a sample of hydrogen gas (h2) is mixed with water vapor (h2o (g)). the make sure has a total pressure of 811 torr, and the water
Alborosie

Answer:

n=0.430molH_2

Explanation:

Hello!

In this case, considering the partial Dalton's law of partial pressures, we can notice that the total pressure equals the pressure of steam and the pressure of hydrogen, which can be determined as shown below:

p_T=p_H+p_w\\\\p_H=811torr-12torr=799torr*\frac{1atm}{760torr}\\\\p_H=1.05atm

Thus, by using the ideal gas law, we can compute the moles of hydrogen as shown below:

PV=nRT\\\\n= \frac{PV}{RT}=\frac{1.05atm*10.0L}{0.082\frac{atm*L}{mol*K}*298K}\\\\n=0.430molH_2

Best regards!

Consider the balanced equation below.
Karo-lina-s [1.5K]

The correct option is (a) H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2

<h3>What is molar Ratio ?</h3>

Molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation

the balanced equation is as follows ;

2H₂S + 3O₂ --> 2SO₂ + 2H₂O

molar ratio can be determined by the coefficients of the compounds in the balanced reaction.

coefficient is the number in front of the chemical compound

coefficients for the compounds in this reaction are as follows ;

  • H₂S - 2
  • O₂ - 3
  • SO₂ - 2
  • H₂O - 2

therefore, correct option is (a) H₂S:SO₂ = 2:2 and O₂:H₂O = 3:2

One liter of air contains about 0.21 L of oxygen. When filled, the human lungs hold about 6.0 L of air. How much oxygen is in th
masya89 [10]
Since we are told that 1L of air contains 0.21L of oxygen, you can use the conversion (0.21L O₂)/(1L air).  That means that you can just multiply 6.0L by 0.21L to get 1.26L of O₂.
that means that the lungs can hold about 1.26L of oxygen.
I hope this helps.  Let me know if anything is unclear.
