Chemistry

Answer:

Option (1)

Explanation:

Sinkholes are one of the distinct geological features. These are circular depressions that are formed due to the collapse of the ground surface. These are formed in the region where the rocks are either carbonate (limestone), salt rocks or gypsum which is easily dissolved when it comes in contact with the groundwater flow. It results in the formation of caves. The sinkholes are characterized by the presence of karst topography above them on the surface and sinkholes are often considered to be one of the main features of the karst topography.

Thus, the correct answer is option (1).

Answer:

Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions.

Select the reason why two molecules of benzaldehyde cannot react via the aldol condensation.
Lesechka [4]
Benzaldehyde or C6H5CHO would not undergo the aldol condensation because it does not contain an alpha-hydrogen in its structure. Aldol condensation is a type of reaction that happens between an enolate and an aldehyde or ketone leading to a alkene that has a planar structure. The lack of an alpha-hydrogen would not allow for it to undergo such process since it cannot enolize. Benzaldehyde undergoes a nucleophilic reaction known as Claisen-Schmidt condensation. It has somehow same mechanism of the aldol reaction however, the nucleophilic attack on the carbonyl happens even without the alpha-hydrogen but with an enolate that is from a ketone.

How many moles are in 1.05 g of gold (Au)?
Wittaler [7]

Answer:

0.005 mol

Explanation:

Moles is denoted by given mass divided by the molecular mass ,  

Hence ,  

n = w / m

n = moles ,  

w = given mass ,  

m = molecular mass .

From the question ,

w = given mass of Gold = 1.05 g ,

m = molecular mass of Gold = 197 g/mol

<u>Hence , moles can be calculated as -</u>

n = w / m = 1.05 g / 197 g/mol = 0.005 mol

Which of these is a unique property of bases?
tatuchka [14]

Answer:

A. Feels slippery

Explanation:

Bases are the only types of compounds that have a slippery feel.

B is <em>wrong</em><em>.</em> Most bases do not contain carbon, but organic compounds always do.

C is <em>wrong</em>. Aqueous solutions of bases conduct electricity, but so do aqueous solutions of salts.

D is <em>wrong</em>. Most bases have a bitter taste. Acids have a sour taste.

Calculate the ph of a 0.10 m solution of hypochlorous acid, hocl. ka of hocl is 3.5×10−8 at 25 ∘c. express your answer numerical
Viktor [21]

Answer:

4.23.

Explanation:

<em>∵ pH = - log[H⁺].</em>

<em>For weak acids:</em>

∵ [H⁺] = √(ka)(c).

∴ [H⁺] = √(3.5 × 10⁻⁸)(0.10 M) = 5.92 x 10⁻⁵.

∴ pH = - log[H⁺] = - log(5.92 x 10⁻⁵) = 4.2279 ≅ 4.23.
