What else can I help you with?
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Is reactants to products endothermic?
Not always. In a chemical reaction, the process can be either endothermic or exothermic. Endothermic reactions absorb heat from the surroundings, while exothermic reactions release heat into the surroundings. The specific reaction will determine whether it is endothermic or exothermic.
What does chemical weathering always form?
Chemical weathering always forms new minerals through the breakdown and alteration of pre-existing rocks due to chemical reactions with water, oxygen, or other substances in the environment.
Do chemical reactions always make new substances?
No all chemical reactions do not make new things because if you do a chemical reactions using two of the same things e.g carbon dioxide + carbon dioxide you are not making anything else so no not all chemical reacions make new things
What Is always involved in hydrolysis reactions.?
Hydrolysis reactions always involve the breaking of chemical bonds through the addition of water. In these reactions, water molecules split into hydroxide (OH⁻) and hydrogen ions (H⁺), which then participate in the reaction to convert larger molecules into smaller components. This process is essential in various biological and chemical systems, such as the digestion of food and the breakdown of polymers.
Why do chemical reactions always involve a chemical change?
Chemical bonds always break in chemical reactions, causing changes in energy.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Why do reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
Do Chemical reactions involve the interplay of the electrons of the reacting chemical?
always.
Do chemical reactions always involve changes in energy?
no
What type of reactions always release energy?
exothermic reactions
What changes are always involved in chemical reactions?
In a chemical reaction, changes in the arrangement of atoms and bonds occur as new substances are formed. Additionally, changes in energy levels, such as absorption or release of heat or light, are also common in chemical reactions. Moreover, changes in properties, such as color, odor, or state of matter, can often be observed as a result of a chemical reaction.
Is the spontaneity of reactions always associated with exothermic heat release?
No, the spontaneity of reactions is not always associated with exothermic heat release. Some spontaneous reactions can be endothermic, meaning they absorb heat from their surroundings.
Who invented chemical reactions?
Chemical reactions have always existed in nature. The study and understanding of chemical reactions has evolved over time, with early contributions from alchemists and philosophers, and further developments by scientists such as Antoine Lavoisier and John Dalton. There is no single person who can be credited with "inventing" chemical reactions.
When is a chemical not a chemical?
A chemical is always a chemical, by definition. Chemicals are substances with a distinct structure that can undergo reactions to form new substances.
Why do reversible reactions always result in chemical equilibria?
Reversible reactions reach chemical equilibrium because the forward and reverse reactions occur at the same rate, leading to a balance in the concentrations of reactants and products.
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
