Propane can be turned into hydrogen by the two-step reforming process. In the first step, propane and water react to form carbon
Liono4ka [1.6K]

Answer: The net chemical reaction:

C_3H_8(g)+6H2_O(g)\rightarrow 10H_2(g)+3CO_2(g)

Explanation:

Step  1 : Propane reacts with water to form carbon monoxide and hydrogen gas

C_3H_8(g)+3 H_2O(g)\rightarrow 3 CO(g)+7 H_2(g)...[1]

Step 2 : carbon monoxide formed in above step reacts with water tio form hydrogen gas and carbon dioxide.

CO(g)+H_2O(g)\rightarrow H_2(g)+CO_2(g)...[2]

On Adding [1] and 3 × [2] we get overall balanced chemical reaction for the production of hydrogen from propane and water:

C_3H_8(g)+6H_2O(g)\rightarrow 10H_2(g)+3CO_2(g)

1 mole of propane reacts with 6 moles of water vapor to gve 10 moles of hydrogen gas and 3 moles of carbon dioxide.

A 1.0-l buffer solution initially contains 0.30 mol of nh3 and 0.30 mol of nh4cl what mass of the correct reagent should you add
WARRIOR [948]
To find the mass of reagent to be added in the reaction, we need to determine the pH of the buffer. Using the following equation

pH= pKa + log ([NH3] / [NH4+])
     = 9.26 + LOG ( 0.3 / 0.3)
     = 9.26

[h+]= 5.5x10^-10 M, you need to increase that concentration for a ph of 8.6, [H+] needs to be 2.51x10^-9M

2.51x10^-9 moles - 5.5x10^10 moles = 1.96x10^-9 moles 

1.96x10^-9 x 36.45g/mole = 7.14x10^-8 g

So the mass of HCI that you should add to the reaction is 7.14x10^-8 g

The partial pressure of N2 in a mixture of gases, where the total pressure is 1.50 atm, is 300. torr. What is the mole fraction
makvit [3.9K]

Answer:

The mole fraction of N₂ is 0.26.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

PT = PA + PB

This relationship is due to the assumption that there are no attractive forces between the gases.

Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture. The mole fraction is a dimensionless quantity that expresses the ratio of the number of moles of a component to the number of moles of all the components present.

So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:

PA = XA * PT

In this case:

  • PA= PN₂= 300 torr
  • XA=XN₂= ?
  • PT= 1.50 atm= 1140 torr (being 1 atm= 760 torr)

Replacing:

300 torr= XN₂*1140 torr

Solving:

X_{N_{2} } =\frac{300 torr}{1140 torr}

XN₂= 0.26

<u><em>The mole fraction of N₂ is 0.26.</em></u>
