In a science lab, cash mixes two clear liquids together in a beaker. bubbles are produced, and a white solid forms and settles to the bottom. he plans to heat the beaker over low heat and make more observations. which statement is most likely correct? a physical change occurred, so if cash heats it, the white solid will dissolve to form the original mixture of clear liquids. a physical change occurred, so even if cash heats it, the white solid will remain. a chemical change occurred, so if cash heats it, the white solid will dissolve to form the original mixture of clear liquids. a chemical change occurred, so even if cash heats it, the white solid will remain.

The correct option is this: A CHEMICAL CHANGE OCCURRED, SO EVEN IF CASH HEAT IT, THE WHITE SOLID WILL REMAIN.T

There are two major types of change in chemistry, physical and chemical change. A physical change is one which is easily reversible and in which no new substance is formed while a chemical change is one which is not reversible and in which new substances are formed. From the information given in the question above, we can conclude that a chemical change has occurred because a gas is given off and a precipitate [which is a new substance that is different from the reactants] is formed.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

it is the most commonly accepted one
