Writing Chemical Equations Write and balance the equation showing the reaction between zinc metal and aqueous sulfuric acid to form aqueous zinc sulfate, sulfur dioxide gas, and water.

1) 1 N2 + 3 H2  2 NH3

2) 2 KClO3  2 KCl + 3 O2

Explanation:

That would help!! Stay safe

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

i think   the answer is c hope i'm right
