The projectile is the bullet it's self. the chemicals create the explosion to project the bullet
Each mole of nitrogen produces 2 moles of ammonia.
One mole of gas occues 22.4 liters under STP.
Moles of ammonia = 100/22.4
= 4.46 moles
Moles of nitrogen required = 4.64/2
= 2.32 moles
Mass = moles x Mr
Mass of nitrogen = 2.32 x 28
= 64.96 grams
I would say the answer is C.
The solution to the problem is as follows:
<span>a)
C + O2 = CO2
Molar mass CO2 = 44 g/mol
3.67 g CO2 * 1 mol / 44 g =
=0.0834 mol CO2 = 0.0834 mol C
I hope my answer has come to your help. God bless and have a nice day ahead!

They look like gases plasmas have no fixed shapes or volume and are less dense tan solids or liquids
The question is incomplete. the complete question is:
A chemistry student needs 35.0 g of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of pentane is . Calculate the volume of pentane the student should pour out.Round your answer to 3 significant digits.
Answer: The volume of pentane the student should pour out is 55.9 ml
Explanation:
Density is defined as the mass contained per unit volume.
To calculate volume of a substance, we use the equation:
We are given:
Density of pentane =
Mass of pentane = 35.0 g
Putting values in above equation, we get:
(Conversion factor: )
Hence, the volume of pentane is 55.9 ml
