Answer: Option (D) is the correct answer.

Explanation:

It is known that opposite or unlike charges attract each other and like charges repel each other.

Therefore, out of the given options only Li and Br has unlike charges. As Li has one positive charge and Br has one negative charge.

Thus, only Li and Br will attract each other as they have unlike charges.

Which of these would most likely be one of the final steps when performing a strong acid-base titration? Prepare the burette. Re
DanielleElmas [232]

Answer is: Prepare to measure pH change.

For example for strong acid-base titration, sodium hydoxide and hydrochloric can be used.

Balanced chemical reaction: HCl + NaOH → NaCl + H₂O.

In this reaction pH of equivalence point will be always 7.

Equivalence point is the point which there is stoichiometrically equivalent amounts of acid and base.  

Chemist can draw pH curve (graph showing the change in pH of a solution, which is being titrated) for titration and determine equivalence point.  

Near equivalence point indicator should change color, so we must pick indicator who change color near pH of equivalence point.

Plant cells undergo a process called photosynthesis, which uses sunlight to make sugar. Which need does photosynthesis fulfill f
AlexFokin [52]

Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

The graphics below shows how photosynthesis and cellular respiration are related.
lisov135 [29]

Options found from another source are:

a. oxygen. b. glucose. c. energy stored as ATP. d. carbon dioxide and water

Answer:

c energy stored as ATP

Explanation:

Cellular respiration converts glucose into energy in the form of ATP (c). The answer cannot be oxygen (a), because this is required for this process as a final electron acceptor. In terms of photosynthesis, oxygen is released as a by-product. The answer cannot be glucose (b) because that is our starting point for respiration, and what is synthesised during photosynthesis. The answer cannot be (d) as carbon dioxide and water are released by cellular respiration, and required by photosynthesis
