Answer: The chemical formula for the formula given in the image is .
Explanation: There are many ways in which a model can be represented:
- Molecular Formula
- Ball and Stick formula
- Expanded Formula
- Condensed Formula
- Skeletal Formula
This molecule is represented by the Expanded Structural Formula and by seeing in the image we can count the number of each element present.
Number of Carbon atoms present = 4
Number of Hydrogen atom present = 9
Number of Oxygen atom present = 2
Correct representation for this will be .

Answer:
Directly
Explanation:
If V increases, then T must also increase to keep the same ratio.
If V decreases, then T must also decrease to keep the same ratio.
V and T are directly proportional, because a change in one always causes a change in the other and the changes are in the same ratio. The constant k is called the proportionality constant.
Answer:
a. Vₐ = 111.5282 + 1.29396m
b. For m = 0.100m; Vₐ = 111.6576
Explanation:
The partial molar volume of compound A in a mixture of A and B is defined as :
Where V is volume and n are moles of a.
a. As molality is proportional to moles of substance, partial molar volume of glucose can be defined as:
Vₐ = dV / dm = d(1001.93 + 111.5282m + 0.64698m²) / dm
<em>Vₐ = 111.5282 + 1.29396m</em>
b. Replacing for m = 0.100m:
Vₐ = 111.5282 + 1.29396×0.100
<em>Vₐ = 111.6576</em>
<em></em>
