21.614 grams are found in [tex]6.5 \times 10^{22}[/tex] molecules of caffeine.

Explanation:

The chemical formula for caffeine is [tex]C_{8}H_{10}N_{4}O_{2}[/tex], the molar weight of caffeine is:

[tex]M = 8\cdot \left(12.011\,\frac{g}{mol} \right) + 16\cdot \left(1.008\,\frac{g}{mol} \right)+4\cdot \left(14.007\,\frac{g}{mol} \right)+2\cdot \left(15.999\,\frac{g}{mol} \right)[/tex]

[tex]M = 200.242\,\frac{g}{mol}[/tex]

According to Avogadro's Law, a mol of caffeine contains [tex]6.022\times 10^{23}[/tex] molecules. The number of grams contained in [tex]6.5 \times 10^{22}[/tex] molecules is determined by simple rule of three:

[tex]x = \frac{6.5\times 10^{22}\,molecules}{6.022\times 10^{23}\,molecules} \times 200.242\,g[/tex]

[tex]x = 21.614\,g[/tex]

21.614 grams are found in [tex]6.5 \times 10^{22}[/tex] molecules of caffeine.

One organism was ancestor of the other organism and both organisms lived around the same time is the conclusion made by scientist.

Fossil scientist are the specialists in studying the ancient fossils of animals and plants.

If fossils of two different species of very similar organisms are found in different layers of rock then it might be the possibility that one organism was ancestor of the other or both organisms lived around the same time. Because it is not necessary that if two species had the same organism then they have same behavior.

Hence, option (c) & (d) is correct.

Answer:

I have the lowest electronegativity of the nonreactive elements. My family name is alkali metals. I am classified as a reactive metal. I have one valence electrons.

Explanation:

Electronegativity refers to the ability of the atoms of an element to attract electrons to itself. Based on their nature, non-metals are electronegative elements whereas metal are electropositive as they have a tendency to give up their electrons rather than attract electrons to themselves.

In the periodic table of elements, non-metallic character, and hence, electronegativity increases from left to right across a period, and decreases down a group. The most electropositive element is fluorine. On the other hand, electropositivity decreases across a period from left to right but increases on going down a group. Hence, the most electropositive element is Francium. This also means that Francium is the least electronegative element,

francium belong to the group 1A of the periodic table which are the most reactive metals. The family of group 1A elements are known as alkali metals. They possess only one valence electron which they easily give up to form univalent positive ions or cations. Francium is a radioactive element.

Answer:

0.347

Explanation:

Al is the limiting reagent.

Explanation:

The stoichiometry of the reaction is such that 4 moles of Al are required for every 3 moles of diatomic oxygen. This means that if the ratio of Al to diatomic oxygen is greater than 4/3, then the oxygen is the limiting reagent. If the ratio of Al to diatomic oxygen is less than 4/3, then Al is the limiting reagent.

The problem state that the ratio of Al to diatomic oxygen is

The ration of Al to diatomic oxygen is less than 4/3, so Al is the limiting reagent.

So it would take 0.347 moles of Al to completely react with all of the oxygen, however there is only 0.32 moles of Aluminum present, so there is not enough Al to react with all of the oxygen, and so we say that the Al is the limiting reagent.

The mass of Aluminum are needed to produce 21.6 grams of Aluminum oxide (Al₂O₃) is

Mass of any element is equal to the product of its number of moles and molar mass.

For the compound, Aluminum oxide (Al₂O₃)

The atomic masses of Aluminum is 23 and oxygen is 16.

Molecular or molar mass = ( 2 × 23 ) + ( 3 × 16 ) units

M = 46 + 48 = 94 units

The mass of Aluminum in 1 mole of aluminum oxide ,46 grams in 94 grams

Mass of Aluminum in the given 21.6 g of Aluminum oxide will be;

94 grams of Aluminum oxide contains 46 grams of Aluminum.

21.6 grams of Aluminum oxide will contain ( 46 / 94 ) × 21.6 = 10.57g of Aluminum.

Therefore, 10.57g of Aluminum are needed to produce 21.6 grams of Aluminum oxide (Al₂O₃)

Answer:

the wax is a nonpolar substance that will not mix with polar water

Explanation:

Water is polar by due to the uneven distribution of charge between the hydrogen and oxygen. T=This automatically eliminates options 3 and 4.

Wax on the other hand is a non polar substance. Due to this non polar characteristic, it would not dissolve in water. The correct option is;

- the wax is a nonpolar substance that will not mix with polar water

Answer:

35 is the correct answer (c)

Answer:

In the experiment performed involving the number of liquid drops that a penny can hold, 25 drops of substance X can fit in a penny while only 12 drops of substance Y can fit on another penny because, substance X is more viscous than substance Y. Thus, the intermolecular forces present in substance X are stronger than those present in substance Y.

Explanation:

Intermolecular forces (IMF) are the forces which exist between the neighboring molecules of a a substance. These forces, though weaker than intramolecular forces which acts between neighboring atoms, they still are responsible for several differences in the physical properties of substances with comparatively similar molecular masses.

The three major types of intermolecular forces are, hydrogen bonding, dipole–dipole interactions and  London dispersion forces.

The existence of intermolecular forces in molecules of substances results in increase in melting and boiling points, surface tension,  capillary action, viscosity, as well as surface area of substances,

Viscosity, which is the resistance to flow offered by a liquid increases with increase in the intermolecular forces between the molecules of a liquid.

In the experiment performed involving the number of liquid drops that a penny can hold, 25 drops of substance X can fit in a penny while only 12 drops of substance Y can fit on another penny because, substance X is more viscous than substance Y. Thus, the intermolecular forces present in substance X are stronger than those present in substance Y.
