What else can I help you with?
A chemical reaction occurs between sodium hydroxide and hydrogen chloride Adding more sodium hydroxide to the reaction causes it to speed up If you add more of a reactant such as sodium hydroxide?
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
What information in a balanced chemical equation shows how many moles of a reactant are involved in the reaction?
The coefficient (not a subscript or superscript) placed immediately before the formula of the reactant in the equation shows how many moles of a reactant are involved in the reaction. If there is no explicit coefficient, a value of 1 for the coefficient is assumed. The coefficient in front of the molecule tells its relative number of moles.
What does the difference in potential energy between the reactants and products represent?
It represents the change in enthalpy for the reaction.
If one knows the mass and molar mass of reactant A and the molar mass of product D in a chemical reaction one can determine the mass of product D produced by using the?
Balanced chemical equation along with the stoichiometric ratios derived from that chemical reaction. A + B --> 2C mass of A * 1/molar mass of A = moles of A Moles of A * 2 moles of C/mole of A = moles of C Moles of C * molar mass of C = mass of C Also, you must think about limiting reagents, because if there is not enought reactant B to react with the amount of reactant A then the amount of reactant B will limit the production of product C!
What is the diffrencence between exothermic reaction and chemical reaction?
A chemical reaction is a process that involves the breaking and forming of chemical bonds to create new substances. An exothermic reaction is a type of chemical reaction that releases heat energy to the surroundings. In other words, all exothermic reactions are chemical reactions, but not all chemical reactions are exothermic.
What is the difference between a reaction and products of a chemical reaction?
reactant + reactant = product
Difference between a reactant and product?
A reactant is a substance that undergoes a chemical reaction, while a product is a substance that is formed as a result of that reaction. Reactants are consumed during the reaction, while products are the end result of the reaction.
What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?
Decreasing the concentration of a reactant will typically decrease the rate of a chemical reaction, as there are fewer reactant molecules available to collide and form products. This is in line with the rate law, which often shows a direct relationship between reactant concentration and reaction rate.

What is the equation that has water as a reactant in chemical reaction?
An example of a chemical equation with water as a reactant is the reaction between hydrogen gas and oxygen gas to form water: 2H2 + O2 -> 2H2O.
What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
What term refers to the difference between the energy of the transition state and the energy of the reactants?
The term that refers to the difference between the energy of the transition state and the energy of the reactants is activation energy. It represents the energy threshold that must be overcome for a chemical reaction to occur.
What information in a balanced chemical equation shows how many moles of a reactant are involed in the reaction?
The coefficients in a balanced chemical equation indicate the mole ratio between reactants and products. This allows us to determine the number of moles of each substance that participate in the reaction based on the stoichiometry of the reaction.
What is the difference between an effective collision and ineffective collision of reactant particles?
An effective collision between reactant particles results in a chemical reaction, while an ineffective collision does not lead to a reaction because the particles do not have enough energy or correct orientation to break and form bonds. In an effective collision, reactant molecules collide with sufficient energy and in the correct orientation to overcome the activation energy barrier and form product molecules.
What is the term for a substance undergoing a chemical change?
The other term for a chemical change is a chemical reaction. They both refer to a reaction between different components chemically to make a product that is different from them in terms of chemical structure.
What is the difference between rate of reaction and chemical equation?
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
What is the difference between a reactant and a catalyst?
A reactant is consumed in a reaction to make products. A catalyst is not consumed during the reaction. It is either not directly involved in the reaction or regenerated upon the end of the reaction. This is the main difference. In addition, catalysts work by decreasing the activation energy for the reaction, allowing the reactants to react more easily.
