Answer:
c. The average kinetic energies of the two gases are the same.
Step-by-step explanation:
A major postulate of the Kinetic Molecular Theory is that the average kinetic energies of all gases are the same at the same temperature.
a. is <em>wrong</em>. N₂ and O₂ are different elements with different molar masses.
b. is <em>wrong</em>. According to Avogadro's Law, the partial pressure varies directly as the number of moles. There are twice as many molecules of O₂ as of N₂, so p(O₂) = 2p(N₂).
Answer:
1200 mL
Explanation:
Step 1:
Data obtained from the question. This includes the following:
Initial volume (V1) = 400 mL.
Initial pressure (P1) = 600 mmHg.
Final volume (V2) =..?
Final pressure (P2) = 200 mmHg
Step 2:
Determination of the final volume i.e the new volume of the gas.
Considering the question given, we understood that the temperature is constant. Therefore the gas is obeying Boyle's law. Using the Boyle's law equation, the new volume is obtained as follow:
P1V1 = P2V2
600 x 400 = 200 x V2
Divide both side by 200
V2 = (600 x 400) /200
V2 = 1200 mL
Therefore, the new volume of the gas is 1200 mL.
Resultant aqueous solution of a hydrogen oxalate salt is basic in nature.
<h3>What is pH?</h3>
pH scale is used to determine the acidity, basicity or neutral nature of any solution.
- Values from 0 to 6.9 shows the acidity.
- 7 shows the neutrality.
- And 7.1 to 14 shows the basicity.
Chemical equation for the given salt in an aqueous solution will be shown as:
NaHC₂O₄ + H₂O → NaOH + H₂C₂O₄
From the equation it is clear that reaction produces-
- NaOH which is a strong base and
- H₂C₂O₄ oxalic acid which is a weak acid.
So that resultant solution is basic in nature.
Hence the aqueous solution of salt is basic.

Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm are haploid, which means they each contain one set of chromosomes; upon fertilization, they will combine their genetic material to form a zygote that is diploid, having two sets of chromosomes.
Hope this helped
Answer:
mL * L²
Explanation:
The question in t his problem is to calculate the units of the final answer.
The units in the numerator is mol, ml and L.
The unit in the denominator is mol/L
This leads us to;
Numerator / Denominator = mol * mL * L / (mol / L )
The final units is mL * L²
