Question

When balanced, which equations would have the coefficient 3 in front of the first set of atoms? Check all that apply. A. AgBr + GaPO4 → Ag3PO4 +GaBr3 B. H2SO4 + B(OH)3 → B2(SO4)3 + H2O C. Fe + AgNO3 → Fe(NO3)2 + Ag D. C2H4O2 +O2 → CO2 +H2O

Answer 1

Balancing the choices, we have as follows:

A. 3AgBr + GaPO4 → Ag3PO4 +GaBr3

B. 3H2SO4 + 2B(OH)3 → B2(SO4)3 + 6H2O

C. Fe + 2AgNO3 → Fe(NO3)2 + 2Ag

D. C2H4O2 +2O2 → 2CO2 + 2H2O

Therefore, the correct answers are option A and B. Hope this answers the question. Have a nice day.
