Answer:

(a) When aqueous solution of hydrochloric and ammonia chemically react together then it results in the formation of ammonium chloride.

The reaction equation for this reaction is as follows.

Now, ioni equation for this reaction is as follows.

Cancelling the spectator ions, the net ionic reaction equation is as follows.

(b) When sodium hydroxide chemically reacts with ammonium chloride then it forms ammonia, water and sodium chloride as follows.

Now, the total ionic equation will be as follows.

Cancelling the spectator ions from the above equation. Then the net ionic equation will be as follows.

Answer:

Fe₂O₃ and C are reactants

Fe and CO₂ are products

Explanation:

Reactants:

Chemical species that are present on left side of chemical reaction equation are called reactants.

Product:

Chemical species that are present on right side of chemical reaction equation are called product.

Chemical equation:

2Fe₂O₃ + 3C → 4Fe + 3CO₂

In this reaction 2 mole of iron oxide is react with three moles of carbon and produced four moles of iron and three moles of carbon dioxide. There are equal numbers of atoms of all elements present on both side of chemical reaction so this reaction follow the law of conservation of mass.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

A solution is prepared by mixing 93.0 mL of 5.00 M HCl and 37.0 mL of 8.00 M HNO3. Water is then added until the final volume is

Charra [1.4K]

Answer:

$[H^{+}] = 0.761 \frac{mol}{L}$

$[OH^{-}]=1.33X10^{-14}\frac{mol}{L}$

$pH = 0.119$

Explanation:

HCl and HNO₃ both dissociate completely in water. A simple method is to determine the number of moles of proton from both these acids and dividing it by the total volume of solution.

$n_{H^{+} } from HCl = [HCl](\frac{mol}{L}). V_{HCl}(L) \\ n_{H^{+} } from HNO_{3} = [HNO_{3}](\frac{mol}{L}). V_{HNO_{3}}(L)$
