Answer:  A. they are proven before being published and  D. they are reviewed by experts

Explanation:  Journals are the written documents in which the scientists jots down about his proven fact or theory which has resulted through various kinds of rigorous experiments and has also been reviewed by the scientists as well.

Before publishing any kind of own work, the scientists first try to explain it which results in experimentation. After than, it would be reveiwed through his senior authoritites like senior scientists, who will remark it and will try to modify it or amend it if they would find any kind of mistake.

After the last verdicts from the scientist , it would go for the publication.

For the reaction 2A(g) â B(g), the equilibrium constant is Kp = 0.76. A reaction mixture initially contains 4.0 atm of gas (PA =
timofeeve [1]

Answer: (a) The reaction mixture will proceed toward products.

Explanation:

Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as K_p

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

2A(g)\rightleftharpoons B(g)

The expression for Q_p is written as:

Q_p=\frac{p_B}{(p_A)^2}

Q_p=\frac{(2.0)}{(2.0)^2}

Q_p=0.5

K_p=0.76

Thus as K_p>Q_p , the reaction will shift towards the right i.e. towards the product side.

A student is performing an experiment to study thermodynamics. The student mixes citric acid and sodium bicarbonate in a calorim
seraphim [82]

Explanation :

In thermodynamics, a system is region or part of space which is being studied and observed while the surrounding is the region or space around the system which interacts with the system.

Here in the experiment ,system which is observed is reaction or changes when citric acid and sodium bicarbonate are mixed together. And the mixing is carried out in the calorimeter which serves as a surrounding around the system.

The reason behind the using the calorimeter is measure the energy change occurring during the reaction.
