Answer : The balanced equation for the complete combustion of cyclopentane will be :
Explanation :
As we know that the hydrocarbons can undergo complete or incomplete combustion that depends on the amount of oxygen available.
Complete combustion : It takes place when there is a good supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon dioxide and water as a product.
The general reaction will be :
Incomplete combustion : It takes place when there is a poor supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon monoxide, carbon dioxide and water as a product.
The general reaction will be :
As per question, the complete combustion of cyclopentane react with oxygen to gives carbon dioxide and water as a product.
Therefore, the balanced chemical reaction will be :
Answer:
0.0025g/cm³
Explanation:
Given parameters:
Mass of the brown sugar = 12.9g
dimension of the sugar = 8cm
unknown:
density of the sugar = ?
Solution
Density is defined as the mass per unit volume of a substance. The expression is given below:
Density =
We know the mass of the substance but the volume is unknown:
Volume of the brown sugar = l x bx h = 8x8x8 = 512cm³
Density of the brown sugar = = 0.0025g/cm³
