Answer

P4O10 + 6 H2O -> 4 H3PO4 Al2S3 + 6H2O -> 2Al(OH)3 + 3 H2S

Work Step by Step

Write the unbalanced chemical equation with the correct chemical formulas and states. First balance phosphorus with a coefficient of 4 on the right side, then balance hydrogen with a coefficient of 6 on the left side. All atoms are now balanced. Write the unbalanced chemical equation with the correct chemical formulas. First balance aluminum with a coefficient of 2 on the right side. Then balance sulfur with a coefficient of 3 on the right side. Finally balance hydrogen and oxygen simultaneously with a coefficient of 6 on the left side. All atoms are now balanced.
