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:
Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.
Answer:
D) 1 iron(II), 2 chloride
Explanation:
Iron II chloride is the compound; FeCl2. It is formed as follows, ionically;
Fe^2+(aq) + 2Cl^-(aq) -----> FeCl2
The formation of one mole of FeCl2 involves the reaction one mole of iron and two moles of chloride ions. This means that in FeCl2, the ratio of iron to chlorine is 1:2 as seen above.
Therefore there is one iron II ion and two chloride ions in each mole of iron II chloride, hence the answer.
