Answer:
23.2L
Explanation:
The following were obtained from the question:
V1 = 22.5L
P1 = 748 mmHg
P2 = 725mmHg
V2 =?
The new volume can be obtained by doing the following:
P1V1 = P2V2
22.5 x 748 = 725 x V2
Divide both side by 725
V2 = (22.4 x 748) /725
V2 = 23.2L
The new volume is 23.2L

Answer:
When hydrogen is subjected to large enough pressure, it solidifies according to theory.
Explanation:
According to theory, when hydrogen molecules are subjected to enormous degree of pressure the molecules will solidify.
What happens here is that the hydrogen–hydrogen bonds in the hydrogen molecule will break apart and the molecules collapses into hydrogen atoms.
Hence, when hydrogen is subjected to large enough pressure, it solidifies according to theory.
Answer:
The rate of dissolution for a solid solute when cease of stirring is typically: B. It is decreased
Explanation:
The rate of dissolution for a solid solute decreases when you stop stirring it.
The answer is: Objects in the universe attract each other through gravitational force, depending on their masses and distance between the objects. I took a quiz with that question and got it right. Hope it helps :)
