How can one tell if a reaction has reached its equilibrium?
All motion ceases
What is heat During the endothermic reaction?
The heat spreads to the colder substance until the two are at an equillibrium (the two objects at the end will have the same temperature)
How can your tell hat is oxidize in a redox reaction?
my reactant is Cl2 plus 2NaBr, my product is 2NaBr2. Which one is oxidized, what is reduced. How can I tell which one is which?
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
When giving the rate of a chemical reaction why would it be significant to know that the reaction rate is an average reaction rate?
Reaction rates are dependent on the concentration of reactants. As a reaction proceeds, the reactants are used up and thus their concentration is lowered. THis means that the maximum rate of reaction will be at or immediately after time zero, when the reaction is only just begun, and the minimum will be when one or more of the reactants' concentrations have reached zero. Thus, any rate stated for the reaction would only hold for a specific time in the reaction progress and cannot be extrapolated to cover all of that progress. So a mean rate of reaction must be used; this can tell a person, when combined with either the time of beginning, time of ending, or the initial concentrations, what any of the others were for the reaction in question. This is impossible to do if given a specific rate and the time it applied to; you cannot calculate any new information from just those two data.

How can one Tell how much of a reactant will be used in a reaction?
The ratio of the coefficients tells the ratio of moles of reactants used in the reaction.

What is Charles reaction to the story that mama tells about the horse?
When Charles hears his mama tell the story about the horse, his reaction is a very emotional one. However, he hides it from his mother.

What does the equilibrium constant tell you?
The equilibrium constant can tell us how the reaction is going. If the constant is grater than one there are more products than reactants, so the reaction os closer to completion. If the equilibrium constant is less than 1 it shows that there are a lot more products than reactants so the reaction has not really started yet.
If an enzyme is added to a solution where its substrates and products are in equillibrium what would occur?
If the enzyme is reversable (can catalyse the reaction in both directions such as Carbonic Anhydrase - H20 + CO2 <-> HCO3 + HO) And assuming that the conditions are such that no one direction is favoured over the other, Then the enzyme will randomly catalyze the products into substrates and vice versa with the net result being equilibrium is maintained. If on the other hand the enzyme will only work in one direction (S -> P) then, depending on the kinetics of the reaction, Substrate would be converted into product disrupting the equilibrium.
How does an equilibrium reaction respond to the addiof extra reactant?
The concentration or activity of the product(s) will increase, and if there is at least one other reactant than the added one that is required for the completion of the reaction, the concentration of such an unadded reactant will decrease. (If there were no available unadded reactant, the reaction would not technically have been in equilibrium at the start, even though it may have reached a steady state that can persist for a long time in the absence of changed conditions.)
Is 'can be reached on his cell phone' correct or 'can be reached at his cell phone'?
Either one is acceptable.
