How many moles of ethane (C2H6) would be needed to react with 62.3 grams of oxygen gas?
Black_prince [1.1K]
The combustion of ethane is expressed in the balanced reaction C2H6 + 3.5O2= 2CO2 + 3 H2O. Given the mass of oxygen gas, we get the moles of ethane needed by converting this mass to mole (dividing my 32 g/mol), then multiply by 1/3.5 (stioch ratio) and the molar mass of ethane (30 g/mol). The answer is 16.69 grams ethane.

How does heat flow? Use the following keywords: heat, thermal energy, transfer, same, hot to cold, kinetic energy
Nitella [24]

Explanation:

is the movement of heat. ... Heat flows in solids by conduction, which occurs when two objects in contact with each other transfer heat between them. That happens because the molecules hit each other, and the faster moving molecules in the hot object spread that energy into the cooler object.
