Answer: C_2H_2

Explanation:

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms. The general formula for these hydrocarbons is C_nH_{2n+2} and are called as alkanes.

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is C_nH_{2n} and C_nH_{2n-2} respectively.

C_4H_8 and C_2H_4 are alkenes.

C_4H_{10} is an alkane.

Thus C_2H_2 with general formula C_nH_{2n-2} is an alkyne.

How many kilojoules of heat are released when 0.72 mole of oxygen gas are used to combust methane?
KonstantinChe [14]

0.72 mole of oxygen would produce 320.4 kJ of heat.

<u>Explanation:</u>

CH₄ (g) + 2O₂ (g) → CO₂ (g) + 2H₂O (ℓ) + 890kJ

According to the equation,

2 moles of O₂ produces 890 kJ of heat

So, 0.72 moles of O₂ will produce:

= \frac{890}{2} X 0.72\\\\= 445 X 0.72\\\\= 320.4 kJ

Therefore, 0.72 mole of oxygen would produce 320.4 kJ of heat.
