Ch4, o2 > co2, h20 1. Does this chemical reaction follow the law of conservation of matter?

2. How many atoms of hydrogen do you have in the reactants? How many atoms of hydrogen to you have in the product?

3. Give 1 reason why this chemical reaction/equation follows OR does not follow the law of conservation of matter?

1. No, it doesn't.

2. 4 Hydrogen atoms are on the reactants side and 2 hydrogen atoms on products side.

3. Because the mass of reactants is not equal to the mass of the products thus it doesn't follow the law of conservation of matter.

But on balancing the eqn,

CH4 + 2O2 > CO2 + 2H2O

The above eqn will follow the law of conservation of matter because the mass of reactants is equal to the mass of products.

if you're asking what comes out, it's steam.
