Question #239db

Answer 1

Calcium is oxidized....

Explanation:

....and hydrogen ion is reduced....

`Ca(s) +H_2SO_4(aq) rarr CaSO_4(s)darr + H_2(g)uarr`

Answer 2

`Ca(s) + H_2SO_4(aq) \rightarrow CaSO_4(aq) + H_2(g)`

Explanation:

Remember,

Metal + Acid `\rightarrow` Metal Salt + Hydrogen

Therefore the equation would be:

`Ca(s) + H_2SO_4(aq) \rightarrow CaSO_4(aq) + H_2(g)`

Since this equation is a;ready balanced, you don't need to do anything more.

Hope that makes sense!
