Question 2 Draw The Major Product Of The Elimination Reaction Shown.
Answers
An elimination reaction can have two products major and minor which are shown in the attached diagram below.
What is an elimination reaction?An elimination reaction can be described as a type of organic reaction in which two substituents are eliminated from a molecule in either a one- or two-step mechanism.
The one-step mechanism is called the E₂ reaction, and the two-step mechanism is called the E₁ reaction. The kinetics of the reaction: E₂ is bimolecular or second-order while E₁ is a unimolecular or first-order reaction.
In cases where the molecule is capable to stabilize an anion but has a poor leaving group, a third type of reaction, E₁-CB.
The E₂ mechanism involves a one-step mechanism in which carbon-hydrogen and carbon-halogen bonds break to prepare a double bond.
E₁ stands for unimolecular elimination where the carbon-halogen bond breaks to give a carbocation intermediate and then deprotonation of the carbocation.

What does a positive H look like on a potential energy diagram?
Answers
Answer:
D because i did this last week and got it right.
A positive H indicates that the potential energy of products is higher than the potential energy of reactants.
What is a potential energy diagram?A potential energy diagram is a diagram which shows the energy content of reactants and products as well as the energy changes that occur in a reaction.
A positive H in a reaction indicates that the reaction is endothermic and that products have a higher potential energy than reactants.
Therefore, a positive H indicates that tje potential energy of products is higher than the potential energy of reactants.

in an electroplating apparatus, where does the oxidation reaction occur?
a. on the surface of the battery
b. on the surface of the cathode
c. in the solution
d. on the surface of the anode
Answers
Answer:
I believe it’s on the surface of the anode!
Explanation:
Electroplating apparatuses are the devices used in the electroplating of metals. The oxidation reaction occurs on the anode of the plate. Thus, option d is correct.
What is oxidation?Oxidation is the process of the redox reaction in which the atoms or the ions lose their electron to the positive anode. The negative of the ionic species gets attracted to the positive of the anode.
The negative ions act as charges deposited on the positively charged anode and conduct electric current. The oxidation of the species will always occur at the anode of the electrochemical cell.
Therefore, option d. oxidation occurs at the surface of the anode.

How does the rate of a chemical reaction change if the concentration of both reactants increases 4 times?
2NO + O2 → 2 NO2
Answers
Answer: The rate will increase 32 times if the concentration of both reactants increases 4 times
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
For the reaction : [tex]2NO+O_2\rightarrow 2NO_2[/tex] [tex]rate=k[NO]^2[O_2]^1[/tex]
k= rate constant
order with respect to [tex]NO_2[/tex] = 2
order with respect to [tex]O_2[/tex] = 1
Thus on increasing the concentration of reactants 4 times :
[tex]rate'=k[4\times NO]^2[4\times O_2]^1[/tex]
[tex]rate'=k\times 8\times 4\times [NO]^2\times [O_2]^1[/tex]
[tex]rate'=32\times rate[/tex]
Thus rate will increase 32 times if the concentration of both reactants increases 4 times

D. Sunspots have lower temperatures than their surroundings
Explanation:
Sunspots is a phenomenon that involves temporary appearance of dark areas on the Sun's surface, which are regions of concentrated magnetic field flux which inhibit heat transfer by convection and are therefore cooler than other parts of the Sun. Due to the presence of magnetic field magnetic
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Opposite magnetic polarity sunspots usually appear as a pair.
Therefore, the statement that best describe sunspots is that a sunspot is a region of reduced temperature compared to surrounding areas on the Sun's surface.
Si Hecho Dos Cubos de Hielo En Un Vaso Con Agua Señalo Donde Quedo El Nivel Del Agua, Luego A Pasar El Tiempo Dejo Que Se Derritan Los Cubos De Hielo El Nivel Del Agua Aumenta??
Answers
Answer:
Ver explicacion
Explanation:
Técnicamente, cuando el hielo se derrite, ocupa aproximadamente el mismo volumen de agua que es igual a la masa de agua desplazada antes de que el hielo se derrita. Esto es posible solo cuando se ignora el cambio en la densidad del agua.
Sin embargo, si tenemos en cuenta el ligero cambio en la densidad del agua, se puede demostrar que el volumen de hielo es mayor que el del agua líquida porque el agua se expande cuando se congela.
Esto significa que el volumen de agua disminuye cuando el hielo se derrite.

What volume, in liters, of 0.500 M HNO3 is necessary to react with 25.0 mL of 0.0500 M Ca(OH)2 solution to the endpoint? HNO3 + Ca(OH)2. --> Ca(NO3)2 + H2O
Answers
Answer:
0.00500L are necessaries
Explanation:
Based on the balanced chemical reaction:
2HNO3 + Ca(OH)2. --> Ca(NO3)2 + 2H2O
2 moles of nitric acid react with 1 mole of calcium hydroxide
To solve this question we must find the moles of Ca(OH)2. Then, convert this moles to moles of HNO3 using the chemical reaction and to liters:
Moles Ca(OH)2:
0.025L * (0.0500mol / L) = 0.00125 moles Ca(OH)2
Moles HNO3:
0.00125 moles Ca(OH)2 * (2 moles HNO3 / 1mol Ca(OH)2) = 0.0025 moles HNO3
Liters HNO3:
0.0025 moles HNO3 * (1L / 0.500moles) = 0.00500L are necessaries

A student weighs an empty flask and stopper and finds the mass to be 53.256 g. She then adds about 5 mL of an unknown liquid and heats the flask in a boiling water bath at 98.8°C. After all the liquid is vaporized, she removes the flask from the bath, stoppers it, and lets it cool. After it is cool, she momen- tarily removes the stopper, then replaces it and weighs the flask and condensed vapor, obtaining a mass of 53.780 g. The volume of the flask is known to be 231.1 mL. The absolute atmospheric pressure in the laboratory that day is 728 mm Hg. a. What was the pressure of the vapor in the flask in atm?
Answers
Answer:
a. The pressure in the flask open to the atmosphere during the vaporization of the unknown liquid is equal to the prevailing atmospheric pressure equivalent to 0.957734 atm
Explanation:
The mass of the empty flask and stopper, m = 53.256 g
The volume of the unknown liquid she adds = 5 mL
The temperature of the water in which she heats up the flask = 98.8 °C = 371.95 K
The mass of the flask and the condensed vapor = 53.780 g
The volume of the flask, V = 231.1 mL
The atmospheric pressure, P = 728 mm Hg
a. We note that the student stoppers the flask after all the liquid has evaporated. Therefore, given that the flask was open to the atmospheric pressure as the liquid evaporates, the pressure of the vapor in the flask is equal to the prevailing atmospheric pressure, or 728 mmHg
Using a calculator, 728 mm Hg is equivalent to 0.957734 atm.
