Practice: Determine the products, balance the equation, and identify as organic or inorganic combustion reaction (circle).
1)
Ca + O2
Inorganic or Organic combustion?
2)
C3H2O +
02
Inorganic or Organic combustion?

1. Inorganic combustion

2. Organic combustion

Given

The chemical equations

Required

Balanced equation

Solution

Organic compounds have the characteristic that there is a chain of carbon atoms, while inorganic does not have a chain of carbon atoms

The reaction of a substance with oxygen is called a combustion reaction

Complete combustion of carbon compounds will get CO₂ gas, whereas if it is not complete it will produce CO gas

So Organic : contain a carbon atom (and often a hydrogen atom)

1. Ca + O₂ ⇒ CaO₂

Inorganic combustion⇒does not contain carbon

2. C₃H₂O + 3O₂ → 3CO₂ + H₂O

Organic combustion

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
