Consider the statement, “In a chemical reaction, atoms are neither created nor destroyed, only rearranged.” Why is this a statem
Karo-lina-s [1.5K]

Answer: The law of conservation of mass is reffering to the fact that energy cannot be created or destroyed. So when you speak about atoms not being created or destroyed it is the same thing. Unless you're talking about an atomic bomb where the atoms are split.

A sample of Ammonia gas at 650mmHg and 15 degree has a mass of 56.8g.calculate the volume occupied by the gas. Take N=14, H=1,R=
avanturin [10]

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 (PV = nRT).

650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.

650 \ mmHg \ * \ \frac{101kPa}{760 mmHg} = 86 \ kPa

P = 86kPa

T = 15°C + 273K = 288K

R (Gas constant) = 8.31 kj/mol  

Molar mass of Ammonia (NH_{3}) = (1 x 3) + (14) = 17g/mol

n (moles) = \frac{mass}{molar \ mass} = \frac{56.8}{17} = 3.34 mol

V = ?

Rearrange the equation to solve for Volume:

V = \frac{nRT}{P}

Substitute the values inside:

V = \frac{(3.34)(8.31)(288)}{(86)} = 93 L (rounded)

<u>Therefore 93 L of volume is occupied by the ammonia gas.</u>

<u></u>
