A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charge.
I'm not sure but for those who can help:
<u>Skeleton equation</u>: It's neutralization because acid+base.
HCl + NaOH => H2O + NaCl
Answer:
The first thing we have to do is change and state all the units so that we can use our ideal gas law equation (
).
650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.

P = 86kPa
T = 15°C + 273K = 288K
R (Gas constant) = 8.31 kj/mol
Molar mass of Ammonia (
) = (1 x 3) + (14) = 17g/mol
n (moles) =
3.34 mol
V = ?
Rearrange the equation to solve for Volume:

Substitute the values inside:
V = 
<u>Therefore 93 L of volume is occupied by the ammonia gas.</u>

The curved top of a liquid is the meniscus
