What else can I help you with?
what refers to reactions that give off energy as they occur?
Such reactions are called Exothermic reactions. Their change in enthalpy is negative. Such reactions are favorable at low temperature.
How can exothermic reaction be identified?
Exothermic reactions can be identified by observing an increase in temperature during the reaction. Typically, you may feel warmth being released or notice the surroundings warming up. Additionally, you can use a thermometer to measure the temperature change throughout the reaction to confirm it is exothermic.
What is an excothermic change?
An exothermic change is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature. This type of reaction gives off energy in the form of heat as the reactants are converted to products. Examples include combustion reactions and many types of oxidation reactions.
How do you distinguish exothermic and endothermic processes?
Exothermic processes release heat to the surroundings, causing a rise in temperature, while endothermic processes absorb heat from the surroundings, leading to a decrease in temperature. This distinction is often observed through changes in the energy content of a system – exothermic reactions have a negative change in enthalpy, while endothermic reactions have a positive change in enthalpy.
What is the difference between endothermic and exothermic reactions?
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
What do exothermic reactions achieve in terms of energy release and temperature change?
Exothermic reactions release energy in the form of heat, causing an increase in temperature.
How is endothermic reactions differ from exothermic reactions?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature. In contrast, exothermic reactions release heat into the surroundings, leading to an increase in temperature. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change.
What property of solution could you change to get a greater temperature change in endothermic and exothermic reactions?
Concentration.

What chemicals reactions give out heat which involves change color?
These are exothermic reactions.
What is the difference between endothermic and exothermic change?
Endothermic reactions absorb heat from the reactants, i.e , the vessel or beaker in which the reactions have happened will be cool to touch........ Whereas in exothermic reactions, Heat will be given out and the vessel will be hot to touch..........
What change releases energy into its surroundings?
Exothermic reactions release energy into their surroundings. These reactions involve the release of heat, light, or sound, resulting in a temperature increase in the surrounding environment. Examples include combustion, oxidation reactions, and many types of chemical reactions.

In a 6th grade science class what are three processes that take place that involve chemical reactions and one of them is an exothermic reaction?
Color change, change in the state of matter, change in temperature
