Answer: The pressure inside the bag of potato chips in Pascal's is 109
Explanation:
Pressure of the gas is defined as the force exerted by the particles on the walls of the container. S.I unit of pressure is pascal.
Thus units of pressure can be mm Hg or atmosphere or bar or Pascal.
Given : Pressure inside the bag is the same as atmospheric pressure at the factory = 0.82 mmHg
Pressure 760 mm Hg = 101325 Pa
0.82 mm Hg =
Thus the pressure inside the bag of potato chips in Pascal's is 109
Answer: 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal
Explanation:
To calculate the moles :
The balanced chemical equuation is:
According to stoichiometry :
4 moles of produce == 2 moles of
Thus 0.556 moles of will produce=
of
Mass of
Thus 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal.
