This kind of questions cannot be open because there might be many different answers depending of the focus.

In fact, I found the set of options that comes with this questions. This is:

A. behavior of ions.
B. molecular bonding.
C. molecular shape.
D. molecular motion.

Of course, the answer is the option D. molecular motion.

And, of course, you need an explanation.

It is good to know that the word kinetic refers to motion, so definetly kinetic molecular theory is a theory about the motion of the molecules.

With that you likely had been able to answer the question. But it is good to know what the molecular theory is.

The molecular kinetic molecular theory explains the properties and behavior of the gases in terms of the motion of its particles (molecules) making several assumptions about the energy, size and motion of such particles.

Zinc Sulfide reacts with oxygen according to the reaction:

zhuklara [117]

The amount in moles of the excess reactant left is 0.5 mole

<h3>Balanced equation</h3>

2ZnS (s) + 3O₂(g) --> 2ZnO (s) + 2SO₂(g)

From the balanced equation,

2 moles of ZnS reacted with 3 moles of O₂

<h3>How to determine the excess reactant</h3>

From the balanced equation,

2 moles of ZnS reacted with 3 moles of O₂

Therefore,

4.2 moles of ZnS will react with =(4.2 × 3) / 2 = 6.3 moles of O₂

From the calculations made above, we can see that only 6.3 moles of O₂ out of 6.8 moles given, is required to react completely with 4.2 moles of ZnS.

Thus, ZnS is the limiting reactant and O₂ is the excess reactant.

<h3> How to determine the mole of the excess reactant remaining</h3>

The excess reactant is O₂. Thus the mole remaining after the reaction can be obtained as illustrated below:

Mole of O₂ given = 6.8 moles
Mole of O₂ that reacted = 6.3 moles
Mole of O₂ remaining =?

Mole of O₂ remaining = (Mole of O₂ given) - (Mole of O₂ that reacted)

Mole of O₂ remaining = 6.8 - 6.3

Mole of O₂ remaining = 0.5 mole

QUESTION 14

AveGali [126]

Within each functional group, the boiling points of members of the group vary according to molecular weight. Therefore, one cannot deduce any functional group from boiling points.

Organic compounds are divided into families called homologous series. Each homologous series has a functional group common to all the members of the series. As a result of this, the chemical properties of all the members of the homologous series are similar.

However, the boiling points of the members of a homologous series vary according the their molecular weights. As such, boiling points can not be used as evidence to classify substances into any particular homologous series.

Summarily, one cannot deduce any functional group from physical properties.

Today, we have seven major continents. However, most geologists don't think it was like this 200 million years ago. They think t

Oksanka [162]

Yeah this is option A one supercontinent
basically a long time ago we would have lived on pangea

Eventually this would split into two and we would get Gondwana and also Laurasia, so thechnically option two would be a possible choice but option A is the most possible choice.
