Explain the process of cellular respiration and how and why is the energy stores

Chemistry
1 answer:
zheka24 [161]4 years ago
5 0

Cellular respiration is a process of oxidizing food molecules like glucose into carbon dioxide and water. It takes place in the cells of organisms to convert biochemical energy from nutrients into ATP molecules along with the release of waste products. It involves 4 steps namely  

  • glycolysis  
  • pyruvate oxidation  
  • the citric acid or Krebs cycle  
  • oxidative phosphorylation  

<u>Explanation:  </u>

  • The energy is stored in ATP(Adenosine Triphosphate) molecule in between the Phosphate groups.  
  • The energy released by the process is used by the cells within the organism for the growth and repair of cells and other energy-consuming activities.

How much charged is required to reduced 2 moles of cr6+ to cr3+
BartSMP [9]

Answer:

6e⁻

Explanation:

Charge in reducing 2 mole of Cr⁶⁺ to Cr³⁺

              Cr⁶⁺   +      xe⁻           →       Cr³⁺

The numbers 6+ and 3+ on the chromium atoms are the oxidation number of the atom.

It shows the number of electrons that has been lost by chromium in an oxidation state.

         Cr⁶⁺ shows that it has lost 6 electrons. When an atom loses electrons, the number of protons becomes more. This makes it positively charged in nature.

      This analogy goes for Cr³⁺

 Therefore, in going from reactants to products, chromium

                                6+      →    3+

 In this kind of expression, the number of atoms must be conserved and the charges too;

                        2Cr⁶⁺   +      xe⁻           →       2Cr³⁺

    given 2 moles of Cr;

               To balance the charge;

               2(6+) + x(-) = 2(3+)

                   12 - x = 6

                          x  = 6

A charge of 6e⁻ is required to reduce 2 mole of Cr⁶⁺ to Cr³⁺

The combustion of Ibuprofen C13H18O2 produces water and carbon
prohojiy [21]

Answer:

277.7 g of CO2

Explanation:

Equation of reaction

C13H18O2 + 11O2 ---> 13CO2 + 9H2O

From the equation of reaction

1 mole of ibuprofen produces 13 moles of CO2

Molar mass of ibuprofen is 206g

Molar mass of CO2 is 44g

13 moles of CO2 weighs 572g

Therefore, 100g of ibuprofen will produce (100×572)/206 of CO2

= 277.7g

The density of ethanol, C2H5OH, is 0.789 g/mL. How many milliliters of ethanol are needed to produce 15.0 g of CO2 via a combust
bearhunter [10]

<u>The answer is </u><u>9.94 ml.</u>

<h3>What is density?</h3>
  • Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass).
  • Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density.

Given,

        The density of ethanol, C2H5OH = 0.789 g/mL

n (CO_{2} ) = \frac{m}{M}  = \frac{15G}{44 g/mol} } = 0.341 mol;

n ( C_{2} H_{2} OH) = \frac{n (CO_{2}) }{2}  = \frac{0.341}{2}  = 0.1705  mol;

m (C_{2} H_{2} OH) = 0.1705 mol * 46  g/ mol = 7.843 g

V (C_{2} H_{2} OH ) = \frac{7.843}{0.789} = 9.94 ml.

Therefore, the answer is 9.94 ml
