What else can I help you with?
What must be produced in a chemical reaction to result in a chemical esplosion?
Usually a reaction must produce some sort of gas to be explosive.
What must a occur for a change to be a chemical reaction?
The answer choices weren't provided. There must be a change in chemical properties for a change to be considered a chemical reaction.
Is a new substances must form is true about chemical reaction?
Yes, after a chemical reaction new substances are formed.
Can a chemical reaction occur without any new substanced?
No, in order for a chemical reaction to take place, a new chemical substance must be formed.
What type of chemical reaction occurs when energy must be provided for the reaction to take place?
This is an endothermic reaction.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
What must combined to create a chemical equation?
Reactants and products must be combined to create a chemical equation. Reactants are the starting materials that undergo a chemical reaction, while products are the substances that are formed as a result of the reaction.
What must be absorb before a chemical reaction can start by the reactants?
energy
What must be added to a reactant to start a chemical reaction?
Either an energy source to start the reaction or a catalyst.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
What is the scientific word for a gas given off during a chemical reaction?
A reaction that emmits heat is called an exothermic reaction .
Which factors must be equal in a reversible chemical reaction at equilibrium?
At equilibrium in a reversible chemical reaction, the rates of the forward and reverse reactions must be equal. This means that the concentrations of the reactants and products remain constant over time.
