Which of following is incorrect? A. Beryllium oxide - Amphoteric nature
B. Potassium superoxide - Basic nature
C. Carbon monoxide - Acidic nature
D. Bismuth Oxide - Basic nature​

C: Carbon monoxide - Acidic nature

Explanation:

A) Beryllium is not soluble in water but yet it reacts with an acid and a base. Therefore, since it exhibits both basic and acidic nature, we say it is Amphoteric in nature. Thus it is correct

B)potassium super oxide has the formula KO2. It reacts with acid to form salt called potassium chloride. Thus, it is basic in nature.

C) Carbon monoxide does not react with acids or bases. Thus, it doesn't show either an acidic or basic property and we say it is a neutral oxide. This option is incorrect

D) Bismuth oxide is a basic oxide because it displays properties of a base. This options is correct

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

answer: they produce more slow than unicellular organisms.
