Answer 1

14) Reactant

15) 1 .Precipitation reaction equation

16) The coefficient

17) 6.6242 × 10²⁴ atoms of oxygen

18) The product

20) The four states of matter are;

a) Solids

b) Liquids

3) Gas

4) Plasma

21) The total number of atoms in the product is 2.7099 × 10²⁵ atoms.

Step-by-step explanation:

14) The left side of the chemical equation is the reactant

15) The coefficient is the number in font of the formula, here, the coefficient of the reactant C₁₂H₂₂O₁₁ is 1 .This is a precipitation reaction equation

16) The number 11 in front of the formula, H₂O, is called a coefficient

17) On mole of a substance is defined as containing one Avogadro's number,
`N_A` of molecules

`N_A` ≈ 6.022 × 10²³ mol⁻¹

In the reactant, C₁₂H₂₂O₁₁, there are 11 elements of oxygen in one mole of the reactants, which gives 11 × 6.022 × 10²³ = 6.6242 × 10²⁴ atoms of oxygen in one mole of the reactants

18) The right side of the chemical equation is called the product

20) The four states of matter are;

a) Solids

b) Liquids

3) Gas

4) Plasma

21) The number of elements on the product side are;

12 Carbon + 22 Hydrogen + 11 Oxygen = 45 Elements total

However, given that there are 12 moles of carbon, we have;

12 × 6.02 × 10²³ = 7.2264 × 10²⁴ atoms of carbon

For hydrogen, we have;

22 × 6.02 × 10²³ = 1.32484 × 10²⁵ atoms of hydrogen

For oxygen, we have;

11 × 6.02 × 10²³ = 6.6242 × 10²⁴ atoms of oxygen

The total number of atoms in the product is 7.2264 × 10²⁴ + 1.32484 × 10²⁵ + 6.6242 × 10²⁴ = 2.7099 × 10²⁵ atoms.
