Infer Why is a mechanism needed to remove carbon
dioxide gas from your cells?

Answers

Answer 1

Answer:

Because too much Carbon Dioxide can kill us.

Explanation:

Answer 2
^^ what he said. carbon dioxide, if there is enough in our body, can eventually kill us. it can be seen with deep sea divers, which after several continuous deep dives can have a excessive amount of carbon dioxide in there body to a lethal amount, having to force them into special rooms which allows the deep sea divers to decompress slowly and remove a good bit of the dioxide to lower the amount in them.

What is the relationship between the atomic mass of an element and a mole of the element atoms?

Answers

The mass of a pure substance represents a specific number of pure substance 'molecules', as defined by molecular weight. The relative atomic mass (atomic weight) in grams/mole (g/mol) is the molar mass of a substance, which means it is the mass of one mole of that substance.

A) Devices that transfer kinetic energy have what for their source of power?
B) Why is burning kerosene for energy not the best solution?
C) Explain why there is not one right why of obtaining energy when it is not available

Answers

Answer:

A) Devices that transfer kinetic energy have a source of power that is in motion

Kinetic energy is the energy in motion, as such, a device that transfers kinetic energy transfers the energy the power source has into other energy forms

B) Kerosene does not easily cold start like diesel which can burn after compression

C) The first law of thermodynamics states that energy is conserved and it can neither be created nor destroyed, but can be changed from one form to another.

Therefore, when energy is not available in a given location or body, it cannot be obtained from that body or location

How many moles do you have if you have 8.03 x 1023 atoms of oxygen?

Answers

Answer:

The answer is 1.33 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{8.03 \times {10}^{23} }{6.02 \times {10}^{23} } \\ = 1.33388704...[/tex]

We have the final answer as

1.33 moles

Another physical property  I chose for the bowling ball was shape, The reason I chose shape was because the bowling ball is circle, the actual name for a 3-D circle is sphere. The last physical property for a bowling ball is color because mostly all bowling balls have color for example the one in the picture it is red with a little bit of pink, there is many different bowling balls that have different color different hardness but NOT different  shape. That is the physical properties of a bowling ball.

Answers

Answer:

Cl^- = 5.75

K^+ = 7.75

Explanation:

Now let us calculate the effective nuclear charge four K^+ and Cl^- from Slater's rule.

Given that Cl^- and K^+ has electronic configuration of; [Ne] 3s2 3p6 (they are isoelectronic species)

We compute S as follows;

For n - 2 level, S= 1

For n - 1 level, S= 0.85

For ns,np level S= 0.35

Note: S= screening or shielding constant

1s2, S=2 ×1 = 2

2s2 2p6, S= 8×0.85 = 6.8

3s2 3p6, S= 7 × 0.35 = 2.45

The electron under study is not considered hence seven out of eight electrons in the shell are considered

Hence

S= 2 + 6.8 + 2.45 = 11.25

Since Cl^- has 17 electrons;

Zeff(Cl^-) = 17 - 11.25 = 5.75

For K^+

Zeff = 19 - 11.25 = 7.75

Ethanol is a primary alcohol that is ethane in which one of the hydrogens is substituted by a hydroxy group.

Ethanol is an important industrial chemical; it is used as a solvent, in the synthesis of other organic chemicals.

Ethanol produced either by fermentation or by synthesis is obtained as a dilute aqueous solution and must be concentrated by fractional distillation.
