If every oxygen ion (combined with an aluminum ion) has a charge of –2, what must the charge of each aluminum ion be? How can yo

u tell this? Also, what has to happen to an uncharged aluminum atom so that it will bond with oxygen?

Each aluminium ion should have a charge of +2, because the sum of oxidation numbers must be zero.

The uncharged aluminium atom must lose two electrons to become an ion with +2 charge.

If a 2.50 liter container is filled with Ne gas at a pressure of 650 mm Hg and at 25°C, what mass of Ne is in the container?
seraphim [82]

Answer:

1.76 g is the mass of Ne is in the container.

Explanation:

We use the equation given by ideal gas which follows:

PV=nRT

where,

P = pressure of the gas = 650 mm Hg

V = Volume of the gas = 2.50 L

T = Temperature of the gas = 25^oC=[25+273]K=298K

R = Gas constant = 62.3637\text{ L.mmHg }mol^{-1}K^{-1}

n = number of moles of Ne gas = ?

Putting values in above equation, we get:

650mmHg\times 2.50L=n\times 62.3637\text{ L.mmHg }mol^{-1}K^{-1}\times 298K\\\\n=\frac{650\times 2.50}{62.3637\times 298}=0.0874mol

Also, molar mass of Ne = 20.1797 g/mol

So, Mass = Moles\times Molar\ mass = 0.0874\times 20.1797 g = 1.76\ g

<u>1.76 g is the mass of Ne is in the container.</u>
