Explanation:
The kinetic theory of gases is basically used to explain the behavior of gases.
Some of the assumptions of the theory is as follow:
- A gas is composed of large number of identical molecules at different speeds.
- The space occupied by the gas molecules themselves are negligible compared to the volume of the space they occupy.
- The molecules are independent of each other and the force of attraction and repulsion between them are negligible.
- The molecules collide elastically with one another and with the walls of the container.
- The temperature of gas is a measure of their average kinetic energy.

Answer:
A. Solid aluminum oxide and solid iron
Explanation:
The reaction equation is given as:
2Al + Fe₂O₃ → Al₂O₃ + 2Fe
The species on the left hand side are the reactants
Those on the right hand side of the expression are the products.
The products are:
Al₂O₃ and Fe
These are solid aluminum oxide and solid iron
The answer is D because for light 3 to function switch d does not have to turn on
Answer:
34.8 moles of CO₂ are produced
Explanation:
This is the reaction:
1C₅H₁₂ + 8O₂ → 6H₂O + 5CO₂
Ratio is 1:5. We make a rule of three
1 mol of pentane can produce 5 moles of CO₂
Then, 6.96 moles of pentane may produce (6.96 .5) / 1 = 34.8 moles
The colour of copper sulphate solution is blue
