Why do reactants undergo an increase in temperature even though energy is emitted?

During the reaction, energy is initially used and the temperature is initially raised. Only near the end of the reaction does the energy "flow out."

The substance which undergo chemical change in areaction are called?
The initial substances in a chemical reaction are called reactants.
What is the name given to chemicals before they undergo chemical reactions?
They are reactants.
What does undergo physical or chemical changes mean?
if during a change the chemical composition of the reactants change or any new products are formed then the reactant is said to undergo chemical change.if the state, color, phase or any other physical properties of the reactant change without any change the chemical composition of the reactants or formation of any new substances then it is said to undergo physical change
Do elements tend to undergo chemical reactions that decrease stability?
Elements tend to undergo chemical reactions that increase stability.
What happens to the volume of gas or liquid s the temperature of a gas or liquid increases?
When heat is added to the system, we increase the average kinetic energy of molecules making up that system. When we increase the temperature, molecules undergo more rapid collisions and therefore takes up more volume. Molecules in solid state of matter has the least kinetic energy.
What is a substances that undergo a chemical change?
Substances that undergo chemical change are called reactants.
The substance which undergo chemical change in areaction are called?
The initial substances in a chemical reaction are called reactants.
What is the name given to chemicals before they undergo chemical reactions?
They are reactants.
What happens to an object temperature when it gets more thermal energy?
Either the object's temperature will increase - or, the object will undergo a phase change (for example, from solid to liquid), in which case the temperature will stay the same.
The ability of plants to undergo photosynthesis is a property?
The ability of plants to undergo photosynthesis is a chemical property. This process involves the production of new substances from the reactants.
Does gas undergo an exothermic or endothermic reaction?
too many variables. your question is vague. what is the composition of the gas? what is/are the compositions room temperature states? what are the reactants within this reaction? please refine your questions and ask again

The reactants in an enzymatic reaction are called what?
In a chemical reaction the actual reactants are also called the starting materials or interactants. These are the materials necessary for the reaction to happen and undergo chemical change.
Does the bombardier beetle shoot a boiling-hot liquid at its enemies?
Yes the bombardier beetle can. When threatened, the beetle contracts muscles that force the two reactants through valved tubes into a mixing chamber containing water and a mixture of catalytic enzymes. When combined, the reactants undergo a violent exothermic chemical reaction, raising the temperature to near the boiling point of water.
How are reactants and products related?
they both involve important things
Do elements tend to undergo chemical reactions that decrease stability?
Elements tend to undergo chemical reactions that increase stability.
The elements or compounds produced by a chemical reaction are known as what?
The substances produced by a chemical reaction are known as Products. The substances that are reacted are the Reactants.
