How to Balance:

Word equation: Sulfuric acid + Zinc → Zinc sulfate + Hydrogen gas

Type of Chemical Reaction: For this reaction we have a single displacement reaction.

Balancing Strategies: This is a double replacement reaction where does Zn up replaces the H in the sulfuric acid.

It's a straightforward reaction to balance just be sure to count of the atoms on each side of the equation carefully.

For a complete explanation, watch:

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).
Never change the subscripts (the small numbers after elements).
