Answer:

1) combustion

2) double replacement

3) combination

4) combustion

Explanation:

The combustion of a compound refers to the reaction of that compound with oxygen to produce heat and light. In reactions (1) and (4) above, ethanol and methane reacted with oxygen to yield carbon dioxde and water. This is a combustion reaction.

Reaction(2) is a double replacement reaction because the both cations exchange their anion partners in the product.

Reaction (3) is a combination reaction. It involves the joining of two elements to form a new compound.

Combustion analysis of toluene, a common organic solvent, gives 4.69 mg of co2 and 1.10 mg of h2o. if the compound contains only
BartSMP [9]
CₓHₐ + (x+a/4)O₂ = xCO₂ + a/2H₂O

n(CO₂)=4.69 mg/44.01 mg/mmol = 0.1066 mmol

n(H₂O)=1.10 mg/18.02 mg/mmol = 0.06104 mmol

C : H = 0.1066 : 0.06104*2 = 0.1066 : 0.12208 = 1 : 1.1453 = 7 : 8

C₇H₈ + 9O₂ = 7CO₂ + 4H₂O
