The combustion of ethane ( C 2 H 6 ) produces carbon dioxide and steam. 2 C 2 H 6 ( g ) + 7 O 2 ( g ) ⟶ 4 CO 2 ( g ) + 6 H 2 O ( g ) How many moles of CO 2 are produced when 5.85 mol of ethane is burned in an excess of oxygen?

Twice as much... => 11.9 mole CO₂

Explanation:

From balanced equation ...

2 moles C₂H₆ => 4 moles CO₂ then

5.95 moles C₂H₆ => 2(5.95) moles CO₂ = 11.9 mole CO₂

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
