<span>sulfurs electronic configuration is
1s2 2s2 2p6 3s2 3p4
so for the 3p sublevel
principal quantum no - 3
angulum quantum no - 1
magnetic quantum no - (-1) or 0 or (-1)
spin quantum no - (+1/2) or (-1/2)
so the quantum numbers will be
[ 3 , 1, -1 , +1/2 ] or [ 3 , 1, -1 , -1/2 ]
[ 3 , 1, 0 , +1/2 ] or [ 3 , 1, 0 , -1/2 ]
[ 3 , 1, 1 , +1/2 ] or [ 3 , 1, 1 , -1/2 ]

Answer:
in the presence of water H2O
Na2CO3 (S) --> 2Na+ (aq)+ (CO3)2-(aq)
One mole of sodium carbonate produces two moles of Na+ ions
Therefore 0.207 moles produces 0.414 moles of Na+ ions
= 0.414 moles of Na+ ions
Explanation:
In water
Na2CO3 --> 2Na+ (aq)+ (CO3)2-(aq)
In a limited reaction, the carbonate ion reacts with the water molecules as follows
(CO3)2-(aq) + H2O←→HCO3-(aq) + OH-(aq)
sodium carbonate or soda ash dissolves in water to give 2 sodium cations and one carbonate anion
Answer:
0.056 M
Explanation:
To calculate the concentration of h we must use the following formula:
10^-pH
So lets plug in our pH:
10⁻¹.²⁵
When we plug this into our calculator our answer is
0.056 M
