A combustion reaction usually happens when a hydrocarbon is reacted with an oxygen molecule producing water and carbon dioxide. It is an exothermic reaction which means it releases heat as the process proceeds. It is a spontaneous process where it readily happens without any supply of energy. The total kinetic energy of the reactants is greater than the activation energy that is why heat is being released. Acetic acid is a carboxylic acid and is classified as a hydrocarbon so when reacted with oxygen, it would yield carbon dioxide and water. The balanced chemical reaction would be as follows
CH3COOH + 2 O2 = 2 CO2 +2 H2O
It’s a centrifuger there are many steps to this do I advise looking on the internet or i could explain if needed
Answer:
V₁ = 10 mL
Explanation:
Given data:
Initial volume of HCl = ?
Initial molarity = 3.0 M
Final molarity = 0.10 M
Final volume = 300.0 mL
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Initial molarity
V₁ = Initial volume of HCl
M₂ =Final molarity
V₂ = Final volume
Now we will put the values.
3.0 M ×V₁ = 0.10 M×300.0 mL
3.0 M ×V₁ = 30 M.mL
V₁ = 30 M.mL /3.0 M
V₁ = 10 mL
