Acetylene reacts with oxygen to form carbon dioxide and water according to the following unbalanced reaction:

c2h2 (g) + o2 (g) → co2 (g) + h2o (g)

if we start with 38.7 g of acetylene and 13.7 g of oxygen, how many grams of the excess reactant are leftover after the reaction is complete?

report your answer to three significant figures.

Mass of excess reactant leftover after reaction is complete = 34.2 g .

Explanation:

Acetylene reacts with oxygen to form carbon dioxide and water, equation given is unbalanced

Firstly equation is balanced:

:

Here we come to know O2 is limiting reactant as it gives smaller amount of So is excess reactant.

Mass of excess reactant utilized:

Mass of excess reactant leftover after reaction is complete:

.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
