Mg + HNO3 -> Mg(NO3)2 + H2
On reactants side:
Mg=1
H=1
N=1
O=3
On products side:
Mg=1
H=2
N=2
O=6 (3×2)
Therefore to balance the equation, we must add 2 to HNO3 on the reactants side...
Mg + 2HNO3 -> Mg(NO3)2 + H2
Reactants:
Mg=1
H=2
N=2
O=6
Therefore, it's balanced.
Answer:
im wondering how you 45 and in middle school
Explanation:
but im also trying to find out this answer sooo
Answer:
The equation can be written as :-
=》Cu + AgNO3 -> Ag + Cu(NO3)2
so, the term suitable for the blank is :-
" Cu (NO3) 2 "
( note the equation isn't balnced )
balanced one is :
Cu + 2 AgNO3 -> 2 Ag + Cu(NO3)2
Answer:
C
