As a liquid cools, what happens to the evaporation rate?

1 answer:

3 0

Evaporation is the rate at which liquid changes into gas. The higher the temperature the higher the increased rate of evaporation.

So if the liquid cools which means the temperature reduces, the rate of evaporation would decrease.

So evaporation rate decreases. B.

Gasoline is a mixture of compounds. A gasoline sample was found to be 2.851% (by mass) octane (C₈H₁₈). 482.6 g of gasoline is co

Pani-rosa [81]

Answer:

See below.

Explanation:

The mass of octane in the sample of gasoline is 0.02851 * 482.6 = 13.759 g of octane.

The balanced equation is:

2C8H18(l) + 25O2(g) ----> 16CO2(g) + 18H2O(g)

From the equation, using atomic masses:

228.29 g of octane forms 704 g of CO2 and 324.3 g of H2O

So the mass of CO2 formed from the combustion of 13.759 g of octane = (704 * 13.759) / 228.29

= 42.43 g of CO2.

Amount of water = 324.3 * 13.759) / 228.29

= 19.55 g of H2O.
