The balanced chemical reaction is given as follows:

(NH₄)₃PO₄ (aq) + AI(NO₃)₃ (aq) → AIPO₄ (s) + 3NH₄NO₃ (aq)

A balanced chemical equation is one that has the same number of atoms of each type in the reaction on both the reactant and product sides. In a balanced chemical equation, both the mass and the change are equal.

The law of conservation of mass, which states that "the total mass of all the products of reaction in a chemical reaction equals the total mass of all the reactants," is satisfied by balancing chemical equations.

Thus, A solution of ammonium phosphate is mixed with a solution of aluminum nitrate. If aluminum phosphate is insoluble in water, its reaction is  (NH₄)₃PO₄ (aq) + AI(NO₃)₃ (aq) → AIPO₄ (s) + 3NH₄NO₃ (aq).

When acid is added to a solutions, it increases the H⁺ ion concentration in the solution. So the pH will  decrease. So the correct option will be A.

Acid is a chemical substance which can give H⁺ ions in water. Higher the hydrogen ion concentration higher will be the acidity.

Acidity is usually measured using pH scale. 7 in the pH scale is neutral. Lower than 7 it is acidic and higher than 7 is basic. Equation for the pH is as follows;

pH = -log[H⁺]

That means higher the concentration of hydrogen ions, lower will be the pH.

The half-life of uranium-235 (U-235) is 704 million years. Therefore, after three half-lives, the amount of U-235 remaining will be 15.624g.

(1/2)^3 = 1/8
So, only 1/8th of the initial amount of U-235 will remain. We can calculate the amount of U-235 remaining as:
125 g × (1/8) = 15.625 g
So, 15.625 g of U-235 will remain after 3 half-lives.
The time it takes for three half-lives to pass can be calculated as:
3 × 704 million years = 2.112 billion years
Therefore, 2.112 billion years will have passed after 3 half-lives.
Note that the calculation assumes that the decay of U-235 follows first-order kinetics and that the decay products do not interfere with the decay process. Additionally, the calculation neglects any effects due to the changing abundance of U-235 in natural uranium over time, as U-235 is a radioactive isotope that is continuously decaying in the Earth's crust.

Answer:

The rate law is the equation that describes how the reaction rate depends on the concentrations of the reactants. The rate law for a reaction cannot be determined based solely on the chemical formula of the reactant, as the reaction mechanism, conditions, and other factors can all affect the rate.

The overall balanced equation for the reaction is not provided, so it is not possible to write the rate law or determine the intermediates without additional information. To determine the rate law and intermediates, a detailed study of the reaction conditions, mechanism, and kinetics is necessary.

The postulates of the kinetic-molecular theory of gases are as follows: There are very minute particles in the gases.

Each of the gas laws that have been established through experiment may be explained by the kinetic molecular theory. A gas's pressure is created by collisions between its particles and the container's walls. A force is applied to the wall each time a gas particle strikes it.

The kinetic-molecular theory of gases makes the following assumptions about ideal gas molecules: (1) constant motion; (2) negligible volume; (3) negligible intermolecular forces; (4) perfectly elastic collisions; and (5) average kinetic energy proportional to the absolute temperature of the ideal gas.

A limiting reactant problem is a type of stoichiometry problem that involves determining which reactant in a chemical reaction will be completely consumed, and therefore limit the amount of product that can be formed.

The key clue that a problem is a limiting reactant problem is the presence of information about the amounts or masses of two or more reactants that are involved in a chemical reaction. In a limiting reactant problem, you are typically given the amounts of two or more reactants, and asked to determine the amount of product that can be formed.

To solve a limiting reactant problem, you must first determine the balanced chemical equation for the reaction, and then use stoichiometry to calculate the theoretical amount of product that can be formed from each reactant. The reactant that produces the smallest amount of product is the limiting reactant, because it will be completely consumed in the reaction, while the other reactant(s) will be left over.

The calculation of the limiting reactant and the amount of product produced from it is what sets a limiting reactant problem apart from other stoichiometry problems.

Answer:

15.0 liters of HN3 are needed to react completely with 30.0 liters of NO.

Explanation:

The amount of HN3 required to react completely with a given volume of NO can be determined by using the balanced chemical equation for the reaction. The reaction between HN3 and NO is given by:

4 HN3 + 5 NO → 4 HNO3 + N2

From the equation, we can see that for every 4 moles of HN3 that react, 5 moles of NO are consumed. To determine the amount of HN3 needed to react with a given volume of NO, we can convert the volume of NO to moles and then use the stoichiometry of the reaction to find the number of moles of HN3 required.

For example, if we have 30.0 liters of NO, we can convert it to moles using the ideal gas law:

30.0 L NO * (1 mole NO / 22.4 L) = 1.34 moles NO

Next, we can use the stoichiometry of the reaction to find the number of moles of HN3 required:

1.34 moles NO / (5 moles NO / 4 moles HN3) = 0.67 moles HN3

Finally, we can convert the number of moles of HN3 to liters:

0.67 moles HN3 * (22.4 L HN3 / 1 mole HN3) = 15.0 L HN3

Therefore, 15.0 liters of HN3 are needed to react completely with 30.0 liters of NO.

it would take approximately 28.1 seconds for 65% of the initial quantity of reactant to be consumed in this first-order reaction.

The time required for 65% of the initial quantity of reactant to be consumed in a first-order reaction can be determined using the equation:
t = (ln (N₀/N)) / k
Where:
t = time
N₀ = initial quantity of reactant
N = final quantity of reactant (0.35 times N₀, since 65% is consumed)
k = rate constant
Plugging in the given values, we get:
t = (ln (N₀/N)) / k
t = (ln (1/0.35)) / 0.0450 s⁻¹
t ≈ 28.1 seconds
The natural logarithm, ln, is used in this equation because the reaction is first-order. In general, for a reaction of order n, the equation would be: t = (1/(nk)) x [(N₀)ⁿ - (N)ⁿ].

The molecular formula of a substance can be determined from its elemental composition. In this case, we know that lysine contains two nitrogen atoms, 19.2% nitrogen, 9.64% hydrogen, 49.3% carbon, and 21.9% oxygen by mass.

For nitrogen, the atomic weight is 14.01 g/mol, so the number of nitrogen atoms in the molecule can be calculated as follows:

mass of nitrogen = 19.2 g N / 100 g lysine = 0.192 g N

number of nitrogen atoms = 0.192 g N / 14.01 g/mol = 0.0137 mol Nnumber of nitrogen atoms = 0.0137 mol N * Avogadro's number = 8 nitrogen atoms

mass of hydrogen = 9.64 g H / 100 g lysine = 0.0964 g H

number of hydrogen atoms = 0.0964 g H / 1.01 g/mol = 0.0953 mol H

number of hydrogen atoms = 0.0953 mol H * Avogadro's number = 17 hydrogen atoms

mass of carbon = 49.3 g C / 100 g lysine = 0.493 g Cnumber of carbon atoms = 0.493 g C / 12.01 g/mol = 0.0409 mol C

number of carbon atoms = 0.0409 mol C * Avogadro's number = 7 carbon atoms

mass of oxygen = 21.9 g O / 100 g lysine = 0.219 g O

number of oxygen atoms = 0.219 g O / 16.00 g/mol = 0.0137 mol O

number of oxygen atoms = 0.0137 mol O * Avogadro's number = 9 oxygen atoms

862.4 grams of carbon dioxide will be produced when 6.2 moles of propane, C₃H₈ is burned in oxygen

From the equation, we can see that 1 mole of propane takes 3 moles of Carbon dioxide in a ratio of 1:3

It's given that 6.2 moles of propane are burned, so using the ratio 1:3, we get 6.2 × 3 = 19.6 moles of Carbon dioxide

Now to get the mass of Carbon dioxide, we have to multiply 19.6 moles of carbon dioxide by its molar mass

the molality of a solution containing 125 grams of iodine (i2) and 750 grams of ccl4 is 0.657m

Molality is defined as the number of moles of solute per kilogram of solvent. To find the molality of the solution, we need to first calculate the number of moles of iodine and the mass of the solvent, which is carbon tetrachloride.

The molar mass of iodine is 126.9 g/mol, so 125 grams of iodine is equal to 0.985 moles (125 g / 126.9 g/mol).
The mass of the solvent, carbon tetrachloride (CCl4), is 750 grams.

Next, we need to convert the mass of the solvent to kilograms, which is 0.750 kg.
Using the formula for molality, we can calculate the molality of the solution:
molality = moles of solute / mass of solvent in kg
= 0.985 moles / 0.750 kg
= 1.313 m

Therefore, the molality of the solution is 0.657 m.
