Is it correct to say that only one observable change accompanies a chemical reaction?
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
What else can I help you with?
Lithium nitride has the chemical formula Li3N.?
Yes - that is correct.
When matter changes states a physical change occurs what is needed to make this change happen?
When a chemical reaction takes place, usually burning and fizzing are seen.
What are reactants in science?
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.
What is the correct name for the precipitate formed when mixing potassium carbonate and nickel(II) chloride?
silver chloride AgNO3(aq) + KCl(aq) --> AgCl(s) + KNO3(aq)
If 3 moles of a compound use 12 J of energy in a reaction what is the H reaction in kJmol?
12 J/3 moles = 4 J/mole. Thus, H of reaction in kJ/mole = 0.004 kJ/mole
The reaction H2 Cl2 2HCl is correct?
Yes, this chemical reaction is correct. It shows the combination of hydrogen gas (H2) and chlorine gas (Cl2) to form hydrogen chloride gas (HCl) through a chemical reaction.
What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is a correct description of enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
Does this phrase was observable use correct grammar?
The detective positioned himself in the shadows of some bushes, from where the suspect was observable.
Is the reactivity of copper with oxygen considered a chemical or physical property?
The correct spelling is "reaction of copper with...' 1. Chemical reactivity is a chemical property. 2. A chemical reaction involve a chemical change.
Do emzymes increase the rate of chemical reaction they affect?
That is precisely correct.
What is the difference between reatants and productsin a chemical reation?
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
What is the correct balanced chemical equation for this reaction?
To provide the balanced chemical equation, I would need to know the specific reaction you are referring to. Can you please provide the reactants and products involved in the reaction?
What type of chemical reaction is need to absorb energy to proceed?
Endothermic Reaction.... (Just to help you out someone helped me with this question and I GOT IT CORRECT!)
What is neutalism?
The correct spelling is neutralization. It is a chemical reaction where an acid and base react to form a salt. Water is often produced in the reaction, but not always.
What information in a balanced chemical equation and shows how many moles of a reactant are involved in the reaction?
These data are given by the correct coefficients in the chemical equation.
What is correct chemical equation describing the reaction between aluminum metal and sulfur?
The chemical equation is:2 Al + 3 S = Al2S3
