Answer:

The red balloons have a biconcave disk structure, which is what is worded in the question seems to me a little wrong.

On the other hand, the elongated structure of muscle cells is due to a greater initial length in order to perform muscle contractions in a better way, or to perform their function at sea.

Something very important that the differences is that the red balloon does not have a nucleus (the muscle cell is multinucleated and has more mitochondrial load) and this structure is characteristic for being able to transport gases such as oxygen and disseminate them better in the body.

Explanation:

Red blood cells also have a shorter half-life than muscle cells, they are responsible for traveling throughout the body and renew their hemoglobin component after 120 days in the spleen.

On the other hand it is important to note that both work together when performing physical exercise, one donates oxygen and the other consumes it, considering that the muscle cell has more capacity to withstand hypoxic moments, that is why it supports lactic fermentations in anaerobic processes .

In summary, the red globule has this shape to act as gas transport, and the muscle cell to have a better start in contractile function.

The total quantity of heat evolved in converting the steam to ice is determined as  -12,928.68 J.

<h3>Heat evolved in converting the steam to ice</h3>

The total heat evolved is calculated as follows;

Q(tot) = Q1(steam to boiling point) + Q2(boiling point to ice) +Q3(freezing to -42 ⁰C)

where;

  • Q is heat evolved

Q = = mcΔθ

where;

  • m is mass,  (mass of water = 18 g/mol)
  • c is specific heat capacity,
  • Δθ is change in temperature

Q(tot) = 2(18)(2.01)(100 - 135) + 2(18)(2.01)(0 - 100) + 2(18)(2.09)(-42 - 0)

Q(tot) = -12,928.68 J

Thus, the total quantity of heat evolved in converting the steam to ice is determined as  -12,928.68 J.

A 10.0 g sample of an unknown liquid is vaporized at 120.0°C and 5.0 atm. The volume of the vapour is found to be 568.0 mL. The
Minchanka [31]

Answer:

molecular formula of liquid = C₈H₁₈

Explanation:

First we determine the empirical formula of the liquid:

Number of moles of each element present in the liquid = % mass / molar mass

For Carbon, (molar mass = 12.01 g/mol) : 84.2/12.01 =7.011 moles

For Hydrogen (molar mass = 1.01 g/mol) : 15.8/1.01 = 15.643

Simplest mole ratio of the elements, C : H  is given by:

C = 7.011/7.011 = 1.0

H = 15.643/7.011 = 2.23

Multiplying through with 5, C:H = 5:11

Therefore, empirical formula is C₅H₁₁

The molecular mass of the liquid is next determined:

Using PV = nRT to find the number of moles of the liquid present

P = 5.0 atm; V = 568.0 mL = 0.568 L; R = 0.082 L*atmmol⁻¹ K⁻¹; T = 273 + 120 = 393 K

n = PV/RT = (5*0.568)/0.082*393

n = 0.088 moles

Molar mass of liquid = mass/no of moles = 10.0 g/ 0.088 moles = 113.63 gmol⁻¹

Molecular formula = n(empirical formula)

Molar mass of empirical formula, C₅H₁₁ = 71 gmol⁻¹

n = molecular mass/empirical mass = 113.63/71 = 1.6

Therefore, molecular formula =  1.6*(C₅H₁₁) = C₈H₁₈
