Explanation:

A substance burning in the presence of oxygen and leads to the formation of heat and light is called combustion.

Some important points about combustion are as follows:

  • Fuel should be present for burning.
  • Air should be present for the supply of oxygen.
  • There should be heat (or ignition temperature) to initiate the chemical reaction.

A balloon has a volume of 2.29 liters at a pressure of 100.0 kPa. If the pressure of the balloon is decreased to 83.5 kPa, what
Tanzania [10]

Answer: 2.74 litres

Explanation:

Given that,

Original pressure of balloon (P1) = 100.0 kPa

Original volume of balloon (V1) = 2.29 litres

New pressure of balloon (P2) = 83.5 kPa

New volume of balloon (V2) = ?

Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law

P1V1 = P2V2

100 kPa x 2.29 L = 83.5 kPa x V2

229 kPa•L = 83.5 kPa•V2

Divide both sides by 83.5 kPa

229 kPa•L/83.5 kPa = 83.5 kPa•V2/ 83.5 kPa

2.74 L = V2

Thus, the new volume of the balloon is 2.74 litres

How many moles of O2 molecules should be supplied to burn 1 mol of CH4 molecules in a domestic furnace?
Sati [7]
The combustion of 1 mole of methane (CH4) in a domestic furnace requires 2 moles of O2 molecules, assuming the combustion was complete or ideal. To solve this problem, use stoichiometry of the reaction's balanced chemical equation:

CH4 + 2O2 --> CO2 + 2H2O

The ratio of CH4 to O2 in terms of moles is 1:2. So 1 mole of CH4 needs 2 moles of O2.
