Question

What’s the predicted product of Zn + H2SO4

Answer 1

Single replacement

Step-by-step explanation:

Starts with an element and compound, then switches and creates new element and

compound.

Cations will switch with cation, if single element is cation. Anion will switch with

anion if single element is anion.

• Break compound into respective élemonts/ions and their charges, and switch

elements/ions for product,

Examples

Reactants. Zn + H SO

Break into elements/ions:

(Zn ) + (H)(SO, )

Cations/anions switch! CrissCross for final compound. Don't forget

special 7 for single element!

• Products: H2+ ZNSO

Balance the equation.

Answer 2

ZnSO4 + H2

Step-by-step explanation:

Zn + H2SO4

ZnSO4 + H2 - since there is only one on the left side, H2 is left by itself.
