Does a chemical reaction always require energy to start?
Yes, every chemical reaction requires activation energy, though in some cases the ambient heat of room temperature is enough to provide that energy.
What always results in a chemical reaction?
a new compound is formed a change in temperature occurs during reaction,
Describe why the indicator reaction is pH dependent?
An indicator reaction is always pH dependent because it involves hydrogen. During the reaction, hydrogen ions are either released or captured during the process.
Will the temperature in a reaction always go up?
Exo- means out Endo- means in. In an Exothermic reaction thermal energy is released (goes out) and in an Endothermic reaction Thermal energy is taken up, transferring into chemical energy (goes in). So, to answer your question, no, the temperature does not go up in both an exothermic and an endothermic reaction.
What substance is always made in a chemical reaction?
Reactants
Is boiling always a sign of a chemical reaction?
No, boiling is not always a sign of a chemical reaction.

An indicator reaction is always pH dependent because it involves hydrogen. During the reaction, hydrogen ions are either released or captured during the process.
Is burning of fuel in a cutting torch a chemical reaction?
Yes, burning of fuel is always a chemical reaction.
What is always conserved in a chemical reaction?
mass
Will the temperature in a reaction always go up?
Exo- means out Endo- means in. In an Exothermic reaction thermal energy is released (goes out) and in an Endothermic reaction Thermal energy is taken up, transferring into chemical energy (goes in). So, to answer your question, no, the temperature does not go up in both an exothermic and an endothermic reaction.
What is always formed during a chemical reaction?
a chemical reaction always converts reactants to products. Products are always formed otherwise it's not considered a chemical reaction.
What substance is always made in a chemical reaction?
Reactants
Is the rate of a chemical reaction dependent of temperature?
In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
In a balanced chemical reaction the total mass of the products always equals the total what?
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
