When talking about enzymes where do reactant molecules bind and convert chemically product?
In enzymes, reactant molecules bind to a specific region called the active site. This is where the chemical reaction takes place and the reactants are converted into products. The active site has a specific shape that matches the reactants, allowing for precise binding and conversion.
How do you calculate theoretical yield?
When calculating the theoretical yield of a product within a reaction, the idea is to convert mass reactant --> mass product; in other words, "how many grams of product X will N grams reactant A and N grams reactant B yield (create)?" Whichever mass is the lowest is considered the theoretical yield (in other words, the reactant that produces the least amount of product).__A + __B --> __Xmass reactant A => mass product X (mass A: mass X)mass reactant B => mass product X (mass B: mass X)In order to calculate the theoretical yield, you need to convert the mass of reactant A to the mass of product X AND the mass of reactant B to the mass of product X.1. Multiply the mass of the reactant by the number of molecules (or moles) X and by the molar mass of X.2. Divide the above by the molar mass of reactant (which is multiplied by the number of molecules [or moles] of reactant).Do this for each reactant involved.- FormulaMass reactant * # molecules (moles) product X1 * molar mass product X--------- # molecules (moles) reactant * molar mass reactant= Mass Product X- Conversion FactorMass reactant * 1 mol reactant * # molecules product X * molar mass product X-------------- molar mass reactant - # molecules reactant --- 1 mol product X= Mass Product X1the # molecules is obtained from the balanced equation. For clarification, I stated # molecules in place of mol; however, on practice problems and in textbook tutorials on how to solve problems in regards to stoichiometry, it is likely it will say mol or moles instead of # molecules.Ex. Ca(NO3)2 + 2NaF --> CaF2 + 2NaNO3What is the theoretical yield of CaF2 (product X) when 43.5g Ca(NO3)2 (reactant A) react with 39.5g NaF (reactant B)?43.5g Ca(NO3)2 * 1 mol Ca(NO3)2 * 1 molecule1 CaF2 * 78.08g CaF2-------------- 164.1g Ca(NO3)2 ----- 1 molecule1 Ca(NO3)2 - 1 mol NaF= 22.3g CaF236.5g NaF * 1 mol NaF * 1 molecule1 CaF2 * 78.08g CaF2------------ 41.99g NaF --- 2 molecules1 NaF --- 1 mol CaF2= 36.7g CaF2The theoretical yield of CaF2 is 22.3g, as it is the lowest amount of product created. In this case, the limiting reagent (the reactant that produced the least product) is Ca(NO3)2 and the reagent in excess is NaF."A chain is only as strong as its weakest link".
When two reactant molecules or atoms interact the product will have?
No new properties
What are the steps in a stoichiometry problem that starts with grams of a reactant?
Convert grams of the given reactant to moles using its molar mass. Use the mole ratio from the balanced chemical equation to convert moles of the given reactant to moles of the desired product. Convert moles of the desired product to grams using its molar mass, if needed.

Why does surface of a reactant influence the rate of the reaction?
A chemical reaction is nothing but the conversion of the reactant molecules into product molecules. By increasing the surface area of the reactants more number of reactant molecules are exposed which eventually increases the rate of the reaction...for example, powdered chalk piece dissolves faster in water than a piece of chalk.

Is sulphur a reactant or a product?
reactant
Why are catalysts spread out in a reaction?
Catalysts are chemicals that alter the rate of a chemical reaction without being chemically changed themselves . However to alter the rate of the reaction , the catalysts need to come in contact with the reactant particles. Spreading out the catalyst increases its surface area , hence increases the chances of coming in contact with the reactant particles . So they are able to provide the reactant particles an alternative route with a lower activation energy for the reactant particles to collide and form the product .
Is cobalt a reactant product or reactant and product?
This depends on the reaction involved.
