Which of the following statements is/are true of oxides? 1. A basic oxide is an oxide that reacts with bases. 2. An acidic oxide is an oxide that reacts with acids. 3. An amphoteric oxide is an oxide that has both basic and acidic properties

Correct option: 3

Explanation:

A basic oxide is an oxide that reacts with water to give base or reacts with acid to form salt

eg:

Sodium oxide reacts with water to produce sodium hydroxide.

Magnesium oxide gives magnesium chloride on reaction with hydrochloric acid

An acidic oxide is an oxide that reacts with water to give acid and reacts with base to give salt.

eg: Carbon dioxide gives carbonic acid on reaction with water .

Sulfur dioxide gives sulfites when reacs reacts with bases.

An amphoteric oxide is an oxide which reacts with base as well acid and it shows because metal have multiple oxidation state and they can form oxide as well hydroxide

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

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.
