Explanation:
Mg₃N₂ is the formula of magnesium nitride.
The Texas City Refinery explosion occurred on March 23, 2005, when a hydrocarbon vapor cloud was ignited and violently exploded at the ISOM isomerization process unit at BP's Texas City refinery in Texas City, Texas, killing 15 workers, injuring 180 others and severely damaging the refinery.
Answer:
The volume of the vessel is 250 L
Partial pressure of hydrogen = 189 torr
Explanation:
Using Boyle's law
Given ,
V₁ = 20.0 L
V₂ = ?
P₁ = 25 atm
P₂ = 2 atm
Using above equation as:
<u>The volume of the vessel is 250 L.</u>
According to Dalton's law of partial pressure:-
So, according to definition of mole fraction:
Also,
Mole fraction of H₂ = 1 - Mole fraction of He = 1 - 0.75 = 0.25
So,
Total pressure = 756 torr
Thus,
<u>Partial pressure of hydrogen = 189 torr.</u>
Answer:
B.
Explanation:
Gravity acts on all masses equally, even though the effects on both masses.

Answer:
The rate of the forward reaction is equal to the rate of the reverse reaction
Explanation:
Equilibrium is a condition in which the net force for change is zero.
In chemistry, equilibrium exists when reactant concentrations in a reaction are not changing. This condition means the reaction proceeding left to right in the reaction equation is producing products at the same rate those products are being used up by the reaction proceeding right to left. In short, the rate of the forward reaction is equal to the rate of the reverse reaction.
