Answer:
Describe what is happening within the system when it is at equilibrium in terms of concentrations, reactions that occur, and reaction rates.
Explanation:
The chemical equilibrium state is the state where the rate of forward reaction becomes equal to the rate of backward reaction.
At this stage the change in concentration of reactants becomes equal to the change in concentration of products.
The reaction will never cease.
That is the reason chemical equilibrium is called dynamic equilibrium.
So, forward and backward reactions will be taking place continuously at equal rates.
Answer:
All of alpha-ketoglutarate formed in the citric acid cycle would contain the radioactive 
while none of succinate would contain , and all of carbon dioxide released would contain .
Explanation:
When oxaloacetate in the citric acid cycle is labeled with in carboxyl carbon atom which is farthest from keto group, alpha ketoglutarate formed from this oxaloactetate has the full radioactive label. In the next step, the carboxylic group (that contains the ) is eliminated in the form of the release of the carbon dioxide and succinate is formed. Succinate thus will not have radioactivity. 
released had all the radioactivity.
The first one im pretty sure
Answer:
search the Lewis dot structure you will know the answer.
Explanation:
The substance A and B will mix into one solution as it is a solvent interactions which is greater than or equal to the solute- solute and the solvent-solvent interactions. Thus when such interactions occurs, it is greater or equal to the some of the other two possible interactions. And here both have the same kind of interaction, and same magnitude, so they will makes to form a solution and mixes properly and spontaneously.
