No.
Some indicators of a chemical reaction are:
- change of color
- change of odor
- release of a gas
- change of the temperature
- change of the viscosity
- formation of a precipitate
- change of general appearance
- possible explosion
- possible chemiluminescence -formation of new compounds
Yes - that is correct.
When a chemical reaction takes place, usually burning and fizzing are seen.
In a chemical reaction that proceeds to completion, there will be reactants and products at any time during the reaction. Reactants are the substances that react to produce products. This occurs through collisions that happen on the microscopic level. Two reactant particles cannot react unless they collide with the correct orientation and sufficient energy to form an activated complex, which is the intermediate molecule between reactants and products.
silver chloride AgNO3(aq) + KCl(aq) --> AgCl(s) + KNO3(aq)
12 J/3 moles = 4 J/mole. Thus, H of reaction in kJ/mole = 0.004 kJ/mole
The enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
The detective positioned himself in the shadows of some bushes, from where the suspect was observable.
The correct spelling is "reaction of copper with...' 1. Chemical reactivity is a chemical property. 2. A chemical reaction involve a chemical change.
That is precisely correct.
Yes, that is correct.
The difference is reactants are material used before the chemical reaction. And products are the new substances created as a result of the chemical reaction. Correct me if im wrong... but im almost positive this is correct
It is a chemical reaction and this is the correct way to spell penny!
Yes, this is a correct chemical reaction.
Yes, enzymes are not consumed in a chemical reaction. They act as catalysts, speeding up the reaction without being altered or used up in the process. This allows enzymes to be used repeatedly.
The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction, it can only change forms. This means that the total mass of the reactants must be equal to the total mass of the products in a chemical reaction.
