Answer: Option (B) is the correct answer.

Explanation:

Molar mass is defined as the sum of atomic mass of all the atoms present in a compound.

For example, atomic mass of barium (Ba) is 137.32 g/mol and atomic mass of a bromine atom is 79.90 g/mol.

Therefore, calculate molar mass of BaBr_{2} as follows.

                   Molar mass = atomic mass of Ba + 2 \times atomic mass of Br

                                       = 137.32 g/mol + 2 \times 79.90 g/mol

                                       =  297.12 g/mol

Therefore, we can conclude that molar mass of BaBr_{2} is 297.1 g/mol.

EFFECTS Of The<br> HUMAN INTERVATION OF THE<br> CARBON CYCLE.
vladimir2022 [97]

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

Two scientists, Tara and Victor, work in the same scientific field of study. Victor asks Tara to review a research paper that he
sashaice [31]

Answer:

Tara does not get the same results when she conducts the experiment

Explanation:

<em>The most likely reason Tara suggested to Victor to perform the experiment again before publication would be because she did not get the same results when she conducted the experiment.</em>

A good scientific research or experiment should have an element of reproducibility. In order words, the claim made in published scientific research should be reproducible by any other scientist that decides to replicate the research. <u>Tara repeated Victor's experiment in order to check its reproducibility and when she could not reproduce the results, she had to tell Victor to conduct the experiment again before deciding to publish it.</u>

What must be true about two objects if heat is flowing between them?
Degger [83]

The objects may exchange heat between each other if they are in contact with each other.

The two objects will allow flow of heat between them if they have a difference in temperature from each other.

The heat will flow from higher temperature object to lower temperature object. The will reach a final temperature (common to each other) and then there will be no heat transfer between each other.
