Question

When the following molecular equation is balanced using the smallest possible integer coefficients, the values of these coefficients are:

________hydrochloric acid (aq) + ___________oxygen (g) → _________water (l) + ________chlorine (g)

Answer 1

The coefficients are; 4, 0, 2, 2

Step-by-step explanation:

The equation is given as;

HCl + O2 --> H2O + Cl2

Upon balancing the equation, we have;

4HCl + O2 --> 2H2O + 2Cl2
