What is a thermochemical reaction?
A thermochemical reaction is a chemical reaction that involves the absorption or release of heat. This heat exchange is responsible for changes in the temperature of the system during the reaction. Thermochemical reactions are important in understanding processes such as combustion, photosynthesis, and digestion.
What chemicals control changes from childhood to adulthood?
Hormones released by the endocrine system cause the changes associated with puberty.
What are various types of change?
Basically there are 3 types on changes in chemisty. 1. Inorganic Changes-reaction of elements and compounds 2. Organic Changes-reactons of mineral oils and its compound. 3. Bio-chemical changes-reactions involves protein, enzyme and hormones.
What type of reaction is used in calorimetry?
Calorimetry typically involves measuring heat changes in a system during a chemical reaction, making it an example of an exothermic or endothermic reaction. These reactions release or absorb energy in the form of heat, which can be quantified to determine the heat capacity or enthalpy change of the reaction.
What is the key characteristic of an oxidation-reduction reaction?
The key characteristic of an oxidation-reduction reaction is the transfer of electrons between reactants. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. This transfer of electrons results in changes in the oxidation states of the substances involved.
What type of reaction involves changes in the electrons of an atom?
all of them. that's what a reaction is.
Is An apple turning brown and food burning on stove is this a physical change?
An apple turning brown is a chemical change because it involves a reaction that changes the chemical composition of the apple. Food burning on the stove is also a chemical change as it involves a combustion reaction that changes the chemical composition of the food.

Thermochemical reactions are important in understanding processes such as combustion, photosynthesis, and digestion.
How can one identify redox reactions?
Redox reactions can be identified by looking for changes in oxidation states of elements involved in the reaction. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. If there is a change in oxidation states of elements in a chemical reaction, it is likely a redox reaction.
What is a reaction in a chemical reaction in science?
A reaction in a chemical reaction refers to the transformation of one or more substances into new substances with different properties. This process involves the breaking and formation of chemical bonds between atoms or molecules. Energy changes may also occur during a chemical reaction.
What does the SN1 reaction coordinate diagram illustrate?
The SN1 reaction coordinate diagram illustrates the energy changes that occur during a nucleophilic substitution reaction where the rate-determining step involves the formation of a carbocation intermediate.
An acid-base titration involves?
An acid-base titration involves slowly adding a solution of known concentration (titrant) to a solution of unknown concentration (analyte) until the reaction is complete. The endpoint is reached when the indicator changes color or the pH reaches a specified value. This allows for determination of the concentration of the analyte.
The endocrine system produces chemicals that?
Good question......................................................What? Am I supposed to answer it? Fine! The endocrine system consists of glands that, through the secretion of hormones, regulate just about every aspect of your body in very specific ways. Almost every cell and organ of the body is regulated by the endocrine system. There! Now go away!!!!!!!!!!!!!!!!!!the part in bold is the answerthis person is fairly mean:)
How can one determine redox reactions?
Redox reactions can be determined by looking for changes in oxidation numbers of elements involved in the reaction. Oxidation involves an increase in oxidation number, while reduction involves a decrease. If there is a change in oxidation numbers, it indicates a redox reaction.
An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a chemical reaction, it involves rearrangement of electrons in the outer shell to form new chemical bonds. On the other hand, if it undergoes a nuclear reaction, it involves changes in the atomic nuclei, resulting in the formation of different elements or isotopes. To determine whether it was a chemical or nuclear reaction, observe whether there are changes in the electron configuration or in the atomic number and mass of the atom.
What happens during a reduction/oxidation reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron
What chemicals control changes from childhood to adulthood?
