Identify the reactant(s) in the chemical reaction, CO2 + H2O → H2CO3. a
CO2, H2O, and H2CO3
b
CO2 and H2O
c
CO2
d
H2CO3

b. CO2 and H2O

Explanation:

Reactants are substances that undergo change during a reaction. They are on the left side of the arrow and turn into products (aka the right side).

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
