Answer: B. Magnification.

Yes you are absolutely right. Although Enlargement and Magnification have similar meanings, the correct term used for objects that get larger in a microscope is called magnification. Magnification in a microscope refers to the enlargement of the object that is being observed in the microscope.

Kobotan [32]

Answers are:
Catabolism:
- generally exergonic (spontaneous): In this reactions energy is released.
- convert NAD+ to NADH. Electrons and protons released in reactions are attached to NAD+.
- generation of ATP. ATP is synthesis from ADP.
- convert large compounds to smaller compounds. Foe example starch to monosaccaharides.
Anabolism:
- convert NADPH to NADP+. Protons and electrons are used to make chemical bonds.
- convert small compounds to larger compounds.

What is the molarity of an intravenous glucose solution prepared from 108 g of glucose in 2.0 L of solution? 0.018 mol/L 0.30 mo

scZoUnD [109]

Answer:

0.30 mol/L

Explanation:

Mass = 108 g

Molar mass of glucose = 180.156 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{108\ g}{180.156\ g/mol}$

$Moles= 0.5995\ mol$

Given Volume = 2 L

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

$Molarity=\frac{0.5995}{2}$

Molarity = 0.3 mol/L

If 0.025 gram of Pb(NO3)2 is dissolved in 100. grams of H2O, what is the concentration of the resulting solution, in parts per m

anastassius [24]

Answer:

249.94ppm

Explanation:

Given parameters:

Mass of Pb(NO₃)₂ = 0.025g

Mass of water = 100g

Unknown:

Concentration of solution in ppm = ?

Solution:

Concentration in parts per million gives the amount of solute found in a million units of the solution. They are desirable for expressing very small amount of solutes in a large solution. For example, the level of arsenic in the soil.

Concentration in ppm = $\frac{amount of solute}{amount of solution} x 10^{6}$

A solution is made up of solute and solvent. The solvent here is water.

mass of solution = mass of solute + mass of solvent = 0.025 + 100 = 100.025g

Concentration in ppm = $\frac{0.025}{100.025} x 10^{6}$ = 249.94ppm
