Answer:
The new pressure is 53.3 kPa
Explanation:
This problem can be solved by this law. when the volume remains constant, pressure changes directly proportional as the Aboslute T° is modified.
T° increase → Pressure increase
T° decrease → Pressure decrease
In this case, temperature was really decreased. So the pressure must be lower.
P₁ / T₁ = P₂ / T₂
80 kPa / 300K = P₂/200K
(80 kPa / 300K) . 200 K = P₂ → 53.3 kPa
The mass of gas A is 11.56. i got this answer by 0.68 multiplied by 17. because in this problem the key word is times.
Answer:
NaHCO3 → H2O + CO2 + Na2CO3
Explanation:
Answer:
Is [h] really [H]? What characteristics are mentioned?
Explanation:
A high [H} means high acid concentration.
Answer:
1290 atm
Explanation:
P1V1=P2V2
P2= (P1V1)/V2
P2=(2.15 atm * 750 mL)/(1.25 mL)
P2=1290 atm
