Identify the equation(s) that is/are not balanced.

Question

Part: 0 / 3

Part 1 of 3

Check all that apply.

2K(s) + 02(g) + K2O(s)
2HCl(aq) + Ni(s) -+ NiCl2(aq) + H2 (g)
TiCl4(1) + 2H2O(1) -+ TiO2(s) + HCI(aq)
None of the above

Change the coefficient(s) to correctly balance the unbalanced equation.

Answer 1

2K(s) + O2(g) -> 2K2O(s)
2HCl(aq) + Ni(s) -> NiCl2(aq) + H2(g)
TiCl4(l) + 2H2O(l) -> TiO2(s) + 4HCl(aq)
