HCl + NaHCO3 = NaCl + H2O + CO2
We have 0.033*0.2 = 0.0066 mol of Hcl
According to reaction we need the same amount of NaHCO3
M(NaHCO3) = 23+1+12+48=84g/mold
m = 0.0066mol * 84g/mol = 0.5544g
It states the fact, which we now know, that electrons are responsible for the chemical bonding. According to this theory, valency is the number of electrons present in the outermost energy shell of the atom. This energy shell is called valency shell.
Answer:
15 atoms
increases
Explanation:
10 hydrogen atoms + 5 oxygen atoms = 15 atoms
Convert each amount of grams into moles:
I: 23.24g x 1 mol / 126.90g = 0.1831 mol I
C: 2.198 x 1 mol / 12.01g = 0.1830 mol C
N: 2.562 x 1 mol / 14.01g = 0.1829 mol N
Each element has roughly the same amount of moles, which means the whole number ratio between the elements is 1:1:1
Therefore the empirical formula is ICN
The change is that the air goes up then forms clouds.
