Explanation:

Molar mass is the ratio of the mass to that amount of the substance. The mass of the barium nitrate in the formula unit is 23.0 grams.

The mass of a substance is the product of the molar mass of the compound and the number of moles of the compound.

Given,

Molar mass of barium nitrate = 261.35 g/mol

If, [tex]6.022 \times 10^{23}[/tex] have a mass of 261.35 g/mol then, [tex]5.30 \times 10^{22}[/tex] formula units will have a mass of,

[tex]\begin{aligned}& = \dfrac{261.35 \times 5.30 \times 10^{22}}{6.022\times 10^{23}}\\\\&= 23.0\;\rm gm\end{aligned}[/tex]

Therefore, option C. 23.0 gm is the mass of barium nitrate.

Given its small size and high polarizing power, lithium is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.

Lithium is a metal and a member of group 1 in the periodic table. It is a very small ion hence it has a different chemistry from the rest of the members of the group.

Lithium is not part of any of the biomolecules because given its small size and high polarizing power, it is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.

There are 1.56 moles of solute present in a 2300 mL solution of 0.68M MgSO4.

The number of moles of a substance can be calculated by using the following formula:

molarity = no. of moles / volume

According to this question, a volume of 2300 mL solution is contained in 0.68 M MgSO4. The number of moles is calculated as follows:

no of moles = 0.68M × 2.3

no. of moles = 1.56

Therefore, there are 1.56 moles of solute present in a 2300 mL solution of 0.68M MgSO4.

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.

Since an acidic salt solution is produced when a strong acid neutralizes a weak base, the pH of the salt solution formed when HCl is added to R2NH will be less than 7.

A neutralization reaction is the react ion between an acid and a base to form salt and water only.

Neutralization reactions can either produce a neutral solution, an acidic solution or an alkaline solution at equivalence point.

When a strong acid is added to a weak base, the pH of the salt solution formed will be less than 7.

If a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite, fizzing will occur because carbon dioxide is produced.

Effervescence observes whenever any gas tried to escape out from an aqueous solution, that's why CO₂ show effervescence.

Reaction between dolomite and acetic acid will be represented as:

MgCO₃ + 2CH₃COOH → CO₂ + H₂O + Mg(CH₃COO)₂

From the above reaction it is clear that carbon dixide gas is produced by showing the effervescence and fizzing behavior.
