It seems that the question is lacking hypothesized structures, which are provided in Figure A

Answer:

Option A has bond angles that have the highest strain beyond known tolerance

Explanation:

Note: Please find the complete question in the attachment

The hypothesized structures in the options were the proposed structures of benzene in the mid 19th century by Ladenburg (1869), Thiele (1899), Armstrong (1887), and Kekule (1865) respectively

Option A suggests sp3 hybridization of the carbon atom. sp3 hybridized atoms are oriented at 109.5° to be stable. The structure suggests that bond angles between C-C bonds are 60° and 90°, these bond angles are well beyond the known tolerable angle strain.

Options B and D (currently accepted structures of benzene) are sp2 hybridized and their bonds angle is 120°, which is the optimal angle for sp2 hybridized atom. Option C also suggests sp2 hybridized carbon, so their will also be no ring strain in it. But it is not an accepted structure as it was suggested to contain radical like properties by Armstrong.

When magnesium reacts with chlorine, magnesium ions, Mg2+, and chloride ions, Cl−are formed. In this reaction, magnesium atoms A
Slav-nsk [51]

<u>Answer:</u> In the reaction, magnesium atoms lose electrons.

<u>Explanation:</u>

An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal or a metal reacts with a polyatomic ion or a reaction between two polyatomic ions takes place.

Magnesium is 12th element of the periodic table having electronic configuration of 1s^22s^22p^63s^2

This element will loose 2 electrons to form Mg^{2+} ion

Chlorine is 17th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^5

This element will gain 1 electron to form Cl^- ion

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

The ionic compound formed is MgCl_2

Hence, in the reaction, magnesium atoms lose electrons.

six different aqueous solutions are represented in the beakers below, and there total volumes are noted. (a) which solution has
wolverine [178]

The molarity of the solutions are as follows:

  • solution B has the highest molarity
  • solutions A, D and F have the same molarity
  • solutions A and C are mixed together have a lower molarity than B
  • solution F and D will have the same molarity
  • Volume of water required to be evaporated is 8.3 mL

<h3>What is molarity of a solution?</h3>

The molarity of a solution is the amount in moles of a substance present in a given volume of solution.

From the image of the solution given:

  • solution B has the highest molarity
  • solutions A, D and F have the same molarity
  • when solutions A and C are mixed, the resulting solution have a lower molarity than B
  • solution F and D will have the same molarity after 75 mL and 50 mL of water are added to each respectively
  • the molarity of B is 12/50 = 4/16.7. Volume of water required to be evaporated = 25 - 16.7 = 8.3 mL

Therefore, the molarity of the solutions depends on the moles of substance present per given volume of solution.
