What Kinds of chemical changes?
Exothermic reactions. E.g. combustion, oxidation
What are two main kinds of changes that can observe when chemical reactions occur?
a precipitate is a solid that forms during a chemical reactions
What are some kinds of chemical changes that release energy?
Some examples of chemical changes that release energy include combustion reactions, oxidation reactions, and certain types of nuclear reactions. These reactions typically involve the breaking of chemical bonds and the formation of new, more stable bonds, resulting in the release of energy in the form of heat or light.

What are some kinds os chemical changes that release energy?
Some examples of chemical changes that release energy include combustion reactions (burning of fuel), oxidation reactions (rusting of iron), and exothermic reactions such as the reaction between acids and bases. These reactions typically result in the production of heat, light, or sound.
What is one other change in chemical changes?
There are many different kinds of chemical reactions, which involve many different kinds of chemical changes. All of these changes are observable, but some are more easily observable than others. Fire is an example of a chemical change that is extremely obvious and easily observed. When a piece of wood burns, it is changed into ash, as well as gases which are temporarily visible in the form of flame. We observe a dramatic change in temperature, since fire produces a lot of heat. Solid logs can be turned into gaseous carbon dioxide and water vapor, along with ashes and various other combustion products. But fire is not the only kind of chemical reaction. You can take two transparent aqueous solutions, mix them together, and have a chemical reaction take place that is invisible to the eye, but which can be analysed with various tests or equipment. One protein can be transformed into another protein, and both types of protein can look exactly the same. Chemical identity can be very subtle. Some chemical reactions involve visible changes of color, but most do not. Chemical reactions can produce lots of heat, or very little heat (but with a sensitive thermometer, you can detect even small changes in temperature). Chemical reactions can cause a change of phase (as from solid to gas) but they usually don't. Chemical reactions can alter solubility, so that an insoluble product is formed, which as a result causes a visible precipitate. There are many other possible results of a chemical reaction.
What kinds of chemical reactions produce water?
Chlorine
Breaking down food to get energy requires that what kinds of chemical reactions take place?
During the process of breaking down food to get energy, chemical reactions such as catabolic reactions occur. These reactions involve the breakdown of complex molecules into simpler ones, releasing energy in the process. Key catabolic reactions include glycolysis, the citric acid cycle, and oxidative phosphorylation.
Difference between chemical and physical changes?
a physical change is the form of matter but not in its chemical identity or is when the state or shape of matter is changed.physical change is reversable or temporary while a chemical is permenent or cannot be reversed.a chemical change is a change in which one or more kinds of matter are transformed into a new kind of matter.
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
What are the two main kinds of changes that can occur when chemical reactions occur?
color change. thats the one i know but i dont know the other one unless its gas formation
