In any chemical reaction the quantities that are preserved are?
In any chemical reaction the quantities that are conserved are mass and number of atoms. After the correct formula for a reactant in an equation has been written, the formula should not be changed.
Is copper sulphate a reactant or a product in the following equation copper sulphate plus sodium hydroxide equals copper hydroxide plus sodium sulphate?
Copper sulfate is a reactant in the equation as stated, because it is present before the reaction has occurred and no longer present afterward.
What is a reactant in a chemical equation example?
Almost any chemical element or compound can participate in some type of chemical reaction and thereby be a reactant. One of the more common reactants is oxygen. It may be that only helium can never be a reactant.
What is a limiting agent?
In many chemical reactions, there are two reactants. In nearly every case, one of those two reactants "runs out" first, and at that point, the chemical reaction stops, because in order for it to happen, both reactants must be present to react with each other. As soon as the one reactant runs out, the reaction is over, and you have product(s) and one left over reactant. The reactant that runs out first is the limiting reactant. The leftovers are the excess reactant.
What is a excess reagent?
In most reactions there are two types of reactant. One of them is completely consumed and the other is only partially consumed. The reactant that is only partially consumed is the excess reactant.
What is the reaction between elements called?
A reacted element is called Reactant. It is present on left side of chemical equation.
What role does a reactant play in a chemical reaction?
Reactants is what the substances used in a chemical reaction are called. For example when burning hydrogen the reactants oxygen (O2) and hydrogen (H2) form the product water (H2O).
Why is a catalyst written above the arrow in a chemical equation rather than with the reactants?
The enzyme is written above the arrow of the chemical equation because it is involved in the reaction without being changed by it or used up in the reaction. It is not a reactant or a product.

What is the chemical equation for strontium phosphide and barium phosphate?
A chemical equation is a written symbolic representation of a chemical reaction. The reactant chemical(s) are given on the left-hand side and the product chemical(s) on the right-hand side. The law of conservation of mass states that no atoms can be created or destroyed in a chemical reaction, so the number of atoms that are present in the reactants has to balance the number of atoms that are present in the products phospheric acid= H3PO4 strontium oxide= SrO
What is a substance that enters into a chemical reaction called.?
The reactant is the substance present at the start of a chemical reaction, while the product is the substance(s) formed from a chemical reaction.
Why an unbalanced chemical equation cannot fully describe a reaction?
An unbalanced equation (skeleton equation) only indicates the nature of the reactants and products but tells nothing of the stoichiometric ratios, i.e. it tells nothing of how much of each species is present, not which reactant might be in excess or limiting, etc.
What are the substances that are present before a chemical reaction starts?
The reactants exist before a reaction begins, and also the products are the result of the reaction of the reactants.
Which is chemical equation?
A chemical Equation is a shorthand form of a chemical reaction. chemists use it to help them tell the substances that are present such as reactants, products, or proportions.Some equations also tell the physical state of a substance.

In nearly every case, one of those two reactants "runs out" first, and at that point, the chemical reaction stops, because in order for it to happen, both reactants must be present to react with each other.
