Answer:
Since the repulsions on the bond pairs in H2O molecule are greater than that in NH3, the bond angle in water is less than that of ammonia...
Answer:
0.5 M
Explanation:
First we have to start with the <u>molarity equation</u>:
We need to know the<u> amount of moles and the litters</u>.
If we have 100 mL we can convert this value to “L”, so:
Now we can continue with the moles, for this we have to know the <u>formula of sodium sulfate</u>
, with this formula we can <u>calculate the molar mass</u> if we know the atomic mass of each atom on the formula (Na: 23 g/mol, S: 32 g/mol, O: 16 g/mol). We have to multiply each atomic mass by the amount of atoms in the formula, so:
In other words:
Now we can <u>calculate the moles</u>:
Finally, we can <u>calculate the molarity:</u>
I hope it helps!
North magnets attract the opposite side in this case south would attract to north and vise versa if it was negative it would attract to positive and vise versa
