What describes the energy of activation?
Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
If 5 grams of substance A reacts with 10 grams of Substance B how many grams of product are formed?
It depends on the chemical reaction between substance A and substance B. The stoichiometry of the reaction will determine the amount of product formed. You would need to balance the chemical equation to calculate the exact amount of product formed.
How does activation energy determine if a reaction will release or absorb energy?
Activation energy is the energy required to start a chemical reaction. If the activation energy is higher than the energy released by the reaction, the reaction will absorb energy and be endothermic. If the activation energy is lower than the energy released by the reaction, the reaction will release energy and be exothermic.
What is the maximum amount of that can theoretically be made from 186 of and excess oxygen?
To determine the maximum amount of a product that can theoretically be made from 186 grams of a substance and excess oxygen, we need to know the specific chemical reaction and the molar mass of the substance involved. Without this information, we cannot calculate the theoretical yield. Please provide the chemical formula or reaction details for a more accurate answer.
What determines the amount of chemical energy a substance has?
The amount of chemical energy a substance has is determined by the types and arrangement of atoms and molecules in that substance. The energy is stored within the chemical bonds between these atoms and molecules. The strength of these bonds and the potential energy stored in them determine the amount of chemical energy.
How do you calculate the percent dissociation of a substance in a chemical reaction?
To calculate the percent dissociation of a substance in a chemical reaction, you divide the amount of dissociated substance by the initial amount of the substance and multiply by 100. This gives you the percentage of the substance that has dissociated in the reaction.
What is the concept of equivalence in chemistry and how is it used to determine the amount of a substance in a chemical reaction?
In chemistry, equivalence refers to the equal amount of reacting substances involved in a chemical reaction. It is used to determine the amount of a substance by comparing the number of equivalents of different substances involved in the reaction. This helps in calculating the stoichiometry and quantities of reactants and products in a chemical reaction.
What evidence in chemical reaction in mole?
Mole is the the unit for amount of substance in SI.
What is the measured amount of a productobtained from the chemical reaction?
This is usually referred to as the ACTUAL YIELD of that substance.
What term describes a substance that lowers the amount of energy needed to start a chemical reactions?
Catalyst

What are the dimensions of amount of substance and how are they used in chemical calculations?
The dimensions of amount of substance are measured in moles. Moles are used in chemical calculations to determine the quantity of a substance in a reaction, to convert between mass and number of particles, and to calculate the molar mass of a compound.
Does chemical potential changes as reaction proceeds?
yes,as gibbs free energy depends on temp. ,its value for a fixed amount of a substance change,so chemical potential changes with reaction.
Substance with a definite shape and volume?
Items like H2O and CoC2 have a definite chemical composition, and require exact amount of particles to forma reaction. However; particles which are soluble in water do not have a definite chemical reaction.
How is heat of solution related to heat of reaction?
The heat of solution refers to the heat energy absorbed or released when a substance dissolves in a solvent, while the heat of reaction refers to the heat energy absorbed or released during a chemical reaction. The heat of solution can be a part of the overall heat of reaction if dissolution of a substance is involved in the chemical reaction.
