Answer:

c. The circulatory system moves oxygen throughout the body that is brought in by the respiratory system.

Explanation:

The circulatory system delivers oxygen and nutrients to cells and takes away wastes.

The respiratory system is the network of organs and tissues that help you breathe.

So, of the options, option c is correct.

Hope this helps!

Where could you find hydrocarbon chains?

ser-zykov [4K]

Answer: Most Hydrocarbon chains are found in petroleum, coal, and natural gas. First of all, a hydrocarbon chain is a molecule that consist of entirely hydrogen and carbon.

Explanation: There are many types of hydrocarbon chains, which can be found in alkanes, alkynes, arenes, alkenes, and cycloalkanes. Natural rubber for instance is a hydrocarbon that primarily consists of alternating single and double bonded carbons.

The common Eastern mole, a mammal, typically has a mass of 83 g, which corresponds to about 8.3 moles of atoms. (A mole of atoms

Alchen [17]

Answer:

1.6605 × 10⁻²³ g / atom , 9.99 amu

Explanation:

Atoms present in 1 mole = 6.022 × 10²³ atoms

Given that

Moles of common Eastern mole = 8.3 moles

So,

Atoms in 8.3 moles are:

8.3 moles = 6.022 × 10²³ × 8.3 atoms

Also,

Average mass = Mass of the sample / Number of atoms

Mass of sample = 83 g

Average mass = 83 g / 6.022 × 10²³ × 8.3 atoms = 1.6605 × 10⁻²³ g / atom

In amu :

1 amu = 1.66 × 10⁻²⁴ g / atom

So,

Average mass = 1.6605 × 10⁻²³ / 1.66 × 10⁻²⁴ amu = 9.99 amu

On hot days, you may have noticed that potato chip bags seem to "inflate", even though they have not been opened. If I have a 25

Slav-nsk [51]

The new volume of the bag will be 789.5 mL.

Explanation:

As per the Charles law, at constant pressure the volume of the gas is directly related to its temperature in Kelvin (K). That is as the temperature increases, the gas expands and vice-versa.

$$\frac{V1}{T1} = \frac{V2}{T2}\\$

V1 = 250 ml

V2 = ?

T1 = 19° C

T2 = 60° C

Now we have to rewrite the equation to get the new volume as,

V2 = $$\frac{V1T2}{T1}$

= $$\frac{250\times60}{19}$

= 789.47 ≈ 789.5 ml.

So the new volume of the bag will be 789.5 mL.

If you obtained 2.50 moles of CuSO4 from the reaction of CuO and H2SO4, but the theoretical yield was 3.19 moles, what was the p

IceJOKER [234]

Answer:

78.4%

Explanation:

Just as context, write the chemical equation and the mole ratios

1) Balanced chemical equation:

CuO (s) + H₂SO₄ (aq) → CuSO₄ (aq) + H₂O (l)

2) Therotetical (stoichiometric) mole ratios:

1 mol CuO : 1 mol H₂SO₄ : 1 mol CuSO₄ : 1 mol H₂O

You can calculate the percent yield from the amount of CuSO₄ obtained and the theoretical yield

3) Percent yield

Definition:

Percent yield = (actual yield / theoretical yield)×100

Theoretical yiedl (given): 3.19 moles CuSO₄

Actual yield (given): 2.50 moles CuSO₄

Calcualtion:

Substitute the values in the formula:

Percent yield = (2.50 moles CuSO₄ / 3.19 moles CuSO₄)×100 = 78.4%
