe₂O₃, convert the mass of Fe₂O₃ to moles, use the stoichiometric ratio to find moles of Al needed, and then convert those moles to grams of Al to three significant figures.

The question is asking how many grams of aluminum (Al) are needed to completely react with 135 grams of iron(III) oxide (Fe2O3). This is a stoichiometry problem that requires using the balanced chemical equation:

Fe₂O₃(s) + 2Al(s) →2Fe(s) + Al₂O₃(s)

We start by converting the mass of Fe₂O₃ to moles using its molar mass:

1.0g Fe₂O₃ / 159.7 g/mol = moles of Fe₂O₃

Then we use the mole ratio from the balanced equation to convert from moles of Fe₂O₃ to moles of Al. The molar mass of Al is 27.0 g/mol. Finally, we convert moles of Al to grams using its molar mass to find the mass of Al needed for the reaction.

With the provided mass of 135g of Fe₂O₃, and the reaction stoichiometry, we can determine the mass of Al required which will be expressed to three significant figures.

Explanation:

Uranus is blue, not green; it has an atmosphere of hydrogen and helium, not methane.  While it does have an icy cold temperature, that's not a very unusual characteristic for an outer planet.  However, the tilt of the axis is unusual; no other planet is tilted almost completely on its side!

Answer:

The molar mass of copper (II) nitrate is 187.5 g/mol.

Explanation:

The molar mass is the mass of all the atoms in a molecule in grams per mole. To calculate the molar mass of a molecule, we first obtain the atomic weights from the individual elements in a periodic table. We then count the number of atoms and multiply it by the individual atomic masses.

Answer:

V₂ = 0.483L = 483mL

Explanation:

Given parameters:

Inital volume of air in shampoo bottle V₁ = 553mL

Original temperature of the bottle T₁ = 65°C

Final temperature T₂= 22°C

Final volume of the gas in the bottle V₂=?

We first take the given units into standard units:

K = T°C + 273

For T₁ we have the temperature to be = 65 + 273 = 338K

                 T₂ = 22 + 273 = 295K

For the volume we convert to Litres or dm³

              1000mL = 1L

V₁ = 553 x 10⁻³L = 0.553L

Now apply one of the gas laws to solve this problem.

From Charles law, we know that the volume of fixed mass of gas is directly proportional to its absolute temperature if the pressure is constant.

Charles's law is expressed as:

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

The unkown in the equation is V₂ we the express it as the subject of the formula :

                    V₂ = [tex]\frac{V_{1} T_{2} }{T_{1} }[/tex]

Putting the parameters in the equation gives:

                   V₂ = [tex]\frac{0.553 x 295}{338}[/tex]

                  V₂ = 0.483L = 483mL

An aerosol is a colloidal suspension in a gas, consisting of small particles or droplets that do not settle due to their small size. Examples include fog and smoke, where the dispersing medium is air. Understanding aerosols is important for their role in atmospheric processes and distinguishing them from other mixtures like solutions and suspensions.

An aerosol is a colloidal suspension in a gas. This means that an aerosol comprises tiny particles or droplets that are suspended within a gas. Unlike a suspension, where the particles can separate out over time due to their size (generally larger than 1 µm), the particles in a colloidal system, like an aerosol, do not settle because they are much smaller and range in size from about 2 to 500 nm. Aerosols can be composed of both solid and liquid particles dispersed in a gas, and these particles are stable enough not to settle quickly under the influence of gravity.

Examples of aerosols include fog, which consists of liquid water droplets dispersed in air, and smoke, which contains solid carbon particles also suspended in air. In both cases, the medium dispersing these particles is a gas (air), highlighting the defining characteristic of aerosols as a type of colloid. The significance of aerosols extends beyond simple examples, as they play integral roles in atmospheric processes, affecting weather, climate, and air quality, by influencing the scattering and absorption of radiation and serving as nuclei for cloud formation.

The ability of colloids, including aerosols, to scatter light, known as the Tyndall effect, further distinguishes them from solutions which are homogeneous mixtures and therefore do not exhibit this phenomenon. It's important to understand the distinction between aerosols and other types of mixtures, such as solutions and suspensions, to appreciate the unique physical and chemical behaviors of colloidal systems.

The actual answer is size and temperature

All stars are very hot. They resemble a gigantic furnace of atomic energy. Some stars are much hotter than others and appear to be brighter. The brightness of a star also depends upon its size and its distance from the Earth. Larger stars tend to be brighter, but a star closer to the Earth will appear brighter than one the same size that is farther away.

Acetone may be rinsed over materials to wash off explosive residue.

The real solution to the residue issue is to use methods that actually rinse away cleaner.

Some solvents and steam vapor systems are examples of residue-free chemistry. Completely water soluble and rinseable, soap-free products for carpet and hard floor care are a valuable part of the professional cleaner’s arsenal of residue-free cleaners.

In clean areas, all exposed surfaces should be smooth, impervious and unbroken in order to minimize the shedding or accumulation of particles or microorganisms and to permit the repeated application of cleaning agents, and disinfectants where used.

Acetone may be rinsed over materials to wash off the explosive residue. This can then be analyzed by x-ray techniques. Advance in explosives that has been proposed. Use of small color chips. These chips would be added to explosive materials available to the public.

Everything with mass has gravity

The answer is ionic

Answer: Option (a) is the correct answer.

Explanation:

A bond where transfer of electrons take place from one atom to another is known as an ionic bond.

An ionic solution is defined as a solution in which an ionic compound is dissociated into ions.

For example, NaCl is an ionic compound and when it is dissolved in water it dissociates as [tex]Na^{+}[/tex] and [tex]Cl^{-}[/tex] ions.

As it is known that electric current is the flow of charges. Hence, a solution that contains ions will be a good conductor of electricity.

Whereas in general, a covalent solution does not contain any ions.

Thus, we can conclude that ionic solutions are good conductors of electricity.

The force required to lift a rock at a vertical distance of 8 m if 80 j of work were done is 10 N.

A force is an effect that can alter an object's motion. Due to force, an object with mass can change its velocity, or accelerate.

Atoms that have different numbers of neutrons than protons and electrons are called isotopes.

Isotopes are atoms of the same element so they have the same number of protons. But, they have different mass numbers which means they have a different number of neutrons.

Answer:

Explanation:

At constant pressure and temperature, the mole ratio of the gases is equal to their volume ratio (a consequence of Avogadro's law).

Hence, the complete combustion reaction that has a ratio of 100 ml of gaseous hydrocarbon to 300 ml of oxygen, is that whose mole ratio is 1 mol hydrocarbon : 3 mol of oxygen.

Then, you must write the balanced chemical equations for the complete combustion of the four hydrocarbons in the list of choices, and conclude which has such mole ratio (1 mol hydrocarbon : 3 mol oxygen).

A complete combustion reaction of a hydrocarbon is the reaction with oxygen that produces CO₂ and H₂O, along with the release of heat and light.

Nuclear Fusion

Explanation:

This creates heat and protons that can heat up the sun

The core is composed of hot, dense plasma. The process nuclear fusion is responsible for the intense heat and pressure in the sun's core.

The process in which two lighter nuclei fuse together to form a heavier nucleus with the simultaneous release of a huge amount of energy is defined as the nuclear fusion.

Some mass is always lost during this process and this is converted into energy in accordance with Einstein's equation, E = mc². This huge amount of energy is released.

The fusion reactions are common in the interior of stars. The energy of our sun is believed to arise from a number of complex fusion steps. The net reaction is:

4 (₁¹H) → ₂⁴He + 2 (₊₁⁰e) + energy

During nuclear fusion in the core photons and neutrinos are released. These particles carry and emit the light, heat and energy of the sun.
