Answer:

Lithium nitrate and water are product of given reaction.

Explanation:

Word equation:

Nitric acid + lithium hydroxide → Lithium nitrate + water

Chemical equation:

HNO₃ + LiOH → LiNO₃ + H₂O

The given reaction is balanced. There are two hydrogen, four oxygen, one lithium and one nitrogen atoms are present on both side of equation.

This reaction completely 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.

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.

How many molecules of water are formed?

astraxan [27]

<u>Answer:</u> 3 moles of water are formed. The limiting reagent is Oxygen atom and the excess reagent is Hydrogen atom.

<u>Explanation:</u>

From the image provided, there are 8 moles of Hydrogen atom and 3 moles of Oxygen atom.

The equation for the formation of water is given by:

$2H+O\rightarrow H_2O$

By Stoichiometry,

1 mole of Oxygen atom reacts with 2 moles of Hydrogen atom.

So, 3 moles of Oxygen atom will react with = $\frac{2}{1}\times 3=6moles$ of Hydrogen atom.

The required amount of Hydrogen atom is less than the given amount of Hydrogen atom, hence, it is considered as an excess reagent.

Therefore, Oxygen atom is the limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

1 moles of oxygen atom produces 1 mole of water molecule.

So, 3 moles of oxygen atom will produce = $\frac{1}{1}\times 3=3moles$ of water molecule.

Thus, 3 moles of water are formed. The limiting reagent is Oxygen atom and the excess reagent is Hydrogen atom.
