Answer:

C) 3, 1, 3, 2

Explanation:

To balance the equation, start with the simple element, Fe. You need a coefficient of 2 on the product side to balance the Fe. Then balance the O. You need a coefficient of 3 on the product side to balance the O. This makes 3 Magnesium atoms that are left unbalanced. Finally, put a 3 on the Mg on the reactant side to finish, giving you coefficients of 3, 1, 3, 2.

3. Describe how the water at the equator would be different from the<br> water at the poles.
Dmitry_Shevchenko [17]

Answer:

there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis. As a result, the fresh water falling into the ocean helps decrease the salinity of the surface water in that region.

Trava [24]

Answer:

Two

Explanation:

Elements in group 16 wants to bond with elements in group IIA, the group of alkaline earth metals.

  • The bonding will make it easier for them complete their octet.
  • Elements in group 16 has 6 valence electrons.
  • To have a complete octet, they require 2 more electrons.
  • Group II elements are willing donors as they are metals.
  • For Group II elements to fill their octets, they must lose two electrons.
  • So the willingness of group II elements to lose two electrons and the readiness for group 16 elements to gain the electrons makes the desire one another.
