Answer:

adding water to an anhydrous compound forms a hydrate.

Explanation:

The statement which correctly describes the relationship between a hydrate, water, and an anhydrous compound is adding water to an anhydrous compound forms a hydrate. The correct option is A.

Anhydrous means without water, so the compounds that do not contain water are anhydrous compounds. Some examples are sodium sulfate, hydrogen fluoride, etc.

Hydrates are the compounds that contain water as the H2O molecules. These compounds lose their structure if water molecules are removed from the compound.

So, when water is added to the anhydrous molecules, it converts into hydrates. An example is sodium sulfate decahydrate.

Thus, the correct option is A. Adding water to an anhydrous compound forms a hydrate.

The volume of NaOH required to titrate 50 mL of 0.0998 M butanoic acid to the equivalence point is 41.58 mL

C₄H₈O₂ + NaOH —> C₄H₇O₂Na + H₂O

From the balanced equation above,

From the question given above, the following data were obtained:

CaVa / CbVb = nA / nB

(0.0998 × 50) / (0.12 × Vb) = 1

4.99 / (0.12 × Vb)  = 1

Cross multiply

0.12 × Vb = 4.99

Answer:

the compound that has the smallest ions with the greatest charge

The compound that has the smallest ions with the greatest charge will have the strongest ionic bonds. Therefore, option C is correct.

Ionic compounds can be defined as solids formed by closely packed ions of opposite charge. An Ionic compound is commonly formed when metal combines with non-metal.

In ionic compounds, the ions are held together by ionic bonds. The ions are created by accepting or losing electrons in order to get their nearest noble gas configuration. In a reaction, the metals have a tendency to lose electrons to complete their octet while non-metals will gain electrons to fill their octet.

An ionic bond or electrovalent bond is a type of linkage generated from the electrostatic attraction between oppositely charged ions. Such a bond produces when the valence electrons of one atom are transferred permanently to another.

The more the charge on the ions and the smaller the ions stronger the ionic bond will be formed.

The mass of oxygen must react to form 3.80 mol of Al₂O₃ in the given reaction is 182 grams.

Mass of any substance will be calculated by using their moles as:

n = W/M, where

W = required mass

M = molar mass

Given chemical reaction is:

4Al + 3O₂ → 2Al₂O₃

From the stoichiometry of the reaction it is clear that,

2 moles of Al₂O₃ = obtained from 3 moles of O₂

3.80 moles of Al₂O₃ = obtained from 3/2×3.80=5.7 moles of O₂

Now we calculate the mass of oxygen of 5.7 moles as:

W = (5.7mol)(32g/mol) = 182.4 grams or 182g

Hence option (4) is correct.

As the scuba diver ascends rapidly to the surface at the given pressure, the volume of the nitrogen bubble at the surface becomes 0.021mL.

Boyle's law states that the volume V of a given quantity of gas is inversely proportional to its pressure P as long as temperature remains constant.

Boyle's law is expressed as;

P₁V₁ = P₂V₂

Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.

Given the data in the question;

We substitute our given values into the expression above to find the final volume.

P₁V₁ = P₂V₂

[tex]V_2 = \frac{P_1V_1}{P_2} \\\\V_2 = \frac{4.1atm \ *\ 5.0*10^{-6}L}{1.0atm}\\ \\V_2 = \frac{4.1 \ *\ 5.0*10^{-6}L}{1.0}\\\\V_2 = 2.05*10^{-6}L\\\\V_2 = 0.021mL[/tex]

Therefore, as the scuba diver ascends rapidly to the surface at the given pressure, the volume of the nitrogen bubble at the surface becomes 0.021mL.
