The law of conservation of matter tells us that the total number of atoms does not change in a chemical reaction and thus mass is conserved. Select ALL of the reactions that obey the law of conservation of matter.
A) 4 NH3 + 5 02- 4 NO + 6 H20
B) 8 H25 + 8 C12 - Sg + 16 HCL
C) CH4 + 2 02 - CO 2 + H20
D) HCL + K2CO3 -- KCl + H2O + CO2
E) 2 Al(OH)3 + 3 H2S04 - AL2(SO4)3 + 6H20
