What is/are converted into carbon dioxide , water, and energy in aerobic respiration
Lana71 [14]

Cellular respiration involves breakdown of glucose into carbon dioxide and water in presence of oxygen, releasing energy. ... ATP molecule is converted into ADP molecule, whenever energy is needed for any metabolic reaction or activity. The energy stored in it is released to be used in metabolic reaction.

Hope this helps! So sorry if I'm wrong

5. Citric acid is the main acid present in lemon juice. However vitamin C, or ascorbic acid is
aev [14]

In the titration of lemon juice, the presence of ascorbic acid means the concentration of citric acid you calculated is higher.

An acid-base titration is a common way to determine the unknown concentration of an acid, given we know the concentration of the base and determine the spent volume in the titration. Let's consider the neutralization reactions that take place in a mixture of citric acid and ascorbic acid.

Citric acid titration :

3 NaOH(aq)  +  H₃C₆H₅O₇(aq)  →  Na₃C₆H₅O₇(aq)  +  3 H₂O(l)

Ascorbic acid titration:

NaOH(aq) + HC₆H₇O₆(aq)  →   NaC₆H₇O₆(aq)   +  H₂O(l)

If we titrated a solution that contained only citric acid, we can relate through stoichiometry the moles and concentration of citric acid. However, if the solution also contained ascorbic acid, we would have to spend more NaOH to titrate it. Since more NaOH would react, we would conclude that there is more citric acid to react, calculating a higher concentration of the same.

In the titration of lemon juice, the presence of ascorbic acid means the concentration of citric acid you calculated is higher.

How does a nuclear reactor produce electricity?
inessss [21]

B. The heat from the reaction turns water to steam, which runs a generator.

<h3>Explanation</h3>

Here's what's going on within a <em>typical</em> nuclear power plant.

  • The fuel bundle undergoes fission to release heat.
  • A coolant such as molten salt flows across the reactor and transfers heat away from the fuel.
  • The coolant is then passed into a heat exchanger. Cold water goes through the heat exchanger to absorb the heat. The coolant cools down and is recycled.  Water heats up and boils to produce steam.

The rest of this process resembles that of a coal power plant.

  • Steam from the heat exchanger goes through a turbine, which drives a generator.
  • Some water condenses and is recycled.
