If we compare a mole of carbon atoms to a mole of oxygen atoms, which sample will contain more atoms?.
Alex Ar [27]

Since 1 mole of any element contains 6.0221023 atoms, a mole of carbon and a mole of oxygen will have the same number of atoms.

<h3>Is a mole of oxygen equivalent to a mole of carbon?</h3>

Answer and justification The molar mass of carbon differs from the molar mass of oxygen, hence this assertion is untrue. As a result, one mole of oxygen and one mole of carbon cannot have the same mass.

<h3>What kind of link unites carbon and oxygen?</h3>

A polar covalent link between carbon and oxygen is known as a carbon-oxygen bond. With six valence electrons, oxygen likes to either share two of them in a bond with carbon, leaving the remaining four unoccupied.

What would you predict about a chemical that has a hydrogen ion concentration of 1×10 to the -12
KonstantinChe [14]

Answer:

It is basic.

Explanation:-

Given hydrogen ion concentration [H+] = 1×10^-12

Using the formula

pH = - log [H+]

= - log [ 1 x 10^-12]

= 12

Since the pH is more than 7, the chemical is basic
