Which of the following does NOT take place in a chemical reaction? a-new substances are formed b-neutrons are released c-energy is released or absorbed d-reactants disappear
I suppose the answer is b but I can think of some nuclear reactions in which neutrons are released.
To determine which of the given options does NOT take place in a chemical reaction, let's examine each option.
a) New substances are formed: This is a characteristic of a chemical reaction. When a chemical reaction occurs, the reactants combine or rearrange their atoms to form new substances with different chemical properties.
b) Neutrons are released: This option is not a general characteristic of chemical reactions. Neutrons are subatomic particles found in the nucleus of atoms, and their release typically occurs in nuclear reactions rather than chemical reactions.
c) Energy is released or absorbed: This is another characteristic of chemical reactions. During a chemical reaction, energy can be either released or absorbed, depending on whether the reaction is exothermic (releases energy) or endothermic (absorbs energy).
d) Reactants disappear: This is also a characteristic of chemical reactions. The reactants are consumed during the reaction, and their concentrations decrease as the reaction progresses.
Considering all the options, the correct answer is b) Neutrons are released, as it is not a characteristic typically observed in chemical reactions.
