Answer:
The molecules align with the electric field
Explanation:
Polar molecules have dipoles (parts of the molecules have partial charges). This is because the atoms with a larger atomic mass attract more of the electron cloud of the molecule hence become partially electronegative. The other part of the molecule becomes partially positive. Therefore these parts of the molecule will align with opposite charges including in this case based on the charged metal plates. The positive dipole will align with the negative plate while the negative dipoles will align with the positive plate.
Answer:
The molecules align to the electric field.
Explanation:
A polar molecule is one that is neutral, that is, it does not have a net charge. But it has an internal distribution of charges that form a partially positive region and a partially negative region.
Coulomb's law indicates that charged bodies suffer a force of attraction or repulsion when approaching. The value of this force is proportional to the product of the value of its loads. The force is of attraction if the charges are of opposite sign and of repulsion if they are of the same sign. The force is inversely proportional to the square of the distance that separates them.
Then, following Coulomb's Law, the negatively charged end of the polar molecule will be attracted to the positively charged metal plate. And the positively charged end of the polar molecule is attracted to the negatively charged metal plate.
Then, the molecules align to the electric field.

Answer:
Option D is correct! - They have different masses.
Explanation:
Which aqueous solution has the highest boiling point at standard pressure?(1) 1.0 M KC1(aq) (3) 2.0 M KCl(aq)(2) 1.0 M CaC12(aq) (4) 2.0 M CaC12(aq)
Answer:
(4) 2.0 M CaCl₂(aq).
Explanation:
Adding solute to water elevates the boiling point.The elevation in boiling point (ΔTb) can be calculated using the relation:ΔTb = i.Kb.m,
where, ΔTb is the elevation in boiling point.
i is the van 't Hoff factor.
van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1.Kb is the molal elevation constant of water.
m is the molality of the solution.
(1) 1.0 M KCl(aq):
i for KCl = no. of particles produced when the substance is dissolved/no. of original particle = 2/1 = 2.
suppose molarity = molality, m = 1.0 m,
∴ ΔTb for (1.0 M KCl) = i.Kb.m = (2)(Kb)(1.0 m) = 2(Kb).
(2) 2.0 M KCl(aq):
i for KCl = no. of particles produced when the substance is dissolved/no. of original particle = 2/1 = 2.
suppose molarity = molality, m = 2.0 m,
∴ ΔTb for (1.0 M KCl) = i.Kb.m = (2)(Kb)(2.0 m) = 4(Kb).
(3) 1.0 M CaCl₂(aq):
i for CaCl₂ = no. of particles produced when the substance is dissolved/no. of original particle = 3/1 = 3.
suppose molarity = molality, m = 1.0 m,
∴ ΔTb for (1.0 M KCl) = i.Kb.m = (3)(Kb)(1.0 m) = 3(Kb).
(4) 2.0 M CaCl₂(aq):
i for CaCl₂ = no. of particles produced when the substance is dissolved/no. of original particle = 3/1 = 3.
suppose molarity = molality, m = 2.0 m,
∴ ΔTb for (1.0 M KCl) = i.Kb.m = (3)(Kb)(2.0 m) = 6(Kb).
So, the aqueous solution has the highest boiling point at standard pressure is: (4) 2.0 M CaCl₂(aq).
The aqueous solution with the highest boiling point at standard pressure is the 2.0 M CaCl2 solution because it has the highest concentration and dissociates into the most ions.
Explanation:The boiling point of an aqueous solution is influenced by the concentration of solutes due to the colligative property known as boiling point elevation. According to the principle of boiling point elevation, each mole of solute particles will raise the boiling point of 1 liter of water by 0.51°C. Taking this into account, the boiling point of a solution is also affected by the number of particles into which each formula unit dissociates in solution. For example, CaCl2 dissociates into three ions (one calcium ion and two chloride ions).
Given the options, the aqueous solution with the highest boiling point at standard pressure is the 2.0 M CaCl2 solution (Option 4). This is because it has the highest concentration of particles in solution: for every mole of CaCl2 there are three moles of ions due to dissociation, and its molarity is the highest among the given solutions.
Calculate the molarity of 48.0 mL of 6.00 M H2SO4 diluted to 0.250 L .
Answer:
1.152 M.
Explanation:
It is known that the no. of millimoles of a substance before dilution is equal to the no. of millimoles after dilution.∴ (MV) before dilution = (MV) after dilution
before dilution: M = 6.0 M, V = 48.0 mL.
after dilution: M = ??? M, V = 0.25 L = 250.0 mL.
∴ M after dilution = (MV) before dilution/(V) after dilution = (6.0 M)(48.0 mL)/(250.0 mL) = 1.152 M.
To calculate the molarity of the diluted solution, use the formula M1V1 = M2V2 and plug in the values to find the final molarity.
Explanation:To calculate the molarity of the diluted solution, we can use the formula:
M1V1 = M2V2
Where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.
Plugging in the values:
(6.00 M)(48.0 mL) = (M2)(0.250 L)
and solving for M2, we find:
M2 = (6.00 M)(48.0 mL) / (0.250 L) = 1152 M

Two unknown molecular compounds were being studied. A solution containing 5.00 g of compound A in 100. g of water froze at a lower temperature than a solution containing 5.00 g of compound B in 100. g of water. Which compound has the greater molar mass? Explain how you arrived at your answer.
Answer:
Compound B.
Explanation:
The freezing point depression is a colligative property. It depends on the number of particles (moles) present in the solution.
[tex]\Delta T_{\text{f}} = K_{\text{f}} b[/tex]
where b is the molal concentration
[tex]b = \dfrac{\text{moles of solute}}{\text{kilograms of solvent}}\\\\n = \dfrac{\text{mass}}{\text{molar mass}} = \dfrac{m}{M}[/tex]
If m is constant (5 g), then
[tex]n \propto \dfrac{1}{M}[/tex]
The compound with the greater molar mass has fewer moles and therefore fewer particles to depress the freezing point.
That must be Compound B, because Compound A has the lower freezing point.
Solute compound A caused a greater freezing point depression than compound B, suggesting that compound A has fewer particles in solution. Therefore, compound A must have the greater molar mass compared to compound B.
The question pertains to the concept of colligative properties, particularly, freezing point depression. Compound A, when dissolved in water, caused the freezing point to decrease more than compound B did under the same conditions. This behavior is explained by the colligative property of freezing point depression, which states that the freezing point of a solvent will decrease when a solute is dissolved in it.
The amount of freezing point depression is directly related to the number of solute particles in solution. Because both solutions contain the same mass of solute but compound A caused a larger freezing point depression, it must be that compound A has fewer particles in solution compared to compound B. Since fewer particles correspond to a larger molar mass, compound A has the greater molar mass.

300 moles of sodium nitrite are needed for a reaction. the solution is 0.450 m. how many ml are needed?
In order to provide the 300 moles of sodium nitrite required for the reaction using a 0.450 m solution, you would need 666,667 mL of the solution.
Explanation:To determine how many milliliters of a 0.450 m sodium nitrite solution are needed for a reaction where 300 moles of sodium nitrite are needed, you'll want to use the equation that relates moles, molarity (M), and volume (V). This equation is Moles = Molarity x Volume.
For the given question, we know the amount of moles (300 moles) and the molarity (0.450 m), so we can rearrange the equation and plug in our values to find the volume: Volume (L) = Moles / Molarity = 300 moles / 0.450 M = 666.67 L.
Do remember to convert this volume to milliliters because the question asks for the answer in milliliters. 666.67 L x 1000 mL/L= 666,667 mL.

To determine the volume of solution needed for the reaction, we can use the formula Volume = Number of moles / Molarity. In this case, the volume of solution needed is approximately 666,666.67 mL.
Explanation:To determine the volume of solution needed, we need to first calculate the number of moles of sodium nitrite in 300 moles. Since the solution is 0.450 M, this means there are 0.450 moles of sodium nitrite in every 1 liter of solution. Therefore, to calculate the volume of solution needed, we can use the formula:
Volume (in liters) = Number of moles / Molarity
Volume = 300 moles / 0.450 moles
To convert the volume from liters to milliliters, we can multiply the volume by 1000:
Volume (in milliliters) = Volume (in liters) * 1000
Plugging in the values, we get:
Volume (in milliliters) = (300 moles / 0.450 moles) * 1000 = 666666.67 mL
Therefore, approximately 666,666.67 mL of solution are needed for the reaction.

What are the two oxidation states of nitrogen in nh4no2?
Answer:
Oxidation state of N in (NH₄) is (-3).
Oxidation state of N in (NO₂) is (+3).
Explanation:
NH₄NO₂ is dissociated according to the equation:NH₄NO₂ → NH₄⁺ + NO₂⁻.
We can calculate the oxidation state:
NH₄⁺:
The total oxidation state of NH₄⁺ is (+1).
The oxidation state of H is known to be (+1).
∴ Oxidation state of N + 4(oxidation state of H) = +1.
∴ Oxidation state of N + 4(+1) = +1.
∴ Oxidation state of N = +1 - 4 = -3.
NO₂⁻:
The total oxidation state of NO₂⁻ is (-1).
The oxidation state of O is known to be (-2).
∴ Oxidation state of N + 2(oxidation state of O) = -1.
∴ Oxidation state of N + 2(-2) = -1.
∴ Oxidation state of N - 4 = -1.
∴ Oxidation state of N = -1 + 4 = +3.

Which would have a higher pH, a 0.1 M solution of a strong acid, or a weak acid? Why?
Answer:
1) Weak base.
2) Weak acid.
Explanation:
1) Which would have a lower pH, a 0.1 M solution of a strong base or a weak base? Why?
For bases:Solution with lower pH means that the solution has a lower basic character.
While solution with higher pH means that the solution has a higher basic character.
When we have a 0.1 M solution of a strong base or a weak base, the weak base will have a lower pH because it is not completely dissociated to produce OH⁻ ions.
While, strong base dissociates completely to produce OH⁻ ions, so it will has higher basic character and thus has a higher pH value.
So, weak base will have the lower pH value.
2) Which would have a higher pH, a 0.1 M solution of a strong acid, or a weak acid? Why?
For Acids:
Solution with lower pH means that the solution has a higher acidic character.
While solution with higher pH means that the solution has a lower acidic character.
When we have a 0.1 M solution of a strong acid or a weak acid, the weak acid will have a higher pH because it is not completely dissociated to produce H⁺ ions, so it has a lower acidic character.
While, strong acid dissociates completely to produce H⁺ ions, so it will has higher acidic character and thus has a lower pH value.
So, weak acid will have the higher pH value.

Given that Kw for water is 2.4× 10–14 at 37 °C, compute the pH of a neutral aqueous solution at 37 °C, which is the normal human body temperature.
Answer:
pH = 6.81.
Explanation:
The ionization of water is given by the equation :H₂O(l) ⇄ H⁺(aq) + OH⁻(aq),
The equilibrium constant (Kw) expression is:
Kw = [H⁺][OH⁻] = 2.4 x 10⁻¹⁴.
in pure water and neutral aqueous solution, [H⁺] = [OH⁻]
So, Kw = [H⁺]²
∴ 2.4 x 10⁻¹⁴ = [H⁺]²
∴ [H⁺] = 1.55 x 10⁻⁷ M.
∵ pH = - log [H⁺]
pH = - log (1.55 x 10⁻⁷) = 6.81.

Answer:
Ethanoic acid and 1-butanol can react to produce water and a compound classified as an ester.
Explanation:
Ethanoic acid reacts with ethanol in the presence of concentrated sulphuric acid as a catalyst to produce the ester "butyl ethanoate" and water:
CH₃COOH + CH₃CH₂CH₂CH₂OH → CH₃COOCH₂CH₂CH₂CH₃.
Ethanoic acid reacts with 1-butanol in an esterification reaction to produce butyl ethanoate and water. This is a common type of reaction in organic chemistry, resulting in the formation of an ester.
When ethanoic acid reacts with 1-butanol, a type of chemical reaction called esterification occurs. Esterification typically involves the reaction of a carboxylic acid (in this case, ethanoic acid) with an alcohol (here, 1-butanol) to form an ester and water. The specific ester formed from ethanoic acid and 1-butanol is called butyl ethanoate, and this is the compound classified as an ester mentioned in the question. The reaction can be summarized by the following equation:
CH₃COOH (ethanoic acid) + C₄H₉OH (1-butanol) →CH₃COOC₄H₉(butyl ethanoate) + H₂O (water)
This reaction typically requires an acid catalyst to proceed, commonly sulfuric acid or hydrochloric acid. The process of creating esters like butyl ethanoate is important in both organic chemistry and industry, where esters are used as fragrances, flavors, and solvents.
