CH3OCH3 and C2H5OH are isomers. They have same molecular formula. But with another formation.
Answer:
the volume should be in cubic cm so I assumed that you wanted to write the same . then the answer is 5489.07 kg/m^3
Answer:
Sand has less specific heat than water.
Explanation:
Specific Heat is amount of heat needed per unit mass, to raise temperature by 1 degree celsius.
More specific heat means more heat energy needed to increase temperature. It implies - more time needed to absorb heat, increase temperature; and also more time needed to lose its heat.
Less specific heat means less heat energy needed to increase temperature. It implies - less time needed to absorb heat, increase temperature; and also less time needed to lose its heat.
Sand has less specific heat than water. So, it needs less heat absorption to increase temperature by per unit (celsius) ; than water. Hence, same level of heat to both sand & water ; increase temperature of sand more than water, & make it more hot.
The molarity of the diluted solution is 0.33 M
From the question given above, the following data were obtained:
Molarity of stock solution (M₁) = 0. 5 M
Volume of stock solution (V₁) = 100 mL
Volume of diluted solution (V₂) = 100 + 50 = 150 mL
<h3>Molarity of diluted solution (M₂) =? </h3>
The molarity of the diluted solution can be obtained by using the dilution formula as illustrated below:
<h3>M₁V₁ = M₂V₂</h3>
0.5 × 100 = M₂ × 150
50 = M₂ × 150
Divide both side by 150
M₂ = 50 / 150
<h3>M₂ = 0.33 M</h3>
Therefore, the molarity of the diluted solution is 0.33 M

Answer:
Option B, When the cell needs to move a compound against its concentration gradient.
Explanation:
A cell uses active transport when it has to transport substances against the concentration gradient across its membrane.
In active transport additional energy is used (generally provided by energy molecules like ATP) to push the substance across any membrane from low concentration side to high concentration side.
Option B is correct
