In each reaction box, place the best reagent and conditions from the list below.
In each reaction box, place the best reagent and conditions - 1

Answers

Answer 1
Answer: This is a two step step reaction as shown below,

Step 1:
           Epoxidation of Alkene:
                                              In first step Cyclohexene is treated with peroxybenzoic acid in the presence of Dichloromethane which results in the formation of epoxide moiety.

Step 2:
           Nucleophillic Substitution Reaction:
                                                                  In second step the epoxide formed is treated with Sodium Methoxide which acts as a nucleophile and attacks the less hindered carbon of epoxide resulting in the formation of final product as shown below.
Answer 2
Answer:

Final answer:

The best reagent and condition for a chemical reaction is dictated by the reactants at hand and the substance that you're trying to produce. For instance, to convert an alkene into an alcohol, Osmium Tetroxide (OsO4) at room temperature would be an example of an ideal reagent and condition.

Explanation:

In chemistry, when you are asked to place the best reagent and conditions in a reaction box, you are trying to predict the proper chemical, heat, or pressure conditions that will foster a certain chemical reaction. This requires understanding of substances' chemical properties, behavior under different conditions, and reaction mechanisms. For instance, if we want to oxidize an alkene into an alcohol, we would choose a reagent like Osmium Tetroxide (OsO4). In this case, OsO4 would be our 'best reagent', and room temperature may serve as the ideal condition as it generally facilitates this process. Each reagent and condition depend on the reactants you start with and the product you want at the end.

Calculate the mass of 139 cm^3 Argon at STP

Answers

Volume in liters:

139 cm³ / 1000 = 0.139 L   

molar mass Argon = 39.95 g/mol

1 mole -------- 22.4 L ( at STP )
? mole ------- 0.139 L

moles of argon :

0.139 * 1 / 22.4 = 0.00620 moles 

Mass of argon :

0.00620 * 39.95 = 0.24769 g

The compound NaOH(s) dissolves in water to yield(1) hydroxide ions as the only negative ions
(2) hydroxide ions as the only positive ions
(3) hydronium ions as the only negative ions
(4) hydronium ions as the only positive ions

Answers

Answer: Option (1) is the correct answer.

Explanation:

Sodium hydroxide is a strong base and when it is dissolved in water it completely dissociates into ions.

The chemical equation for this dissociation is as follows.

           NaOH(s) + H_(2)O(l) \rightarrow Na^(+)(aq) + OH^(-)(aq)

Therefore, we can see that sodium ions are the only positive ions and hydroxide ions are the only negative ions formed upon dissociation of NaOH in water.

Thus, we can conclude that the compound NaOH(s) dissolves in water to yield hydroxide ions as the only negative ions.

Which statement best describes the formula equation Cl2(g) + 2KBr(aq) mc014-1.jpg 2KCl(aq)+ Br2(l)?A Carbon iodide reacts with potassium bromide to form potassium carbon iodide and bromine.
B Bromine gas reacts with a solution of potassium chloride to form potassium bromide and chlorine gas.
C Potassium bromine gas reacts with liquid chlorine to form potassium chloride in solution and bromine gas.
D Chlorine gas reacts with potassium bromide to form potassium chloride in solution and liquid bromine.

Answers

The statement that describes the chemical reaction is D chlorine gas reacts with potassium bromide to form potassium chloride in solution and liquid bromide. The symbol "Cl" represents chlorine. The symbols in the brackets show the physical state of the substance, (g) is gaseous, (s) is solid, (aq) is aqueous and (l) is liquid.

The diagram below shows different layers of sedimentary rocks.Picture showing seven layers of rocks of different colors labeled A, B, C, D, E, F, and G from top to bottom; A and B are parallel horizontal layers at the top of the diagram and C, D, E, F, and G are slanted layers with C closest to the surface and G at the bottom.

Based on the diagram, which of these inferences is most likely correct?

A.Layer A is older than Layer B.
B.Layer C is older than Layer E.
C.Layer F is younger than Layer D.
D.Layer B is younger than Layer G.

Answers

Picture showing seven layers of rocks of different colors labeled A, B, C, D, E, F, and G from top to bottom;
A and B are parallel horizontal layers at the top of the diagram;
C, D, E, F, and G are slanted layers with C closest to the surface and G at the bottom.

The inference that is most likely correct is that (C) Layer F is younger than Layer D.

How is the number of valence electrons related to the ionization energy of an element?A) low ionization energy correlates to elements with fewer valence electrons
B) elements with higher ionization energy tend to have less valence electrons
C) atoms with nearly full valence electrons shells have lowers ionization energy
D) high ionization energy indicated a low likelihood to gain valence electrons

Answers

The number of valence electrons is related to the ionization energy of an element such that when there is few valence electrons, the ionization energy of an element is lower. The trend on the periodic table follows that the ionization energy fairly increases as the number of valence electron increases. Therefore the correct answer is letter "A."
