Question 1

What is an ideal gas

Answer 1

It assumed that there is no attractive or repulsive forces

Question 2

There are two exceptions to applying the ideal gas law

Answer 2

We can’t apply the ideal gas law on gases with law temperatures and high pressure

Question 3

Compare between the real and ideal gas in
1 volume
2 attract and repel
3- collision

Answer 3

Ideal gas : doesn’t have a volume - don’t attract or repel - have elastic collosion.

Real gas : have its own volume - attract each other - have collision that are not elastic

Question 4

What is the ideal gas law

Answer 4

The ideal gases don’t attract or repel between the molecules

Question 5

What is the rule applied to the ideal gas?

Answer 5

PV=nRT

Question 6

What does each of the symbols represents
PV=nRT

Answer 6

P pressure 1 atm = 760mmHg = 101350Pa
V volume L
n number of moles mol
R gas Constance ( 0.082057) atm.L/ mol.K
T temperature kelvin

Question 7

In this equation with is the excess and which is the ideal gas
Mg(s) + 2HCl (aq) = MgCl2(aq) + H2(g)

Answer 7

Excess is HCl
Limiting is Mg
Ideal gas H2

Question 8

If you have n trials what is the average of R?

Answer 8

R average = the sum of the all values of R / n
