<span>An acid-base indicator (e.g., phenolphthalein) changes color depending on the pH. Redox indicators are also frequently used. A drop of indicator solution is added to the titration at the start; when the color changes the endpoint has been reached, this is an approximation of the equivalence point.</span>
22.4 L<span>So, if 1 mole occupies 22.4 L, the imediate conclusion is that a bigger number of moles will occupy more than 22.4 L, and a smaller number of moles will occupy less than 22.4 L. In your case, 3 moles of gas will occupy 3 times more volume than 1 mole of gas.</span>
B is the answer. For an equation to be balanced there must be the same amount of each element on the two sides. The only one where this is the case is B.
Answer:

The key enzyme in the regulation of the citric acid cycle is citrate synthase. It functions in the mitochondria.
<h3>Citrate synthase and cellular respiration </h3>
Cellular respiration is a series of reactions that produce ATP by using the energy stores in the chemical bonds of foods.
Cellular respiration is divided into glycolysis, the citric-acid cycle and oxidative phosphorylation.
Citrate synthase is an enzyme found in the mitochondrial matrix, which is involved in the citric acid cycle.
