Answer:
D. Air pressure lowers the temperature of the liquid molecules.
Electron, because they’re about 1/2000 the mass of a proton or nuetron
Question 1 answer: A
Question 2 answer: H
Question 3 answer: J
Question 4 answer: T
Answer:
A. There was still 140 ml of volume available for the reaction
Explanation:
According to Avogadro's law, we have that equal volumes of all gases contains equal number of molecules
According to the ideal gas law, we have;
The pressure exerted by a gas, P = n·R·T/V
Where;
n = The number of moles
T = The temperature of the gas
R = The universal gas constant
V = The volume of the gas
Therefore, given that the volumes and number of moles of the removed air and added HCl are the same, the pressure and therefore, the volume available for the reaction will remain the same
There will still be the same volume available for the reaction.
