A sample of a monoprotic acid (ha) weighing 0.384 g is dissolved in water and the solution is titrated with aqueous naoh. if 30.

Students dealing with ionic bonds comprehend better how to convey what the model should showcase.

Explanation:

• Upon dissolving ionic compounds in water, the compounds separate into their constituent ions via a process called dissociation.
• The ions become attracted to water molecules, which carry a polar charge.
• If the pull between the ions and the water molecules is strong enough to disband the ionic bonds, the compound dissolves.
• The ions disperse in the solution, each surrounded by water molecules to inhibit reattachment.
• The ionic solution forms an electrolyte, allowing it to conduct electricity.
• In contrast, while covalent compounds do dissolve in water, they separate into molecules, not individual atoms.
• Water acts as a polar solvent, yet covalent compounds are generally nonpolar.
• This implies that covalent compounds often do not dissolve in water and instead form a distinct layer on top of the water.

Explanation:

It is established that 1 gram is equivalent to 1000 milligrams. We can express this mathematically in the following way.

              or

Thus, to convert grams to milligrams, we simply multiply the number by 1000. Conversely, for converting milligrams back to grams, we divide by 1000.

Answer: The molecular formula for the specified organic compound is

Explanation:

The combustion reaction of a hydrocarbon comprising carbon, hydrogen, and oxygen follows:

where 'x', 'y', and 'z' denote the subscripts of Carbon, hydrogen, and oxygen respectively.

The information provided includes:

Mass of

Mass of

From our knowledge:

Molar mass of carbon dioxide is 44 g/mol

Molar mass of water is 18 g/mol

For determining the amount of carbon:

In carbon dioxide weighing 44 g, 12 g of carbon is found.

Hence, in 39.61 g of carbon dioxide, grams of carbon will be found.

For finding the mass of hydrogen:

In water weighing 18 g, 2 g of hydrogen can be found.

Thus, in 9.01 g of water, grams of hydrogen will be present.

Mass of oxygen in the compound is given by (13.42) - (10.80 + 1.00) = 1.62 g

To derive the empirical formula, the following steps must be followed:

• Step 1: Convert the indicated masses into moles.

Moles of Carbon =

Moles of Hydrogen =

Moles of Oxygen =

• Step 2: Calculating the ratio of moles of the respective elements.

To find the mole ratio, each mole value is divided by the smallest amount of moles calculated, which is 0.10 moles.

For Carbon =

For Hydrogen =

For Oxygen =

• Step 3:Using the mole ratios as subscripts.

The ratio of C: H: O = 9: 10: 1

Therefore, the empirical formula for the mentioned compound is

To ascertain the molecular formula, it is necessary to find the valency, which is multiplied by each element to derive the molecular formula.

The equation to determine the valency is:

Given the data:

Molecular formula mass = 268.34 g/mol

Empirical formula mass = 134 g/mol

Substituting the values into the aforementioned equation yields:

By multiplying this valency with each element's subscripts from the empirical formula, the results are:

Consequently, the molecular formula for the given organic compound is .
