What can form as a result of a chemical reaction? what can form as a result of a chemical reaction? compounds isotopes alpha particles beta particles

Compounds

Explanation:

Chemical reactions involving more than one element mostly give rise to compounds when transfer of electrons occurs.

The compounds are as a result of the combination of the individual elements and radicals.

Isotopes occur naturally while alpha (α) and beta (β) particles are as a result of nuclear reactions.

compounds

Explanation:

A physical reaction is defined as the reaction in which a change in shape, size takes place. No new substance gets formed in these reactions.

A chemical reaction is defined as the reaction in which a change in chemical composition takes place. A new substance or compound is formed in these reactions.

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions. Example: water

Isotopes, alpha and beta particles are formed in nuclear reactions.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
