Ronch [10]

Answer:

Answer

4.0/5

4

Explanation:

The balanced chemical equation will be;

H2SO4 + 2NaOH → Na2SO4 + 2H2O

The equation for the reaction is balanced by using coefficients; 1,2,1,2

According to the law of conservation of mass the mass of the reactants should be equal to the mass of the products.

For the law of conservation of mass to be obeyed, chemical equations must always be balanced.

Explain where plants get their matter from?

The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.
