Question

All of the following are balanced equations. State the

number of atoms of each element in the reactants and in
the products.
a. 2Na(s) + Cl2(8) =2NaCl(s)
b. PC13(1) + 3H2(8) =PH3(8) + 3HC1()
c. P4010(s) + 6H2O(l) =4H3PO4(aq)

Answer 1

Answer: a: reactants Na-2 Cl-2

Products: Na-2 Cl-2;

b: reactants P-1 Cl-13 H-6 Products P-1 H-6 Cl-13

c: reactants P-4 H-12 O-16

Products H-12 P-4 O-16

Explanation: since these equations are balanced the atoms on of element on the reactants side will be same as the atoms of the same element of the product side
