Question 12 (1 point)
The following equations represent chemical reactions.
A. AI+6HCL--> 3H2+ALCL3
B. 3H2O2--> 3H2O+O2
C. 2MgF2+Li2CO3-->2MgCO3+LiF
D. P4+3O2--> 2P2O3
Which equation above shows that matter is conserved in a chemical reaction? (HINT: Matter is conserved when there are equal numbers of each type of atom on both sides of the equation. The equation is balanced.)
a
Reaction A
b
Reaction B
c
