If the step for digesting the precipitate were omitted what would be the probable consequence of reporting the percent limiting reactant in the salt mixture Explain?
If the step for digesting the precipitate were not followed, it could result in a different amount of limiting reactant. For example, some may get through and the calculated limiting reactant may actually be less than what is in there.
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 iron sulfate reactant or a product?
Reactant
What determines the coefficient ratio used to predict the amount of product produced from any given amount of reactant?
The reaction equation gives the RATIO of moles reactant to moles product. With known molar mass the (mass) yield can be calculated. (Of course other reactants are to be in excess! for complete reaction of the reactant involved for this yield)
A reactant in photosynthesis that is a liquid?
Water is a reactant in photosythesis that is a liquid.
Why is it necessary to identify the limiting reactant when you want to know how much product will form in a chemical reaction?
The limiting reactant tells you how much of each reactant is formed. If you use the excess material a false answer for the calculated products will come out.
What must be known for the rate constant to be calculated for the rate law?
The reaction rate at known reactant concentrations.
What must be known for the rate constant to be calculated from the rate law?
The reaction rate at known reactant concentrations.

What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
What are three characteristics of enzymes?
1. increase the rate of reaction 2. act specifically whith only one reactant to produse products 3. regulated from a state of low activity to high activity and vice versa
