Do this make sense? I'm a chmistry newbie so I'm not sure?
a) NaBr → Na + Br2
b) Ca + AlF3 → Al + CaF2
c) Ba + O2 → BaO
d) MgS + HI → H2Mg + SI2
e) Mg(OH)2 + HF → H2Mg + (OH)F
Answer:
yeah u dont need to balance the equation! all u need is to say which one is the reactant and which are the products!
eg: NaBr decomposes to make Na+Br2 so NaBr is the reactant and Na+Br2 are the products
a, b, c are OK
d should be MgS + HI yielding MgI2 + H2S
e should be the same as d
Mg(OH)2 + HF yielding MgF2 + H20
without balancing
The Mg and H are positive and will not combine.
a) 2NaBr >> 2Na + Br2
b) 3Ca + 2AlF3 >> 2Al + 3CaF2
c)2 Ba + O2 >> 2BaO
d) MgS + 2HI >> H2S + MgI2
e) Mg(OH)2 + 2HF >> MgF2 + 2H2O
2NaBr >> 2Na + Br2
3Ca + 2AlF3 >> 2Al + 3CaF2
2 Ba + O2 >> 2BaO
MgS + 2HI >> H2S + MgI2
Mg(OH)2 + 2HF >> MgF2 + 2H2O
