Answer:
Option c.
Explanation:
Convection - transfer of heat mode is that technique of transfer of heat in which heat and thermal energy can be transferred from one point to another point in the system by the random movement of the molecules of the fluid. This method of transfer of heat or the mechanism of transfer of heat by convection is the most dominant form of transfer of heat in gases and liquids.
Therefore, we can say that convection involves the transfer of heat as a result of the macroscopic and some random movement of the fluid molecules.

In region C the enzyme is saturated with substrate.
The fee of reaction whilst the enzyme is saturated with the substrate is the maximum charge of the response, Vmax. the relationship between the price of response and awareness of substrate relies upon the affinity of the enzyme for its substrate.
whilst all lively sites are occupied, the enzyme is saturated. At this saturation point, adding extra substrate makes no difference to the response rate.

<h2>
Answer:</h2>
44.06 g/mol
<h3>
Explanation:</h3>
We are given;
- Number of moles of unidentified gas as 1.674×10^-4 mol
- Time of effusion of unidentified gas 86.6 s
- Number of moles of Argon gas as 1.715×10^-4 mol
- Time of effusion of Argon gas is 84.5 s
We are supposed to calculate the molar mass of unidentified gas
<h3>Step 1: Calculate the effusion rates of each gas</h3>
Effusion rate = Number of moles/time
Effusion rate of unidentified gas (R₁)
= 1.674×10^-4 mol ÷ 86.6 s
= 1.933 × 10^-6 mol/s
Effusion rate of Argon gas (R₂)
= 1.715×10^-4 mol ÷ 84.5 sec
= 2.030 × 10^-6 mol/s
<h3>Step 2: Calculate the molar mass of unidentified gas</h3>
- Assuming the molar mass of unidentified gas is x;
- We can use the Graham's law of effusion to find x;
- According to Graham's law of diffusion;
But, Molar mass of Argon is 39.948 g/mol
Therefore;
Solving for X
x = 44.06 g/mol
Therefore, the molar mass of the identified gas is 44.06 g/mol

Explanation:
Mol is the amount of molecules in something. Mol are similar to donuts, if you have a dozen of something you have 12 of them. If you have a mol of Hydrogen gas you 6.02•10^23 molecules of Hydrogen gas. If you are taking a chemistry class you will probably receive questions involving converting grams to mol and vice versa.
Converting Grams to Mol:
grams of x•(1/molecular mass of x)
note: you can find molecular mass of x by looking at the masses of the elements you need to add up in the periodic table
Converting Mol to Grams:
mol of x•(molecular mass of x)
