Consider a mixture of soil and water and compare it to a colloid, such as milk. Which property best differentiates these two mix

tures? Soil and water is a suspension because it consists of minute particles suspended in the medium. Milk is a colloid because it consists of larger particles suspended in the medium, which start to settle when allowed to stand. Soil and water is a colloid because it consists of minute particles suspended in the medium. Milk is a suspension because it consists of larger particles suspended in the medium, which start to settle when allowed to stand. Soil and water is a colloid because it has a uniform composition. Milk is a suspension because it doesn’t have a uniform composition. Soil and water is a suspension because it consists of larger particles suspended in the medium, which start to settle when allowed to stand. Milk is a colloid because it consists of minute particles that remain suspended in the medium. Soil and water is a suspension because it has a uniform composition. Milk is a colloid because it doesn’t have a uniform composition.

Answer:

The correct statement is that soil and water is a suspension as it comprises larger particles suspended in the medium that begins to settle when permitted to stand. On the other hand, milk is a colloid as it comprises minute particles, which remain suspended in the medium.  

Explanation:

The particles in suspensions are bigger in comparison to those witnessed in solutions. They can be distributed evenly by mechanical means, like by shaking the constituents, however, the components get settled down eventually.

If you run this reaction with 15 g of CuCl2 and 20 g NaNO3, what is the theoretical yield of NaCl?
Margaret [11]

The theoretical yield of a substance is the amount of the mass that is calculated from stoichiometry. The mass of sodium chloride produced is 13.03 gms.

<h3>What is mass?</h3>

Mass of the substance is a multiplication of the molar mass and moles.

The balanced reaction is given as:

CuCl₂ + 2NaNO₃ ⇒ 2NaCl + Cu(NO₃)₂

Moles of copper chloride are calculated as: 15 ÷ 134.45 = 0.115 moles

Moles of sodium nitrate are calculated as: 20 ÷ 84.99 = 0.2353 moles

From the reaction, 1 mole of copper chloride gives 2 moles of sodium chloride so, 0.115 moles of copper chloride will produce 0.223 moles.

Similarly, 2 moles of sodium nitrate produce 2 moles of sodium chloride so, 0.2353 moles produce 0.4706 moles.

From this, it can be concluded that copper chloride is a limiting reagent and will be used to calculate the mass of NaCl.

Mass of NaCl is calculated as: Mass = 0.223 moles × 58.44 = 13.03 gms.

Therefore, 13.03 gms is the theoretical yield of sodium chloride.

Robert has pure samples of both D-ribose and D-arabinose, but he forgot to label them. He only has some nitric acid, the reagent
Sauron [17]

Answer:

Following are the responses to the given question:

Explanation:

Since HN03 is an oxidation substance D-ribose u.ith oxidized to form in rubric acid Ribose is chiral, but rubric acid is achiral because of its symmetry mirror level, Hence no infrared roster in the sample holder is observed.

Please find the attached file.

D-Arabinose, on either hand, gives optical aldaric acid with such a net optical rotation observed inside the polarimeter for diagnosis with HN03.
