Answer : The correct option is, (C)the number of molecules

Explanation :

When we are comparing 1 mole of oxygen gas (O_2) with 1 mole of carbon monoxide gas (CO) then we conclude that,

In 1 mole of oxygen gas (O_2), there are two number of molecules of oxygen.

In 1 mole of carbon monoxide gas (CO), there are two number of molecules (carbon and oxygen).

Hence, the number of molecules must be the same when comparing 1 mole of oxygen gas, with 1 mole of carbon monoxide gas.

The oxygen atom in a water molecule A is electrically neutral. B carries a negative electrical charge. C carries a positive elec
Klio2033 [76]

Answer: The oxygen atom in a water molecule carries a negative electrical charge.

Explanation:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Hydrogen bonding (H-bonding) is an intermolecular force having partial ionic-covalent character. H-bonding takes place between a hydrogen atom (attached with an electronegative atom e.g. O, N and F) and an electronegative atom (O,N and F).

In , H_2O , O is a highly electronegative atom attached to a H atom through a covalent bond. Therefore O atom gets partial negative charge and H atoms get partial positive charge.

Which element will only gain one electron during a chemical reaction?
Gelneren [198K]

Halogens

Explanation:

Halogens are a group of non-metals located in the seventh group on the periodic table. The will only gain one electron during a chemical reaction.

  • Halogens have a seven electrons in their outermost shell.
  • To complete the number of electrons in this shell, they need to gain an additional electron.
  • One more electron makes the halogen similar to the corresponding noble gas which is very stable.
  • Halogens are very reactive groups of elements and are highly electronegative.
  • They have a high affinity for electrons.
  • These elements are fluorine, chlorine, bromine, iodine and Astatine.
