Answer:
moles H = 2 x 0.0649=0.130
ions = 0.130 x 6.02 x 10^23=7.81 x 10^22
Explanation:
Answer:
Combustion of hydrocarbons
Explanation:
The skeleton equation for a combustion reaction is:
How to remember:
Combustion means burning. When you make a fire, you need oxygen to keep it going (oxygen in the reactants). The fire produces carbon dioxide, which is bad for the environment.
Answer:
Coefficient of is more than 4
Explanation:
Oxidation:
- Balance charge: ......(1)
Reduction:
- Balance Cr:
- Balance O and H in acidic medium:
- Balance charge: .......(2)
gives balanced equation:
So coefficient of is more than 4
Answer:
Explanation:
stoichiometry is used in cooking because it helps you determine the amount or proportion of compounds you will need in a chemical reaction. Stoichiometry is present in daily life, even in the cooking recipes we make at home. The reactions depend on the compounds involved and how much of each compound is needed to determine the product that will result.
