Question

1. Indicate whether the following chemical equations adhere to the Law of Conservation of Mass.
   (Answer “yes” or “no”) (1 point each)

1. 2H₂   +   O₂ ----> 2H₂O   

2. 2N₂ +   3H₂ ----> 2NH₃

3. C₃H₈ +   3O₂ ----> 3CO₂   +   4H₂O

d.   2Na₃PO₄ + 3MgCl₂ ----> 6NaCl + Mg₃(PO₄)₂

Answer 1

Anower Balaneing each atom in reaution it every cetom is balanced meare equation as adhere to law of Conservation @ 2H₂ + O 2H20 [yes] every atom is balanced 6 2N2 + 3H₂ 2NH3 [no ] Natom a not balanced - € G Hg+ 3% - 3602 + 4H2O Thol ino o n o atom to not balanced a zna Poy & angel - Gwall + Mg (Poy), Tyes) every atom is balanced,
