The  molarity of the solution is 0.1625M.

<h3>What do you meant by Molarity</h3>

Molarity is the amount of a substance in a certain volume of solution. Molarity is  defined as the moles of solute per litres of a solution .

Molarity → no of moles / Volume (L)

SI unit of Molarity is M or mol/ L

We have given here the mass of solution is 3.10×10²g .

molality of the solution is 0.125m

Molality → no of moles / mass in kg

→  0.125×3.10×10²/ 1000

→ no.of moles = 0.0162

For  molarity we can assume volume as 1000 ml .

Molarity = 0.0162×1000/ 100

 Molarity →0.162 M.

So, the molarity of solution will be 0.162M.

Classify each element as a metal, nonmetal, or semimetal. br in cr ca drag the appropriate items to their respective bins. view
goldenfox [79]
Below is the distribution of given elements and additional elements in their respective bins.

Iron, Magnesium, Aluminium, Calcium, Chromium and Indium are classified as Metals due to their hardness, conduction of current and heat, Solid state, formation of metallic bonding and prefers to form cations e.t.c

Oxygen, Neon and Bromine are classified as non-metals. Non-metals are mostly gases except for Bromine. They are highly volatile and prefers to form anions.

Semimetals are those metals which have both properties of metals and non-metals and are also called as metalloids.

Answer:

Answered

Explanation:

1)False,  electron carriers are not  located at ribosomes.

2) True, ATP is the common intermediate between catabolic and anabolic pathways.

3)False,  ATP is used for the long-term storage of energy and so is often not found in storage granules.

4) True, Anaerobic organisms are capable of generating ATP via respiration.

5) True , ATP can be generated by the flow of protons across protein channels.

A teacher puts two tablets in a glass of water. The teacher
ehidna [41]

This question is incomplete because the options are missing; here are the options:

Which of the following is LESS dense than water?

The spoon

The glass

The tablets

The bubbles

The correct answer to this question is The bubbles

Explanation:

In general, the density of materials and substances affects their buoyancy. This implies in water less dense materials will float and those with higher density will sink. In the situation presented, the only element that is less dense than water are bubbles; this is shown by the movement of the bubbles as these originate in the bottom of the glass of water but they rise to the surface, which shows they are less dense than water.

Which of the following are strongly hydrogen bonded in the liquid phase? A) nitrilesB) esters C) secondary amides D) acid chlori
-Dominant- [34]

Answer: Option (C) is the correct answer.

Explanation:

Chemical formula of a secondary amide is R'-CONH-R, where R and R' can be same of different alkyl or aryl groups. Here, the hydrogen atom of amide is attached to more electronegative oxygen atom of the C=O group.

Therefore, the hydrogen atom will be more strongly held by the electronegative oxygen atom. As a result, there will be  strongly hydrogen bonded in the liquid phase of secondary amide.

Whereas chemical formula of nitriles is RCN, ester is RCOOR' and acid chlorides are RCOCl. As no hydrogen bonding occurs in any of these compounds because hydrogen atom is not being attached to an electronegative atom.

Thus, we can conclude that secondary amides are strongly hydrogen bonded in the liquid phase.
