If a car produces 62g of co2, how many grams of o2 are used up in the reaction?

Given:

Amount of CO2 produced = 62 g

To determine:

Amount of O2 consumed

Explanation:

If ethanol (C2H5OH) is the fuel used during combustion then the reaction is:

C2H5OH + 3O2 → 2CO2 + 3H2O

Based on the reaction stoichiometry:

3 moles of O2 will produce 2 moles of CO2

# moles of CO2 produced = 62 g/ 44 g.mol-1 = 1.4091 moles

Therefore,

# moles of O2 consumed = 1.4091 *3/2 = 2.1137 moles

Mass of O2 used up = 2.1137 moles * 32 g/mole = 67.64 g

Ans: The mass of O2 used up during combustion of ethanol would be around 68 g

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
