What's the charge on Ni in the compound NiCi3? *

ss7ja [257]

Answer:

Explanation:

Chlorine is anion with a -1 charge. But they are three chlorine atoms.

-1 * 3 = -3

So they have a -3 charge.

So to balance the compound, the nickel has to be a cation with a +3 charge.

-3 + 3 = 0

Furthermore, a chemical bond always has a 0 charge. Remember that.

Hope it helped! Rate my answer a 5 star if correct.

Answer:

$V=162L$

Explanation:

Hello,

In this case, we can compute the required volume by using the ideal gas equation as shown below:

$PV=nRT$

Thus, solving for the volume and considering absolute temperature (in Kelvins), we obtain:

$V=\frac{nRT}{P}= \frac{4.70mol*0.082\frac{atm*L}{mol*K}*(21+273)K}{0.700atm} \\\\V=162L$

Best regards.
