Document Summary

Balancing chemical equations: balance atoms in compounds first before atoms in pure elements, balance the free elements at last is balanced, check to make equation in the each type of atom certain on both sides. Consider the unbalanced equation for the combustion of hexane: + h2o(g) moles of o2 are required to react completely with 7. 2 mol c6h14. Solution: 2c6h14(g) + 19o2(g) 12co2(g) + 14h2o(g, 7. 2 mol c6h14 x. Substance that dissolves in water form solutions that conduct electricity are called electrolytes.
