What mass of glucose (C6H12O6) should be dissolved in 12. 0 kg of water to obtain a solution with a freezing point of -5. 8 ∘C?.
Answer:
6.7 kg
Explanation:
(0) - (-5.8)= 5.8ºC
5.8 / 1.86 = 3.12 m C6 H12 O6
The molar mass of C6 H12 O6 is: 180.156 g/mol
3.12 * 12 kg * 180.156 g/mol = 6,745.041 g = 6.7 kg.
The mass of glucose solute dissolved in the solution is 6.739 Kg.
Recall that;
ΔT = K m i
ΔT = Freezing point depression
K =Freezing point depression constant = 1.86°C/mol
m = molality of the solution
i = Van't Hoff factor = 1 (molecular solution)
We have to find the freezing point depression from;
Freezing point depression = Freezing point of pure solvent - Freezing point of solution
Freezing point of pure water = 0°C
Freezing point of solution = -5. 8 ∘C
Freezing point depression = 0°C - (-5. 8 ∘C) = 5. 8 ∘C
Now;
m = ΔT/K i
m = 5. 8 ∘C/ 1.86°C/mol × 1
m = 3.12 m
But molality = number of moles of solute/mass of solvent in Kg
Molar mass of solute = 180 g/mol
Let the mass of solute be m
3.12 = m/180/12
3.12 = m/180 × 12
m = 3.12 × 180 × 12
m = 6739 g or 6.739 Kg

Answer:

Explanation:
Pollutants mixed with water pass through permeable layers above the aquifer.
What is Groundwater?
Water that is found underground in saturated regions beneath the surface of the earth is known as groundwater. The water table is the term for the saturated zone's upper surface.
Contrary to popular perception, underground rivers are not created by groundwater. Similar to how water fills a sponge, it fills the pores and cracks in subterranean materials like sand, gravel, and other rock.
Rock materials are referred to as aquifers if groundwater flows naturally out of them or if it can be pumped out of them. One of the most significant natural resources for the country is groundwater, which is found in aquifers beneath the Earth's surface.
Therefore, Pollutants mixed with water pass through permeable layers above the aquifer.

Energy released by the electron transport chain is used to pump h+ into which location in eukaryotic cells?.
Answer:
Energy released by the electron transport chain is used to pump H+ into the mitochondrial intermembrane space - Option D-.
Explanation:
There exist three proteinic complexes immersed in the internal mitochondrial membrane. These complexes have the electron transporters and the enzymes necessary to catalyze the electron transference from one transporter to the other. In complexes, I and III released energy by electrons provokes changes in membrane transport protein conformation. These changes make possible the protons transport against their concentration gradient, going from the mitochondrial matrix toward the intermembrane space. The protons concentrations difference between the matrix and the intermembrane space represents released energy.

Find the measure of a negative angle coterminal with 95°.
The measure of a negative angle coterminal with 95° are for any integer n 95° – (1,080n)°. Thus, option (b) is correct.
What is coterminal?Angles in common position (angles with the starting side on the positive x-axis) that have a shared terminal side are referred to as coterminal angles. It's as easy as subtracting or adding 360° or 2 to each inclination, depending on whether it's measured in degrees or trigonometric functions. There are an endless amount of coterminal angles to be discovered.
The measure of a negative angle coterminal with 95°
Ф + 360 n
n is any integer (negative or positive)
Ф = 95°,
- 3n is an integer,
The co-terminal angles of 95° are,
= 95° + 360° (-3n)
= 95° - (1080 n)° ; for any integer n.
As a result, the measure of a negative angle coterminal with 95° are for any integer n 95° – (1,080n)°. Therefore, option (b) is correct.

Explanation:
formula:
mass - moles = mass given ÷ molar mass
R.M.M of CO2 = 32 + 6 = 38
Molar mass of CO 2 = 38g (recall that r.m.m = molar mass)
38g of CO2 will produce 1 mole

If and cx = 5 units, what is dz? 2 units 3 units 4 units 5 units.
Based on the calculations, the magnitude of side DZ is equal to 4 units.
How to calculate the magnitude of DZ?From the diagram, we can deduce that CD is parallel to XZ and as such, triangle XYZ is similar to Triangle YCD. Thus, the ratio of their corresponding side lengths are equal.
By applying the similarity condition, we have:
XY/CY = ZY/YD
(XC + CY)/CY = (DZ + DY)/DY
Substituting the given parameters into the formula, we have;
(5 + 25)/25 = (DZ + 20)/20
30/25 = (DZ + 20)/20
600 = 25DZ + 500
25DZ = 600 - 500
25DZ = 100
DZ = 100/25
DZ = 4 units.
