avogadros law states that under constant temp n pressure, volume of a gas is directly proportional to amount of gas
amount of gas1 = 352millimoles
amount of gas2 = 352+100 = 452millimoles
new vol = old vol x 452/352 = 25.2 x 452/352
= 32.4 mL
Answer:
Nitrogen
Oxygen
Argon
Carbon Dioxide
Methane
Ozone
Explanation:
N₂ accounts for 78% of the atmosphere.
O₂ accounts for 21% of the atmosphere.
Ar accounts for 0.9% of the atmosphere.
CO₂, CH₄, and O₃ only take up 0.1% of the atmosphere.
Answer:
I think its D. and A hopefully that's right
Answer:
there are 2.2 moles of Li in 15 grams of Li
The salt whose aqueous solubility will most likely to change the pH of the solution is CaF2(aq).
The pH of a salt solution depends on the nature of the acid and base that forms the salt.
- Salt of a weak acid and a strong base yields a basic solution
- Salt of a strong acid and a weak base yields an acidic solution
- Salt of a strong acid and a strong base yields a neutral solution.
Since HF is a weak acid, its salt CaF2 will be slightly basic when dissolved in water hence the pH of the solution is altered.
