What is the name of the high energy compound that cells use directly to fuel other chemical reactions?

irga5000 [103]

Answer:-

ATP Adenosine Triphosphate

Explanation:-

ATP is the name of the high energy compound that cells use directly to fuel other chemical reactions. It is found in all cells. In the mitochondria, every "turn" of the citric acid cycle produces one equivalent of ATP.

ATP + H 2O → ADP + Pi+ energy

ADP is adenosine monophosphate.

In a lead-acid battery, the electrodes are consumed. In this battery, Select one: a. the anode is PbO2. b. the cathode is Pb. c.

Gnoma [55]

Answer:

The correct answer is option e.

Explanation:

The lead acid battery consists lead as an anode and lead oxide as a cathode. Both the electrodes are suspended in dilute sulfuric acid which act as an electrolyte.

At anode: Oxidation

$Pb(s)+SO_4^{2-}(aq)\rightarrow PbSO_4(s)+2e^-$

At cathode: Reduction

$PbO_2+SO_4^{2-}(aq)+4H^+(aq)+2e^-\rightarrow PbSO_4(s)+2H_2O$

Viefleur [7K]

Twice as much more will the freezing point of water be lowered in beaker a than in beaker b.

<h3>What determines freezing point?</h3>

A liquid's freezing point rises if the intermolecular interactions between its molecules are strong. The freezing point, however, drops if the molecules of inter - molecular are minimal. The process through which a substance transforms from a liquid into a solid is known as freezing.

<h3>How significant is freezing point?</h3>

Freezing points play a big role in occupational safety. A chemical may perhaps turn harmful if held below its freezing point. A critical safety benchmark for assessing the effects of worker exposure to cold environments is the freezing point.

You wish to add 5 mg/l naocl as cl2 to a solution in a disinfection test, and you have a stock solution (household bleach) that

Alecsey [184]

Answer: -

0.1 ml of bleach should be added to each liter of test solution.

Explanation:-

Let the volume of bleach to be added is B ml.

Density of stock solution = 1.0 g/ml

Mass of stock solution = Volume of stock x density of stock

= B ml x 1.0 g/ml

= B g

Amount of NaOCl in this stock solution = 5% of B g

= $\frac{5}{100}$ x B g

= 0.05 B g

Now each test solution must be added 5 mg/l NaOCl.

Thus each liter of test solution must have 5 mg.

Thus 0.05 B g = 5 mg

= 0.005 g

B = $\frac{0.005}{0.05}$

= 0.1

Thus 0.1 ml of bleach should be added to each liter of test solution.
