SO2+O2 SO3 how many moles of O2 needed to combust 100.0g of sulfur dioxide

Chemistry
1 answer:
Oksanka [162]3 years ago
6 0

2SO2 + O2 ------> 2SO3


1) M(SO2)= 32.0 + 2*16.0 = 64 g/mol


2) 100.0 g SO2 * 1 mol SO2/64 g SO2 = 1.5625 mol SO2


3) 2SO2 + O2 ------> 2SO3

2 mol 1 mol

1.5625 mol x mol


x= 1.5625/2=0.78125 ≈ 0.7813 mol O2


Answer: 0.7813 mol O2.

What volume of carbon dioxide gas can be collected from
alisha [4.7K]

Answer:

1.22 L of carbon dioxide gas

Explanation:

The reaction that takes place is:

  • CaCO₃ + HCl → CaCl₂ + CO₂ + H₂O

First we <u>determine which reactant is limiting</u>:

  • Calcium carbonate ⇒ 10.0 g CaCO₃ ÷ 100 g/mol = 0.10 mol CaCO₃
  • Hydrochloric acid ⇒ 0.100 L * 0.50 M = 0.05 mol HCl

So HCl is the limiting reactant.

Now we calculate the moles of CO₂ produced:

  • 0.05 mol HCl * \frac{1molCO_{2}}{1molHCl} = 0.05 mol CO₂

Finally we use PV=nRT to <u>calculate the volume</u>:

  • P = 1 atm
  • n = 0.05 mol
  • T = 25 °C ⇒ 25 + 273.16 = 298.16 K

1 atm * V = 0.05 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 298.16 K

  • V = 1.22 L

Find the volume of 56.0 grams of O2
N76 [4]

Answer:

39.2 L at STP

Explanation:

Convert the grams to moles first by dividing 56.0 by the molar mass of O2 (32.0) then convert to volume by multiplying by 22.4.

= 39.2 L
