Answer:

b. Fe-O

Explanation:

A way to predict melting points for ionic compounds is with electronegativity.

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

The most electronegativity difference (E.D.), the highest melting point, thus:

E.D. Al-N = 3,0 - 1,6 = 1,4

E.D. Fe-O = 3,5 - 1,8 = 1,7

E.D. W-C = 2,5 - 1,7 = 0,8

The most electronegativity difference is from Fe-O, thus, this ionic compound will have the highest melting point.

I hope it helps!

Answer:

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

What is the chemical composition of acid rain?

Yakvenalex [24]

The chemical formula depends on the type of acids it is. Acidic rain is a complex mixture of nitrous, nitric, sulfurous and sulfuric acids which all combine to lower the pH.

If you have 3.0 liters of an unknown gas, at standard temperature and pressure conditions, then you can calculate what about tha

Mariana [72]

We assume it as an ideal gas therefore we can use the ideal gas equation to solve the problem. The ideal gas equation is expressed as PV = nRT. We are given the volume, temperature and pressure. Therefore, we can solve for the amount of the gas in moles.

n = PV / RT
n = 1.00(3L) / (0.08206 atm L/mol K ) 273 K
n = 0.1339 mol
