What is stoichimetry used for?
stoicheiometry is the division of chemistry that mainly deals with the relationships in combining elements.
What happens to ammonia when I increase the amount of reactants?
When you increase the amount of reactants in a reaction involving ammonia, the equilibrium position may shift according to Le Chatelier's principle. If the reaction is reversible, adding more reactants can drive the reaction toward the products, potentially increasing the concentration of ammonia produced. However, the specific outcome also depends on the reaction conditions and the nature of the reaction itself. Overall, increasing reactants generally promotes the formation of more ammonia until a new equilibrium is reached.
Where does the theoretical yield come from the amount of product you get in a reaction or the amount of product that could be made from the limiting reagent?
The amount of product you get in a reaction
What is theoretical yield of a reaction?
The amount of product that is possible in a reaction.
Does the catalyst change the amount of energy released in the reaction?
no. the amount of catalyst does not influence the reaction; A catalyst simply provides an alternative route for the reaction with a lower activation energy.
Are substrate and catalyse the same thing?
No! A substrate is a reagent in a chemical reaction. Catalyse is the verb form of catalyst; a catalyst is a chemical species that participates in lowering the energy barrier of a chemical reaction and allow a reaction to occur more rapidly. A catalyst is not consumed in a reaction and therefore only a small amount of catalyst is required in any reaction (if required at all), whereas a substrate must be present in the proper stoichiometric amount to allow a reaction to proceed as it is consumed.
How do you determine amount of enzyme consumed in a reaction?
There is no catalyst that is consumed in reaction which it is catalysing. In other reactions, eg. breakdown reactions, they do not catalyse their own breakdown! Enzymes are (bio)catalysts mainly as special protein molecules. In the reactions that ARE catalized they are not consumed, otherwise they were not 'catalists' but 'reactants'.
What are the key findings from the stoichiometry lab involving the reaction of iron with copper sulfate, and how do these results contribute to our understanding of the relationship between the two substances?
The key findings from the stoichiometry lab involving the reaction of iron with copper sulfate show that the reaction follows the law of conservation of mass. This means that the amount of iron reacted with copper sulfate is directly proportional to the amount of copper produced. These results contribute to our understanding of the relationship between iron and copper sulfate by demonstrating the stoichiometric ratio between the two substances in the reaction.
Why is permanganate estimation completed in acid?
it provides the H+ ions to catalyse the reaction
What happens to the temperature when the mass is increased in a chemical reaction involving magnesium and hydrochloric acid?
Increasing the mass of magnesium in a reaction with hydrochloric acid will not directly affect the temperature of the reaction. The temperature will be determined by the amount of heat released or absorbed during the reaction, which depends on the specific reaction and the initial conditions.

When you slove a problem involving money what can a negative answer represent?
When solving a problem involving money, a negative answer can represent an overdrawn account or an amount owed.
How does the amount of enzymes ect the reaction rate?
the more enzymes, the faster the reaction
What does enthalpy of reaction measure?
The amount of energy that is used or released as heat in a reaction.
