Answer:
3.79 moles
Explanation:
To convert moles to gams of a substance we need to find the molar mass of the substance. For Ca(OH)₂ th molar mass is:
1Ca = 40.08g/mol
2O = 2*16g/mol = 32g/mol
2H = 2*1.01g/mol = 2.02g/mol
The molar mass is:
40.08g/mol + 32g/mol + 2.02g/mol = <em>74.1g/mol</em>
<em />
And moles are:
281g * (1mol / 74.1g) =
<h3>3.79 moles</h3>
Answer: Pauli exclusion principle: only two electrons can occupy the same orbital and they must have opposite spin directions
Explanation:
KauCl4 :
K = + 1
au = + 7
Cl = - 2
hope this helps!
It is ionic bond because of Na valency and it is alkali metal and cl is non metal and it’s valency , they both share electron and make ionic bonding .
