Blood has a mass-volume percent of NaCl of 0.9%. What mass (g) of NaCl is present in a liter of blood

Answers

Answer 1

The mass (g) of NaCl that is present in a liter of blood is 0.347g.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the decimal mass-volume of the substance by its molar mass.

According to this question, Blood has a mass-volume percent of NaCl of 0.9%. This means that 0.9/100 = 0.009g of NaCl is present in each 100g of blood.

Molar mass of NaCl = 23 + 35.5 = 38.5g/mol

Mass of NaCl in a liter of blood = 38.5 × 0.009

Mass of NaCl in a liter of blood = 0.347g of NaCl.

Therefore, The mass (g) of NaCl that is present in a liter of blood is 0.347g.

Calculate the solubility of copper (II) iodate in 0.16 M copper (II) nitrate. Ksp* is 7.4x10-8 M3. *You should know that the Ksp must refer to the copper iodate because all nitrate compounds are soluble and strong electrolytes!

Answers

Answer:

solubility in presence of 0.16M Cu(IO₃⁻)₂ = 3.4 x 10⁻⁴M*

Explanation:

        Cu(IO₃⁻)₂ ⇄           Cu⁺²          +   2(IO₃⁻)        

C(i)    ----------                0.16M                 0M

ΔC    ----------                   +x                   +2x

C(f)    ----------      0.16 + x ≅ 0.16M*        2x

Ksp = [Cu⁺²][IO₃⁻]²

7.4 x 10⁻⁸M³ = 0.16M(2x)² = 0.64x²

x = solubility in presence of 0.16M Cu(IO₃⁻)₂ = SqrRt(7.4x10⁻⁸M³/0.64M²)

= 3.4 x 10⁻⁴M*

*Note: This is consistent with the common ion effect in that a reduction in solubility is expected. The normal solubility of Cu(IO₃⁻)₂ in pure water at 25°C is ~2.7 x 10⁻³M.

In the malate-aspartate shuttle, _____ is reduced to _____ in the cytosol. oxaloacetate; malate aspartate; malate malate; aspartate malate; oxaloacetate aspartate; oxaloacetate

Answers

The malate-aspartate shuttle enables oxidative phosphorylation by allowing electrons to be moved across the inner membrane in the mitochondrion during glycolysis in eukaryotes.

In this malate-aspartate shuttle, oxaloacetate is reduced to malate in the cytosol.

During this biochemical system process, the cytosolic malate dehydrogenase which is the primary enzyme present in this shuttle system catalyzes the reaction of oxaloacetate and NADH to produce malate and NAD in the cytosol. This system enables oxidative phosphorylation in eukaryotes.

Knowing about the greenhouse effect we have that what intensifies this effect is an increase in gases in the atmosphere that absorb heat.

What is the greenhouse effect?

Greenhouse effect is a natural atmospheric phenomenon responsible for the maintenance of life on Earth. Without the presence of this phenomenon, the temperature on Earth would be very low, around -18ºC, which would make the development of living beings impossible.

Thus, the main cause of the greenhouse effect is industrialization. Due to this process, the burning of fossil fuels has intensified in recent centuries. The main products of the combustion reaction of these reagents are the gases mentioned above as the main ones for the greenhouse effect.

Convert 4.0 moles of krypton into liters of krypton.

Answers

Answer:

4.0 moles of krypton converts to 89.6L.

Explanation:

To convert moles to liters, remember that at standard temperature and pressure (STP), 1 mole is equal to 22.4 liters. Multiply your mole value - in this case, 4.0 - by the molar volume constant, 22.4L, to convert moles into liters. 4.0 x 22.4 is equal to 89.6, thus your answer is 89.6L.

We can check this by dividing 89.6 by 4.0, which will give us the molar volume constant 22.4L, proving that this answer is correct.

O Gay-Lussac's law, by seeing how changes in temperature affect the pressure of the gas

Answers

It’s gay-lussacs law by seeing how changes in tenet arise affect the volume of gas I think

The chemist is most likely investigating Gay Lussac's law. To study the changes in temperature affect the pressure of the gas when a fixed amount of gas is heated in a sealed glass container. Therefore, option (D) is correct.

What is Gay Lussac's law?

Gay-Lussac's law states that when the volume of the gas is kept constant the pressure of a gas is directly proportional to the absolute temperature.

The mathematical expression of Gay Lussca's law can be written as follows:

P/T = k

It can be also represented as the pressure being directly proportional to the temperature of the gas.

P ∝ T                    (where V volume of gas is constant)

or

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]

Where P₁ and T₁ are the initial temperature and pressure of the gas. The P₂ and T₂ are the final temperature and pressure of the gas.

As the container is sealed on heating the volume of the gas will not change.  On increasing the temperature the molecules of the gas acquire more and more kinetic energy. So the pressure of the gas will increase.

Therefore, the chemist is investing the Gay-Lussac's law by noticing how changes in temperature affect the pressure of the gas.

Answer:

Plant cells and animal cells are both eukaryotic cells. They both have a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, cytoskeleton and cell membrane. Only plants cells have a vacuole, cell wall and chloroplast, while animal cells have cilia, centrioles and lysosomes which plant cells don't usually have. Because of their cell walls plant cells are in rigid rectangular shapes while animal cells have looser round shapes. The main difference in their functions is that animals don't produce their own food while plan cells do.
