5. In an oxyacetylene welding torch, acetylene (C2H2) burns in pure oxygen with a very hot flame. The reaction is: 2 C2H2 + 5 O2

gulaghasi [49]

11.375 g ethylene is consumed if 35.0 grams of oxygen is allowed to react and 7.875 ml of water will be produced when the 35.0 grams of oxygen is allowed to react.

<h3>What are moles?</h3>

A mole is defined as 6.02214076 × $10^{23}$ of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

According to the chemical equation for the combustion of ethylene, 5

moles of oxygen are required to react with 2 moles of ethylene, hence

$m_{_C_2_H_2}$ $= 35gX \frac{1 mol}{(2 \;X\; 16)g } X \frac{2 mol}{(5\;mol )} X \frac{26g}{1 mol }$

$m_{_C_2_H_2} = 11.375 g$

Similarly, 5 moles of oxygen are required as a reactant to produce 2 moles of water, thus

$m_{_H_2_O} = 35gX \frac{1 mol}{(2 \;X\; 16)g } X \frac{2 mol}{(5\;mol )} X \frac{18g}{1 mol }$

$m_{_H_2_O} = 7.875 g$

Given that the density of water is $1.0g ml^{-1}$ , therefore

$Density = \frac{Mass \;of \;water}{Volume \;of \;water}$

$Volume \;of \;water = \frac{7.875}{1.0 g ml^{-1}}$

The volume of water = 7.875 ml

What happens when two or more atoms react?

lisabon 2012 [21]

Atoms bond to form molecules: Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed.
