What results in a chemical change?
Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermicreactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science ofchemistry. When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. An example of a chemical change is the reaction between sodium and water to produce sodium hydroxide and hydrogen. So much energy is released that the hydrogen gas released spontaneously burns in the air.
If chemical energy can be used to produce kinetic energy what is an example of using chemical energy to produce kinetic energy?
Your car.
What are some fast chemical reactions?
1. Skin and respiratory allergic reactions 2. Baking soda and vinegar 3. Caustic soda exposed to liquid 4. Many different forms of acids exposed to almost everything will cause an immediate chemical reaction
Is leaves produce oxygen a physical or a chemical change?
Its a chemical change. Leaves breathe in carbon dioxide. They use it to carry out the process of photosynthesis that is preparation of food for growth. Chemical changes involving salts, water, carbon dioxide take place in the presence of sunlight that results in the liberation of oxygen into the atmosphere. At night however in the absence of sunlight it breathes in oxygen to prepare food, since photosynthesis is not possible due to absence of sunlight.
Which action forms a different chemical substance?
Any chemical reaction produce a new substance.
What do rockets use to produce energy?
Rockets use chemical reactions, typically involving liquid or solid propellants, to produce energy for propulsion. These reactions create hot gases that are expelled through a nozzle at high speeds, generating thrust that propels the rocket forward.
Do chemical reactions produce new atoms?
No, chemical reactions do not produce new atoms. Atoms are rearranged in chemical reactions to form new substances, but the number of atoms remains constant before and after the reaction. This is known as the Law of Conservation of Mass.
What type of reaction is involved in many of the chemical reactions of photosynthesis?
Many of the chemical reactions in photosynthesis are redox reactions, involving both reduction and oxidation processes. In photosynthesis, carbon dioxide is reduced to sugars, while water is oxidized to produce oxygen.
What chemical reactions explode?
Chemical reactions that produce a rapid release of gas, heat, and light can lead to explosions. This can happen when highly reactive substances come in contact with each other, such as the reaction between an oxidizer and a fuel. Reactions involving energetic materials like nitroglycerin or TNT can also result in explosive outcomes.
What kinds of chemical reactions produce water?
Chlorine
Do all collisions produce chemical reactions?
It is not mandatory.
Do catalyst produce chemical reactions?
yes chemical reactions in order to induce a chemical reaction that might normally take a long time
Chemical reaction that produces heat?
Chemical reactions that produce heat (or energy) are known as Exothermic Reactions. (Example: combustion of fuels)
What is the ability to combine and react?
This is the aptitude of chemical elements to do chemical reactions and to produce compounds.
What changes do chemical reactions produce?
There are a huge number of chemical reactions, and the outcomes can vary widely from something that can hardly be noticed to a violent explosion.
What reactions produce electrons?
Oxidation reaction.
Do a chemical reaction produce heat and light?
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
