It might me b but I am not sure
Lol, onions. Onions produce a chemical irritant called synpropanerhial-S-oxide.
Mass, charge, and energy are conserved, no matter how much volume of
space they may be spread through either before or after the reaction.
Concerning density ...
Think about the fascinating classroom demonstration where the teacher
drops a tiny pellet of sodium into a glass of water. The sodium gets very
excited, and it skates and skitters around on the surface of the water,
faster and faster, and eventually it explodes. All the girls in the class
scream, while the guys are just sitting there and staring at the cloud
of steam that's rising from the glass of water. The whole point here
is that the density of the steam is much different from the density of
either the water or the sodium that reacted to create it. The density
is not conserved.
1 mole of nitric acid produce 1 mole of ammonium nitrate.
moles in 5000 kg of ammonium nitrate :
( molecular mass of ammonium nitrate is 80 gm/mol )
So, number of moles of nitric acid required are also 62500 moles.
Mass of 62500 moles of nitric acid :
Hence, this is the required solution.
Answer:
53.5g of NH4Cl
Explanation:
First, we need to obtain the number of mole of NH4Cl. This is illustrated below:
Volume = 0.5L
Molarity = 2M
Mole =?
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 2 x 0.5
Mole = 1mole
Now, let us convert 1mole of NH4Cl to gram. This is illustrated below:
Molar Mass of NH4Cl = 53.5g/mol
Number of mole = 1
Mass =?
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass = 1 x 53.5
Mass = 53.5g
Therefore, 53.5g of NH4Cl is contained in the solution.
