Food molecules contain biochemical energy which is made available by a process called respiration.

Respiration is the process within cells by which living things break down food chemicals in their bodies and use them as a source of energy.

The proteins, lipids and polysaccharides that make up most of the food we eat must be broken down into smaller molecules before our cells can use them either as a source of energy or as building blocks for other molecules. This process is named catabolism and occurs in 3 stages.

Stage 1 is the enzymatic breakdown of food molecules in the digestion process into their monomer subunits- amino acids, glucose and glycerol.

Stage 2 is the process of glycolysis where each molecule of glucose is converted to pyruvate.

Stage 3 is production of ATP, the form of energy needed by the body to function. This stage takes place in the mitochondria of the cells. ATP is produced from conversion of pyruvate to acetylCoA in a process called the Citric Acid Cycle.

The molarity of an aqueous solution of hydrochloric acid, , is determined by titration with a M barium hydroxide, , solution. If

spin [16.1K]

Answer:

See explanation.

Explanation:

Hello there!

In this case, for this titration problem, we first need to set up the undergoing chemical equation between barium chloride and hydrochloric acid:

$2HCl+Ba(OH)_2\rightarrow BaCl_2+2H_2O$

Which occurs in a 2:1 mole ratio of acid to base and thus, we can write the following:

$2n_{base}=n_{acid}$

Which can be written in molarities and volumes:

$2M_{base}V_{base}=M_{acid}V_{acid}$

And we solve for the molarity of the acid:

$M_{acid}=\frac{2M_{base}V_{base}}{V_{acid}}$

Unfortunately, the molarity of the base was not given:

"The molarity of an aqueous solution of hydrochloric acid, , is determined by titration with a M barium hydroxide, , solution. If 31.2 mL of barium hydroxide are required to neutralize 15.4 mL of the acid, what is the molarity of the hydrochloric acid solution?"

Yet we can assume an arbitrary value, say 1.0 M in order to show you the solution so that you can modify it according to your given value:

$M_{acid}=\frac{2(1.0M)(31.2mL)}{(15.4mL)}=4.05M$

So you just need to modify the (1.0 M) by the actually given molarity of the acid.

Regards!

5. For the equilibrium

Elodia [21]

The reaction quotient of the reaction is 7.00238.

From the question.

BrCl2 is 0.004150

Br is 0.003660

Cl is 0.00067210

Q={BrCl2}/{Br}{CL2}

Q=0.004150^2/(0.0036660)(0.00067210)

Q= 7.00238

<h3>What is equilibrium?</h3>

Equilibrium of chemical reaction is the process in which the reaction remain constant and it is either moving backward or forward.

Therefore, The reaction quotient of the reaction is 7.00238

When does the number of electrons be greater than the number of protons?And give examples.

vova2212 [387]

Answer:

This accepting atom will then become an anion. The anion has more electrons than protons. This means that some of the electrons will not be canceled out, giving the atom an overall negative charge.

If an object has more protons than electrons, then the net charge on the object is positive. If there are more electrons than protons, then the net charge on the object is negative. If there are equal numbers of protons and electrons, then the object is electrically neutral.

Most nadh molecules generated during cellular respiration are produced during __________.

ahrayia [7]

Most of the NADH molecules that are made during cellular respiration are produced in the citric acid cycle. This cycle is also known as Krebs cycle. It is a set of reactions that happen in all organisms who requires oxygen in order for them use up the stored energy.
