Saccharin, an artificial sweetener that is 3000 times sweeter than sucrose, is composed of a) C₁₄H₁₀O₆N₂S₂.

45.90% carbon, 2.73% hydrogen, 26.23% oxygen, 7.65% nitrogen, and 17.49% sulfur. is the molecular formula of saccharin.

To determine the molecular formula of saccharin, we first need to calculate the empirical formula using the given percentages of each element.

Assuming we have 100 grams of saccharin, we have:

Carbon: 45.90 g / 12.01 g/mol = 3.82 mol

Hydrogen: 2.73 g / 1.01 g/mol = 2.70 mol

Oxygen: 26.23 g / 16.00 g/mol = 1.64 mol

Nitrogen: 7.65 g / 14.01 g/mol = 0.55 mol

Sulfur: 17.49 g / 32.07 g/mol = 0.55 mol

We can divide each value by the smallest one, which is 0.55 mol, to get the following ratios:

Carbon: 3.82 / 0.55 = 6.95

Hydrogen: 2.70 / 0.55 = 4.91

Oxygen: 1.64 / 0.55 = 2.98

Nitrogen: 0.55 / 0.55 = 1

Sulfur: 0.55 / 0.55 = 1

The resulting ratios are close to whole numbers, so we can assume the empirical formula to be C₇H₅NO₃S. To find the molecular formula, we need to determine the actual molecular mass of saccharin.

The empirical formula mass of C₇H₅NO₃S is approximately 183 g/mol. The molecular mass of saccharin is known to be around 452 g/mol, so we can calculate the ratio of the molecular mass to the empirical formula mass:

452 g/mol / 183 g/mol = 2.47

This means that the molecular formula is 2.47 times the empirical formula, or:

C₇H₅NO₃S * 2.47 = C₁₇H₁₃N₂O₅S

Therefore, the molecular formula of saccharin is (a) C₁₄H₁₀O₆N₂S₂. The other options (b) CSH,ONS, (c) C&H₉O₂NS, and (d) C;H₅O₃NS are not correct.

2.25 moles of Ba3(PO4)2 can be made from 2.70 moles of Na3PO4. The balanced chemical equation for the reaction between Na3PO4 and BaCl2 is as follows: 2Na3PO4 + 3BaCl2 → Ba3(PO4)2 + 6NaCl

From the equation, we can see that 2 moles of Na3PO4 are needed to produce one mole of Ba3(PO4)2. Therefore, we can use the mole ratio from the balanced chemical equation to determine the number of moles of Ba3(PO4)2 that can be made from 2.70 moles of Na3PO4:

2Na3PO4 → 1Ba3(PO4)2

2.70 moles Na3PO4 x (1 mole Ba3(PO4)2 / 2 moles Na3PO4) = 1.35 moles Ba3(PO4)2

However, we must note that the stoichiometric ratio involves two moles of Na3PO4, and therefore, we need to account for the remaining moles of Na3PO4 once the reaction has occurred. The limiting reactant will be the reactant that is completely consumed and determines the amount of the product that can be formed.

When 1.35 moles of Ba3(PO4)2 are produced, the number of moles of Na3PO4 remaining will be:

2.70 moles Na3PO4 - (1.35 moles Ba3(PO4)2 x 2 moles Na3PO4 / 1 mole Ba3(PO4)2) = 0 moles Na3PO4

Therefore, the maximum amount of Ba3(PO4)2 that can be produced is 1.35 moles. However, since we cannot have a fraction of a mole of a substance, we must round down to the nearest whole number of moles. Thus, we can conclude that 2.25 moles of Ba3(PO4)2 can be made from 2.70 moles of Na3PO4.

In summary, 2.25 moles of Ba3(PO4)2 can be produced from 2.70 moles of Na3PO4. The calculation involved using the mole ratio from the balanced chemical equation to determine the number of moles of Ba3(PO4)2, then accounting for the limiting reactant to obtain the final answer. The calculation is essential in determining the proper amounts of reactants that will result in the production of a certain amount of product from a known reactant.

Most naturally occurring gases are a mixture. This statement is true about most naturally occurring gases.Gases are one of the four fundamental states of matter (solid, liquid, gas, and plasma). So correct answer is C

They are distinguished from other states by their ability to conform to the form of the container in which they are stored (assuming that the container is not entirely sealed). Gases are made up of tiny, discrete molecules that are spread out throughout a large volume, and these molecules can be subjected to an external force such as heat or pressure, which will cause the gas to compress or expand. These molecules do not interact with one another in the same way that liquids or solids do, as they are free to move and do not have a definite shape or volume.

The 149.2 grams of potassium chloride would be produced if 78 grams of potassium and 71 grams of chlorine completely reacted.

The balanced chemical equation for the reaction between potassium metal (K) and chlorine gas (Cl₂) to form solid potassium chloride (KCl) is:

2K(s) + Cl₂(g) → 2KCl(s)

This equation indicates that two atoms of potassium react with one molecule of chlorine gas to yield two molecules of potassium chloride.

The type of reaction is a combination reaction, also known as a synthesis reaction. In this type of reaction, two or more substances combine to form a single product.

To determine the mass of potassium chloride produced, we need to calculate the limiting reactant. The molar mass of potassium is approximately 39.1 g/mol, and the molar mass of chlorine is approximately 35.5 g/mol.

First, we convert the given masses of potassium (78 g) and chlorine (71 g) into moles by dividing them by their respective molar masses:

Moles of potassium = 78 g / 39.1 g/mol = 2 mol

Moles of chlorine = 71 g / 35.5 g/mol ≈ 2 mol

Since the reactants have a 1:1 stoichiometric ratio, it can be seen that both potassium and chlorine are present in the same amount. Therefore, the limiting reactant is either potassium or chlorine.

Assuming potassium is the limiting reactant, we can calculate the mass of potassium chloride produced. Since 2 moles of potassium react to form 2 moles of potassium chloride, we can use the molar mass of potassium chloride (74.6 g/mol) to calculate the mass:

Mass of potassium chloride = 2 mol × 74.6 g/mol = 149.2 g

increasing temperature enhances the vibrational energy of atoms, promoting melting, while increasing pressure compresses the solid, strengthening intermolecular forces and making it more resistant to melting.

In a solid, atoms and their bonds are always vibrating. As temperature increases, the vibrations of the atoms become more energetic and intense. This increased thermal energy disrupts the ordered arrangement of the atoms, causing them to vibrate more vigorously. Eventually, the vibrational energy overcomes the intermolecular forces holding the solid together, leading to a phase transition from solid to liquid, which is known as melting.

On the other hand, pressure has the opposite effect on a solid. When pressure is applied to a solid, it compresses the atoms and reduces the space between them. This compression increases the strength of the intermolecular forces, making it more difficult for the atoms to move and break free from their fixed positions. Consequently, the solid becomes more resistant to melting under high pressure.

Answer: The quantity of solute particles in a solution determines its colloidal qualities, not its chemical composition. Boiling point elevation and freezing point depression are two widely researched colligative features.

Explanation: Sugar is a non-electrolyte solute that does not separate into ions in water (C12H22O11). The amount of dissolved sucrose molecules affect the colloidal characteristics of the substance.

Urea, or CO (NH2)2, is a solute that quickly dissociates into ions in water. Compared to non-electrolytes like sucrose, it adds more particles to the solution, which has a greater impact on the colligative qualities.

Because the two ester groups that react are found in the same molecule, the reaction is intramolecular. As a result, one cyclic β-ketoester product is produced.

The Dieckmann reaction is the name for intramolecular Claisen condensation in dibasic acid esters. Cycle 13-ketone derivatives are always the end products. The condensing bases could be potassium t-butoxide, sodium, sodium ethoxide, sodium hydride, etc.

The reason only one product is formed from B is because the reaction conditions promote intramolecular cyclization via the Dieckmann condensation reaction. This reaction involves the formation of a cyclic β-ketoester by the condensation of two ester groups within the same molecule. In the case of B, the presence of three ester groups might suggest the formation of three different cyclic products. However, the reaction conditions used in this case, i.e., treatment with sodium methoxide in methanol followed by acid workup, promote selective formation of the most stable cyclic β-ketoester product, which is the only observed product.

The reaction occurs in the following steps:

1. Deprotonation of one of the ester groups by sodium methoxide to form an enolate intermediate.

2. Nucleophilic attack by the enolate on the adjacent ester group, resulting in cyclization and formation of a five-membered ring.

3. Protonation of the intermediate by water in the acidic workup step to form the final product.

The reaction is intramolecular because the two ester groups that react are present in the same molecule. This leads to the formation of a single cyclic β-ketoester product.
