Container A holds 717 mL of an ideal gas at 2.80 atm. Container B holds 174 mL of a different ideal gas at 4.30 atm. Container A
horsena [70]

Answer:

3.09 atm

Explanation:

Given that:

Volume of container A = 717 mL

Pressure of container A = 2.80 atm

Volume of container B = 174 mL

Pressure of container B = 4.30 atm

Now, if the valve are being removed and the gases are allowed to mix together; then

The total final pressure can be calculated by using the formula:

P_f = \dfrac{P_AVA+P_BV_B}{V_A+V_B}

P_f = \dfrac{2.80*717+4.30*174}{717+174}

P_f = \dfrac{2007.6+748.2}{891}

P_f = \dfrac{2755.8}{891}

\mathbf{P_f =3.09 \ atm}

Fe2O3 + H2 --> Fe + H2O
sveticcg [70]
A) 10.0g of Iron is \frac{10.0}{55.8}=179mmol of Iron.

One mole of dihydrogen is required to form one mole of iron, hence you'll need 0.179*1.00=0.179g of dihydrogen.

B) Likewise : 2.50g of Iron is \frac{2.50}{55.8}=44.8mmol of Iron, hence we'll need 44.8*(3*16+2*55.8)=7.15g of Fe2O3.
