A 20 ml mixture of C4H4 and C2H2 undergoes sparking in gas eudiometer  with just sufficient amount of O2 and shows contraction of 37.5ml . What is the volume (in ml) of C2H2 in mixture?Solution

Acetylene (C2H2) burns in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). 8.64 L of gaseous acetylene (C2H2) is burned at STP according to the equation:                            2C2H2 (g) + 5O2 (g) ⟶ 4CO2 (g) + 2H2O (l)a. What is the volume of O2 required for complete combustion?b. What is the volume of CO2 produced upon complete combustion?c. How many moles of CO2 are produced upon complete combustion?

If 484 L of a gas is collected over water at 24.1°C at an atmospheric pressure of 103.2 kPa, what is the volume of the dried gas at 24.5 °C and 99.9 kPa? (The vapour pressure of water is 2 kPa.)

A gas at a volume of 4 liters is at a pressure of 2 atm. The volume is changed to 16 Liters, what must the new pressure be?

According to this balanced chemical equation, what volume of C2H2 is required to form 40.0 L of CO2 ?                  2 C2H2 (g) + 5 O2 (g) → 2 H2O (g) + 4 CO2 (g)Group of answer choices44.880.0 L100 L20.0 L

A sample of oxygen gas occupies a volume of 400 mL at 50oC and 250 mmHg of pressure. What will its volume be at STP?
