. Guillermo was finding it difficult to walk up the steps to his family’s apartment. His doctor thinks that his cells might not
morpeh [17]

Answer:

Because oxygen is the combustion  fuel and glucose  is the substrate needed for synthesis of energy as ATPs during cellular respiration.Therefore Guillermo lacks enough energy as ATPs in her  body cells, especially skeletal muscles cells to complete the task of ascending the s steps.

For all the mitochondrial in cells(sites of energy production)   to receive needed glucose,and other metabolites needed for  energy synthesis; an efficient transport system is needed, so that  these materials   are available  immediately, in required amount. This system is called circulatory system.

And for the the supply of combustion fuel (oxygen) needed for the completion of the ATP synthesis mechanisms;  respiratory systems which  convey oxygen from the external environments to the circulatory system through breathing mechanisms, for distribution is needed.

Thus the  doctor needs to test both the circulatory and respiratory systems.

A glucose solution has a density of 1.02 g/ml. what is its specific gravity
Makovka662 [10]
Answer is: specific gravity of glucose is 1,02.
d(glucose) = 1,02 g/ml.
d(water) = 1,00 g/ml.
Specific gravity of glucose = density of glucose ÷ density of water.
Specific gravity of glucose = 1,02 g/ml ÷ 1,00 g/ml.
Specific gravity of glucose = 1,02.
Specific gravity<span> is the ratio of the </span>density<span> of a substance (in this case glucose) to the density of a reference substance (water).</span>

For the following reaction, 4.64 grams of oxygen gas are mixed with excess benzene (C6H6). The reaction yields 3.95 grams of car
Reil [10]

Answer:

Theoretical yield for CO₂ is 5.10g

Explanation:

Reaction: 2C₆H₆(l) + 15O₂(g) → 12CO₂(g)  + 6H₂O(g)

We convert the mass of oxygen to moles:

4.64 g /32 g/mol = 0.145 moles of O₂

Let's find out the 100% yield reaction of CO₂ (theoretical yield)

Ratio is 15:12. So let's make this rule of three:

15 moles of O₂ can produce 12 moles of CO₂

Therefore 0.145 moles of oxygen will produce (0.145 . 12) /15 = 0.116 moles

We convert the moles to mass: 0.116 mol . 44 g / 1mol = 5.10 g

How many sugar molecules are in 0.734 mol sugar, C6H12O6? Please explain
Dmitrij [34]
To answer this question, you need to know the Avogadro number. To find the amount of sugar molecule from mol unit you need to multiply it by the Avogadro number.
The calculation should be like this: <span>0.734 mol * 6.02*10^23 molecule/ mol= 4.41 * 10^23 molecule</span>

Please help!!! Stoich Question
Greeley [361]

Answer:

4KO₂ + 2CO₂ -> 2K₂CO₃ + 3O₂

<u> Step 1: Find the moles of O₂.</u>

n(O₂) = mass/ Mr.

n(O₂) = 100 / 32 = 3.125 mol

<u>Step 2: Find the ratio between KO₂ and O₂.</u>

        <u>KO₂ </u>    :      <u> O₂</u>

          4        :       3

        4/3       :       1

  (4*3125)/3  :      3.125

=4.167 mol of KO₂

Thus now we know, to produce 100 g of O₂, we need 4.167mol of KO₂

<u>Step 3: Find the mass of KO₂:</u>

<u />

mass = mol * Mr. (KO₂)

Mass = 4.167* 71.1

Mass = 296.25 g
