When a compound containing C, H and O is completely combusted in air what reactant besides the hydrocarbon is involved in the reaction is Oxygen.
<h3>What is hydrocarbon?</h3>
A hydrocarbon is an organic molecule composed completely of hydrogen and carbon in organic chemistry. Group 14 hydrides include hydrocarbons. Hydrocarbons are often colourless and hydrophobic, with scents that are weak or exemplified by gasoline and lighter fluid. They exist in a wide range of molecular forms and phases, including gases (like methane and propane), liquids (like hexane and benzene), low melting solids (like paraffin wax and naphthalene), and polymers (such as polyethylene and polystyrene). Hydrocarbon refers to naturally occurring petroleum, natural gas, and coal, as well as their hydrocarbon derivatives and refined forms, in the fossil fuel industry. The primary source of energy on the planet is the combustion of hydrocarbons.

Answer:

Explanation:
Hello!
In this case, since the by-mass percent of a solution is a measure of the mass of the solute over the mass of the solution:

As we know the mass of the solution and the by-mass percent, we can compute the mass of glucose in the 480 g of solution:

Thus, by plugging in the data, we obtain:

Finally, since the solution is made up of glucose and water, we compute the mass of water as follows:

Best regards!
Answer: m = 17.5 g Cl
Explanation: To find the mass of Cl we will need to convert the moles of Cl to mass using the relationship of 1 mole = molar mass of Cl.
0.500 mole Cl x 35 g Cl / 1 mole Cl
= 17. 5 g Cl
Answer: 224 grams
Explanation:
2H2 + O2 = 2H2O
This implies that 2 moles of oxygen is needed to react with one mole of oxygen to form 2 moles of water
It also implies that
2 moles of hydrogen requires 32 grams of oxygen
14 moles of hydrogen would require ? grams of oxygen
14/2 x 32 = 224 grams
