Which ones are the reactants in a chemistry equation?
Simply, the reactants are the original substances that are present at the beginning of a reaction. For example, in this reaction: 2Na + Cl2--> 2NaCl, the reactants are the Na and Cl.
Why do reaction rates slow as time goes on?
There are fewer reactants left to collide.
What are skeletal reactions?
skeletal reaction is writing an equation without following the law of conservative.
What is the chemical reaction occurs when two(2) compounds simply switch their constituents to form new elements?
This is a double displacement reaction.
Is melting salt a chemical reaction or physical reaction?
simply yes, because if you put them together, then the chemicals collide and therefore makes a chemical change.

What reactions occurs when rubbing alcohol and water?
There is no chemical reaction between isopropanol and water, they simply mix.
How is rate of a chemical reaction usually expressed?
Rates of reaction can be expressed depending upon their order.For example say you have a reaction between two chemicals and the initial rate for that reaction is known :-when:-The concentration of one of the reactants is doubled and the other reactants concentration remains the same and the overall rate of reaction does not change - reaction is zero orderwith respect to chemical which was doubled.The concentration of one of the reactants is doubled and other reactants concentration remains the same and the overall rate of reaction doubles - reaction is first order with respect to chemical which was doubled.The concentration of one of the reactants is doubled and other reactants concentration remains the same and the overall rate of reaction quadruples - reaction is second order with respect to chemical which was doubled.Zero Orderrate = kFirst Orderrate = k [A] (reaction is 1st order with respect to [A] and 1st order overall)Second Orderrate = k [A][B] (reaction is first order with respect to [A] and first order with respect to[B], reaction is second order overall)rate = k [A]2 (reaction is second order with respect to [A] and second order overall)Orders are simply added together in order to determine the overall order of reaction :-rate = k [A][B][C] would be third order overall and first order with respect to each of the reactantsThere are other orders of reaction, for example 2 and 3 quarter orders and third order reactions, but these are a little more complex.
What does the difference in potential energy between the reactants and products represent?
It represents the change in enthalpy for the reaction.
How is the rate of reaction compared with the time the reaction is carried out?
The time it takes for a reaction to occur is a function of the reaction rate constant and the amount of reactants. However, how long it takes for a reaction of occur completely depends on the type of reaction it is -- what the order of the reaction is. A first or second order reaction reaction will occur much faster earlier on, but slows down significantly once the reactants are depleted. The rate of a zero order reaction is constants regardless of the concentration of the reactants.
Is melting salt a chemical reaction or physical reaction?
simply yes, because if you put them together, then the chemicals collide and therefore makes a chemical change.
Dr Mickster combined several nitrogen atoms together in a chemical reaction which did he create?
It is a nitrogen compound Simply because a chemical reaction happens in a compound. So, when he made a chemical reaction he made a compound.
What does conservation of mass have to do with an equation?
In a chemical reaction, which is what a chemical equation represents, the numbers of atoms of each element are the same in the reactants and the products. This is because, in a chemical reaction, the atoms in the reactants are not changed, they are simply rearranged into new compounds in the products. Therefore, matter is neither created nor destroyed. This is why it's important to balance a chemical equation properly so that the numbers of atoms of each element is equal on both sides.
What is catalist?
A catalyst is a substance that accelerates a chemical reaction. It does this by lowering the activation energy necessary for that reaction to start. A catalyst is not a reactant or a product, and it does not get used up in a reaction. It is simply present with the reactants and the products and it does not change in a reaction. In an equation, it is correct to show the chemical formula for the catalyst in small characters above the "yield" arrow. The opposite of catalyst is inhibitor.
