1.02 moles of the gas is present in the sample.
The conditions in which the gases deviate from ideal behavior is high pressure and low temperatures.
Correct option is 2.
Explanation:
Data given:
volume of the gas = 31.2 litres
temperature of the gas = 28 degrees or 301.15 K
pressure of the gas = 82.6 kPa or 0.815 atm
R (Gas constant) = 0.0820 Latm/moles K
number of moles =?
From the ideal gas law, we have
PV = nRT
rearranging the equation:
n = 
n = 
n = 1.02 moles
At high pressure and low temperature an ideal gas deviates from ideal behaviour. Under high pressure the gas molecules get closer to each other and intermolecular force acts on them as molecules attract each other while in ideal case gas has no attractions in its molecules.
Answer:
0.090 J/(mmol·°C) × (1000 mmol/mole × 1 kJ/(1000 J)) = 0.090 kJ/mole
Explanation:
The unit of conversion from kilo-Joules to Joules is given as follows;
1000 Joules = 1 kilo-Joule
The unit of conversion from milimoles to moles is given as follows;
1000 milimoles = 1 Mole
Therefore, we have
The value of the given expression is 0.090 J/(mmol·°C) × 1000 mmol/mole × 1 kJ/(1000 J) = 0.090 kJ/mole
0.090 J/milimole = 0.09 kJ/mole.
I believe the answer is B. Magnesium bromide , if I helped..... You're welcome
Answer:
Explanation:
Depending upon the relative arrangements of XandY X a n d Y , the square planar molecule AX3Y A X 3 Y shows only the following structure: Hence, only one structure is possible for a square planar molecule with a formula of AX3Y A X 3 Y .
