Answer:
If the volume of the container is decreased by a factor of 2 the pressure is is increased by the same factor to 1664 torr.
Explanation:
Here we have Boyle's law which states that, at constant temperature, the volume of a given mass of gas is inversely proportional to its pressure
V ∝ 1/P or V₁·P₁ = V₂·P₂
Where:
V₁ = Initial volume
V₂ = Final volume = V₁/2
P₁ = Initial pressure = 832 torr
P₂ = Final pressure = Required
From V₁·P₁ = V₂·P₂ we have,
P₂ = V₁·P₁/V₂ = V₁·P₁/(V₁/2)
P₂ = 2·V₁·P₁/V₁ = 2·P₁ = 2× 832 torr = 1664 torr
First you find moles of HCl.
8.53gHCl(1 mol HCl/36.46gHCl)=0.234mol HCl
Then since molar it is mol/L you divide the number on moles of HCl by the amount of solution in L (0.372L).
Good luck!
Answer:
O A. A metal higher on the activity series list will replace one that is
lower.
Answer:
Explanation: Sodium has an atomic number of 11, so it has 11 protons. The atomic mass is 23, so there are 23 − 11 = 12 neutrons. The charge is +1, so there is 1 more proton than electrons, so there are 10 electrons
