Explanation:
Answer:
Explanation:
1) NaCl → Na + Cl₂
2) Na + HCl → NaCl + H₂
Chemical equation:
NaCl → Na + Cl₂
Balanced chemical equation:
2NaCl → 2Na + Cl₂
There are two moles of sodium and two mole of chlorine on both side of equation so given chemical equation is correctly balanced and follow the law of conservation of mass.
2)
Chemical equation:
Na + HCl → NaCl + H₂
Balanced chemical equation:
2Na + 2HCl → 2NaCl + H₂
There are two moles of sodium and two mole of chlorine and hydrogen on both side of equation so given chemical equation is correctly balanced and follow the law of conservation of mass.
Law of conservation mass
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
