When looking at a chemical reaction how do you know what the reactants and products are?
In an equation the reactants are the on the left of the arrow, and the products are on the right. For example if you had the following equation: 2H2 + O2 => 2H2O 2H and O will be the reactants and H2O is the product.
What is the starting material in a chemical reaction?
Check your local newspaper, online ads, and local signage for places to lease. As for what is the best kind of space for a small business, that would depend on what type of small business you're planning on opening.
Looking at a free energy diagram for an equilibrium reaction which of the following scenarios will favor the formation of more reactant?
The concentration of reactants is less than the concentration of reactants at equilibrium. The concentration of products is greater than the concentration of products at equilibrium.
Is Briggs Rauscher reaction and Belousov-Z reaction same?
No, but they are the two best demonstrations of oscillating reactions. The B-Z was discovered first, in the USSR in 1950. It used bromine compounds. The B-R was found in 1972 in San Francisco by two teachers looking for an iodine analogue of the B-Z. See the Wikipedia articles for more info. Warren Rauscher
What are the products made when calcium reacts with water?
There are actually two products made.When Calcium reacts with water, Calcium Hydroxide is produced and so is Hydrogen. So, both Calcium Hydroxide and Hydrogen are produced, looking like this in a word equation:Calcium + Water = Calcium Hydroxide + Hydrogen
How do you read a chemical reaction?
A chemical reaction can be read by looking at the reactants on the left side of the equation and the products on the right side. The arrow in between indicates the direction of the reaction, showing that reactants are converted into products. The chemical formulas and coefficients give information on the substances involved and the stoichiometry of the reaction.

What are the substances that are present after the reaction has taken place?
The substances present after a chemical reaction are called products. These are formed from the rearrangement of atoms from the original reactants. The products can be solid, liquid, or gas depending on the nature of the reaction.
What is the name given to a substances used in a chemical reaction?
It depends what you are talking about, reagents are the substances that you put in at the beginning of a reaction to form products. But you can also have reactions taking place within a solvent, for example H20, DMF or THF. Reagents is probably the answer your looking for though.
In a chemical reaction the number of atoms of reactants and products must?
I know that this probably isn't the answer that you were looking for but its a start the answer to this question is one of four different answers choose the one that you think is right. A) The same as the number of atoms in the reactants B) Less than the number of atoms in the reactants C) Greater than the number of atoms in the reactants D) The same as the number of molecules in the reactants
In chemistry what is the opposite of an end product?
The opposite of an end product in chemistry is typically referred to as a reactant. Reactants are the starting materials in a chemical reaction that are transformed into products. They are consumed during the reaction to form the final products.
How do you tell endothermic reaction from an exothermic reaction by looking at the chemical equation?
You have to add up the bond energies of all the bonds on the products side and the reactants side. When bonds are formed energy is released. Conversely energy has to be put into a system to break bonds (like smashing a block of ice with a baseball bat) If there is more bond energy on the products side bonds were created (energy was released) which means the reaction is exothermic. If there is more bond energy on the reactants side, bonds were broken (energy put in) and so the reaction is endothermic.

What does reactant mean in a chemical equation?
A reactant in a chemical equation is a substance that is consumed or changed in the chemical reaction. It is found on the left side of the equation and participates in the reaction to produce products.
What is the name of the product formed?
The product formed in a chemical reaction will depend on the reactants involved. The name of the product can be determined by looking at the reactants and the type of reaction that takes place between them. Naming the product typically involves identifying the elements or compounds present and using chemical nomenclature rules.
How do you determine if a chemical reaction is a redox reaction?
A redox reaction can be determined by looking at whether there is a transfer of electrons between the reactants. If one substance loses electrons (oxidation) and another gains electrons (reduction), then it is a redox reaction.
How can one predict if a precipitate will form in a chemical reaction?
One can predict if a precipitate will form in a chemical reaction by looking at the solubility of the reactants. If the product of the reaction is insoluble in the solvent, a precipitate will likely form. This can be determined by consulting a solubility table or conducting a solubility test.
