<h2>0.44 </h2>Explanation:
The pH of a solution can be found by using the formula
From the question we have
We have the final answer as
<h3>0.44</h3>Hope this helps you
Each carbon atom will react with 4 hydrogen atoms to form methane (
) Since there are 2 hydrogen atoms in a hydrogen molecule (
) then each carbon atom will react with 2 hydrogen molecules. Since there are 22 hydrogen molecules half as many methane molecules will be formed, so 11. Then we can subtract 11 from 34 to find the number of carbon atoms left over.
So in summary, 11 methane molecules will be formed and there will be 23 carbon atoms left over.
So in summary, 11 methane molecules will be formed and there will be 23 carbon atoms left over.
(a) 33.6 L of oxygen would be produced.
(b) 106 grams of would be needed
1 mole of gas = 22.4 L
(a) From the equation, 2 moles of produce 3 moles of
. 1 mole of
will, therefore, produce 1.5 moles of
.
1.5 moles of oxygen = 22.4 x 1.5 = 33.6 L
(b) 22.4 L of is produced at STP. This means that 1 mole of the gas is produced.
From the equation, 1 mole of requires 1 mole of
.
Molar mass of = (23x2)+ (12)+(16x3) = 106 g/mol
Mass of 1 mole = 1 x 106 = 106 grams
