0.091 moles are contained in 2.0 L of N2 at standard temperature and pressure.
Explanation:
Data given:
volume of the nitrogen gas = 2 litres
Standard temperature = 273 K
Standard pressure = 1 atm
number of moles =?
R (gas constant) = 0.08201 L atm/mole K
Assuming nitrogen to be an ideal gas at STP, we will use Ideal Gas law
PV = nRT
rearranging the equation to calculate number of moles:
PV = nRT
n = 
putting the values in the equation:
n = 
n = 0.091 moles
0.091 moles of nitrogen gas is contained in a container at STP.
Answer:
the answer is nitrogen and rubidium (C)
Explanation:
ionic bonds only form between metals and non-metals
Answer:
a,d,e
Explanation:
its a,d, and e because clean air keeps us alive and other organisms need it to stay alive
Answer:
Immiscible
Explanation:
Immiscible is the term that is used to refer to a mixture of liquids which can separate into distinct layers when left undisturbed. This usually comes to play when a polar solvent such as water is mixed with a non polar solvent such as kerosene.
These two liquids can be made to separate from each other using the method of separatory funnel
