Which of the following can be formed by physically combining pure substances?a. an element c. a compound b. a mixture d. all of the above Weegy: It is true.The formula for Density is Mass divided Volume.

Explanation:

It is B. a mixture

Explanation:

A is wrong because an element is part of a compound and can't be physically mixed, C is wrong because atm don't jin by just physically mixing then there must be a change in smething at the physical level

also correct on edg.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

is there any options? maybe im just not seeing them but i need the options to
