Question

Balance the following reaction:

Co(s) + H2SO4(aq) --> Co(SO4)2(aq) + H2(g)
What is the coefficient in front of H2SO4?

Answer 1

Answer: The coefficient is 1.

Step-by-step explanation:

In order to balance the chemical equation Co(s) + H2SO4(aq) --> Co(SO4)2(aq) + H2(g), it is necessary to add a coefficient of 1 in front of H2SO4. Hence, the coefficient for H2SO4 is 1.
