Answer:
The sodium nitrate is more economical
Explanation:
Hi, to compare this two options you need to determine the amount of nitrogen per 100 lb of both and then estimate its cost:
1) Sodium nitrate
This fertilizer has 30 % by weight of sodium nitrate:
The molecular weight of sodium nitrate:
So, this salt has 14 g of N per 85 g:
Cost per gram:
2) Ammonium sulfate
This fertilizer has 20 % by weight of ammonium sulfate:
The molecular weight of ammonium sulfate:
So, this salt has 14 g of N per 114 g:
Cost per gram:
Answer:
Crudeoil is a mixture and it comprises of compounds mostly hydri carbons i think
Answer:
either a car or a rock
Explanation:
because the rock can weigh more than the car , and vice-versa with the car weighing more than the rock
Acids are donors of protons (H+) and bases are acceptors of protons.
For example:
1) hydrochloric acid (HCl) in reaction with water give one proton to water and become chloride anion (Cl-).
2) ammonia (NH3) Is base, in reaction with water accepts one protone and become ammonium cation (NH4+).
