What conditions cause deviations from the "ideal" gas?
select all that apply.
low temperatures
high temperatures
low pressure
high pressure

- low temperatures.

- high pressures.

Explanation:

Hello,

Based on the corresponding states principles, the conditions causing deviations from the ideal conditions (no molecules collisions and constant p-T-v relationship) are:

- low temperatures.

- high pressures.

As long as such conditions promote the molecules collisions and nonlinear p-T-v relationships simulated via cubic EoS or more sophisticated methods.

Best regards.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
