14. $MgCl_{2} + Na_{2}O$

Both are ionic compounds and therefore oxidize to certain states. Mg has an oxidation state of +2, Cl has an oxidation state of -1, Na has an oxidation state of +1, and O has an oxidation state of -2.

15. MgO + NaCl

Using the same oxidation states, you write the formulas of your products.

16. $MgCl_{2} + Na_{2}O -\ \textgreater \ MgO + 2NaCl$

You know that you must have the same number of elemental atoms on one side of the reaction as you do on the other. With this balanced equation, you see that both the left and right sides have 1 Mg, 2 Cl, 2 Na, and 1 O.

As a bonus, you can also add in the states of the compounds:

$MgCl_{2} (aq) + Na_{2}O (aq) -\ \textgreater \ MgO (s) + 2NaCl (aq)$

17. This is a double replacement reaction (also called a metathesis reaction, or a double displacement reaction), because one element within one compound basically switches places with the element in the other compound. It is also a precipitation reaction, because a precipitate (MgO) is formed.

Hope this is helpful!

Question No.14:

The formulas of reactants: MgCl2 and Na2O.

Explanation:There are two reactants in this reaction:Magnesium Chloride whose formula is MgCl2. It is present in liquid form. It contains one magnesium atom and 2 chlorine atoms.Sodium oxide whose formula is Na2O. It is present in solid form. It contains one sodium atom and 2 oxygen atoms.Question no. 15

The formulas of products are: MgO and NaCl.

Explanation:

Reaction equation:

MgCl2 + Na2O → MgO + 2NaCl

Two products are formed:

One product is magnesium oxide which is present in solid form. Its formula is MgO and it contains 1 magnesium atom and one oxygen atom.

The second product is sodium chloride. Two molecules of sodium chloride are produced in this reaction and its formula is NaCl.

Question no 16

The balanced chemical equation of this reaction:

MgCl2+ Na2O → MgO + 2NaCl

Explanation:A balanced chemical reaction means the number of atoms and molecules in reactants should be equal to the number of atoms and molecules of the products.In this reaction, 1 molecule of MgCl2 and 1 molecule of Na2O reacts to form one molecule of MgO and 2 molecules of NaCl. All the atoms and molecules are balanced on both sides.Question no. 17.

The type of above reaction is a double replacement reaction.

Explanation:This reaction is also known as a double displacement reaction and metathesis reaction.In this reaction, one molecule reacted and contributed to form two products. For example, MgCl2 switches to form MgO and NaCl two products.In this reaction, MgO is precipitated.

Answer from: Quest

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
