25) 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 0 -- 4 NO.6H,0
B) 8 H25+ 8 Cl2 - 5; 16 HCI
CH, 20, - CO + H2O
D) HCI + K2CO3 - KCI + H2O + CO2
E) 2 Al(OH)3 + 3 H250- Al2(50)3 + 6H20
