If the.pressure exerted by a gas at [math]25^{\circ} \mathrm{C}[/math] in a volume of 0.044 L is 3.81 atm, how many moles of gas are present
Answer:
Error of parallax it usually occurs when the cylinder is above or below the eye level,and thus resulting in differences In reading the millimeters
Hello!
The pollution due to oxides of sulfur gets enhanced due to the
presence of :
- (a) particulate matter
- (b) ozone
- (d) hydrogen peroxide
∴ The correct option is : <u>(4) (a),(b),(d) only</u>
Partial pressure can be calculated from balanced equation as :
Partial pressure can be calculated from total pressure and mole fraction of a molecule. The equation of partial pressure is given as:
Mole fraction can be calculated from number of moles of different substances, that we can get from a balanced equation.
If a balanced equation is as follows:
aA+bB---->cP
Mole fraction of A will be =
And partial pressure of A will be:

The process by which gas changes to a solid is deposition.
