Answer:
1. Yes, Chemical reaction follow the law of conservation of matter.
2. the same atom of hydrogen is in the reactants and the products.
3. chemical reaction follows the law of conservation of matter
Step-by-step explanation:
1. as we all know the law of conservation of matter states that matter ca neither be created nor destroy but its can be changed. this is related to chemical reaction as well, as the mass of a reactants must be equal to the mass of the products, for the equation to be balance.
2. the same number of atoms hydrogen will be found in the reactant and products for the equation to be balance.
for example, to form water,
reactants = 2 atom of Hydrogen will react with one atom of oxygen =H₂+O
products= H₂O (which is also two atom of hydrogen)
3. chemical reaction follows the law of conservation of matter because
the law of conservation of matter/mass obeys for any chemical reaction, the mass of products equals the mass of reactants.
