Why can carbon bond to many elements simultaneously? because its +4 valence forms ionic bonds because it has a natural ionic charge of "+4" because it is capable of forming multiple covalent bonds?

Option (c) is the correct answer.

Explanation:

Carbon is a non-metal and it belongs to group 14 of the periodic table.

Atomic number of carbon is 6 and its electronic distribution is 2, 4. And, in order to attain stability a carbon atom can either lose its valence electron or it can gain 4 electrons from another atom by sharing or donating.

Hence, a carbon atom is able to form a single, double or a triple bond with its own or another atom. This makes carbon atom to form multiple bonds.

Thus, we can conclude that carbon bond to many elements simultaneously because it is capable of forming multiple covalent bonds.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

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.
