How do substances change into different substances during chemical reactions

icang [17]

Answer:

Chemical reaction are irreversible. Some of the example of chemical reaction are cooking, rusting, and burning. During a chemical reaction, the composition of substances changes and the particles rearrange to form a new substance. The new substance formed after chemical reaction of substance has different physical and chemical properties.

When a chemical reaction occur, the atoms or molecules of the substances change its physical and chemical properties such as while cooking of vegetable, the molecules of vegetable undergo changes in their properties and form a new substance which is different from the earlier.

5.911 grams of manganese dioxide and 1.224 gram of water are consumed.

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

The given reaction balanced equation is:

Zn(s) + MnO₂(s) + H₂O(l) → ZnO(s) + Mn(OH)₂(s)

<h3>How to find the number of moles ?</h3>

To find the number of moles use the expression:

Number of moles = $\frac{\text{Given mass}}{\text{Molar mass}}$

Here,

Mass of Zn = 4.50 g

Molar mass of Zn = 65.4 g/mol

Now put the value in above expression

Number of moles of Zn = $\frac{\text{Given mass}}{\text{Molar mass}}$

= $\frac{4.5\ g}{65.4\ \text{g/mol}}$

= 0.068 mol

Mass of MnO₂ = Moles of MnO₂ × Molar mass of MnO₂

= 0.068 mol × 86.9368 g/mol

= 5.911 g

Mass of H₂O = Moles of H₂O × Molar mass of H₂O

= 0.068 mol × 18.0 g/mol

= 1.224 g

Thus from the above conclusion we can say that 5.911 grams of manganese dioxide and 1.224 gram of water are consumed.
