Explanation:
P = 27.8atm
At what temperature will 5.00 g of Cl2 exert a pressure of 900. mmHg at a volume of 750.
Answer: 68.6 mL
Explanation:
We need to use the equation M1V1=M2V2. Molarity's units are in L so we need to convert the 50 ml into L (divide by 1000).
.05(.298)=(x)(.2173)
x = .068 L
to convert to mL we multiply by 1000
.068*1000=68.6 mL
Answer:
The correct answer is option (B) Two molecules of H2 and a molecule of O2 must collide at one time
Explanation:
2H2(g) + O2(g) → 2 H2O(g)
2 1 2
Considering the given reaction, for water molecule to be form, two molecules of hydrogen and one molecule of oxygen must collide at the same time. The product obtained from the collision is two molecules of water as steam. 2 H2O(g)
