Functions of the following equipment's are-
1. ASPIRATOR is a suction machine .It is a medical device that is primarily used for removing obstructions such as mucus, saliva, blood, or secretions — from a person's airway.
2.Beakes are useful as a reaction container for holding liquid or solid samples. They are also used for catching liquids from titrations and filtrates from filtering operations.
3. pipettes are used in laboratory to measure out or transfer small quantities of liquid, in volumes of milliliters (mL), microliters (μL).
4. fire tongs are used for holding hot apparatus.
5. test tubes are used for holding solutions and carrying out the reactions.

The largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution.
<h3>What is a precipitation reaction?</h3>
A precipitation reaction is a reaction in which an insoluble substance is obtained when two solutions are mixed together as a result of one of the products of the reaction being insoluble in water.
Silver chloride is an insoluble salt that will precipitate when a single silver salt is added to a soluble chloride salt.
In the above, the largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution since iron (iii) chloride is a weak electrolyte.

Answer:
Most of free energy available from oxidation of the glucose remains in pyruvate.
Explanation:
The overall reaction of the process glycolysis is:
Glucose + 2 NAD⁺ + 2 ADP + 2 Pi ⇒ 2 Pyruvate + 2 NADH + 2 H⁺ + 2ATP
Glucose is oxidized to give 2 molecules of pyruvate and 2 molecules of NADH and ATP (Energy currency).
<u>Though the free energy of oxidation of glucose is high but only 2 NADH is formed because the most of the free energy that is being released from the oxidation of glucose remains in the pyruvate which is produced in the reaction and thus only 2 molecules are formed.</u>
Answer:
Explanation:
The substances that are present at the beginning are called reactants and the substances present at the end are called products. Sometimes when reactants are put into a reaction vessel, a reaction will take place to produce products. Reactants are the starting materials, that is, whatever we have as our initial ingredients.Oxygen, a colorless, odorless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere. Oxygen forms compounds by reaction with practically any other element.

The displacement is -4 S
21 - 25 = -4
