I'm not so sure but I would say it could be an iconic bond!
I think the answer is C but I also feel it should be A...... but I think its C
The layer that we live in is the Troposphere.
Hope this answer is correct.
H2O, also known as water, stands for two hydrogen atoms and one oxygen atom. Hope this helps! ^^
Balanced chemical equation:
2 H2 + 1 O2 = 2 H2O
4 g H2 -------> 32 g O2 -----------> 36 g H2O
↓ ↓ ↓
14.0 g ---------> 2.0 g O2 ----------> mass H2O ?
32 * mass H2O = 2.0 * 36
32 * mass H2O = 72
mass of H2O = 72 / 32
mass of H2O = 2.25 g
hope this helps!.
