Answer:
it is a chemical reaction in which one element replaces an/other element in a compound. It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.
Answer:
I am a grade six student but I am very interested in chemistry
Explanation:
I sorry but this is NOT chemistry
1 Hydrogen 1s1
2 Helium 1s2
3 Lithium 2s1
a)
A: Copper
B: CuO
C:
D: $\mathrm{CuCO_3}$
E: $\mathrm{CO_2}$
F: $\mathrm{Cu(NO_3)_2}$
b)
$\mathrm{CuO+ H_2SO_4}\rightarrow \mathrm{CuSO_4 + H_2O}$
c)
$\mathrm{CuCO_3+ 2HNO_3}\rightarrow \mathrm{Cu(NO_3)_2+ CO_2+ H_2O}$
