Give a theoretical reason why lithium and oxygen combine in the ratio 2:1
V125BC [204]
Lithium is in the first column of the periodic table and thus can only form one bond with another atom (its ion is Li+)

Oxygen can form two bonds (as in the dioxygen O2).

Hence if you conbine Li and O it has to be Li2O.

Which substance would have the highest melting point, based on electronegativity?
kenny6666 [7]

Water, H₂O, will have the highest melting point.

Explanation:

So here we have listed the hydrides of oxygen, sulphur, selenium and tellurium.

From this elements oxygen have the highest electronegativity and as a consequence the oxigen hydride (water, hydrogen dioxide) it is able to form hydrogen bonds between molecules. So you need more energy to overcome the interactions between molecules in water that for the other compounds.

Water, H₂O, will have the highest melting point between the listed hydrides.

- How many moles of S2 are needed to produce 1.50 moles of SO2 gas? S2 + 20, ----> 2802​
matrenka [14]

Answer:

0.75 moles

Explanation:

S2 + 2O2 = 2SO2

From the reaction above,

We see that number of moles attached to S2 is 1 and number of moles attached to SO2 is 2.

Since we want to find how many moles of S2 are needed to produce 1.50 moles of SO2 gas

The answer is gotten by proportion;

Number of moles = 1/2 × 1.5 = 0.75 moles
