Answers

The rearrangement produces a more stable tertiary carbocation and the unexpected product.

In the image shown, the substrate is 1-cyclobutylethene. The attack of H2SO4 and water will lead to the conversion of the alkene to an alkanol. Two possible products may be obtained with one being greater than the other.

The unexpected product (Shown in the image attached) is obtained due to rearrangement of the carbocation intermediate. The rearrangement produces a more stable tertiary carbocation and the unexpected product.

What volume of 0.205 MK2S solution is required to completely react with 185 mL of 0.120 MCo(NO3)2?

Answers

Answer:

the balanced equation for the above reaction is as follows;

3NiCl₂ + 2K₃PO₄ ---> Ni₃(PO₄)₂ + 6KCl

stoichiometry of NiCl₂ to K₃PO₄ is 3:2

the number of NiCl₂ moles reacted - 0.0102 mol/L x 0.134 L = 0.00137 mol

according to molar ratio  

if 3 mol of NiCl₂ reacts with 2 mol of K₃PO₄

then 0.00137 mol of NiCl₂ reacts with - 2/3 x 0.00137 = 0.000911 mol of K₃PO₄

molarity of given K₃PO₄ solution - 0.205 M

there are 0.205 mol in 1000 mL  

therefore volume of 0.000911 mol - 0.000911 mol / 0.205 mol/L = 4.44 mL  

volume of K₃PO₄ needed is 4.44 mL

Determine the rate of reaction at 50 C when the loss of mass is 0.95 g. Show your working. Give your answer to 2 significant figures.

* 20 points for who gets it *

Answers

This problem is providing information about the loss of mass for a reaction 50 °C as a function of the time elapse. Thus, when taking a look at the given graph, we can trace a horizontal line on the y-axis at 0.95 g in order to intercept it with the curve, and hence, figure out the time at which that loss of mass takes place.

Thus, we can see that when the loss of mass hits 0.95 g, the corresponding time on the graph is about 80 seconds, and hence, the rate of reaction turns out to be:

[tex]r=\frac{0.95g}{80s}\\\\r=0.012\frac{g}{s}[/tex]

why are there no elementary substances that have the ionic bond?

Answers

This problem is asking for the reason behind the nonexistence of elementary substances with ionic bonds. First of all, it is necessary to bear to mind that the definition of the type of bond in a compound depends on the difference electronegativity that is present between two of the atoms composing it.

For instance, in binary salts, such as KCl, NaCl, KBr and so on, we are able to know these are all ionic because they are composed by a metal and a nonmetal, which have the smallest and largest electronegativities, so that the difference electronegativity is large enough to produce an ionic bond.

In contrast, elementary susbtances, such as liquid bromine (Br2) and gases such as H2, N2, Cl2, F2 and O2, since they are all nonmetals and the same type, the electronegativity difference will be 0 and therefore, they will not be ionic but covalent.

How much aluminum can be extracted from 3.5 metric tons of bauxite ore which is 70% aluminum oxide?

Answers

Answer:

A) 17.5%

B) 1) 2135 kg

2) 375 kg

C) 91.8

Explanation:

Part (A):

1 tonne= 1000 kg= 100%

Aluminium oxide= 825 kg= 82.5%

Iron (lll) oxide= 100 kg= 10%

Sand= 85 kg= 7.5%

That makes total of 100%

So, the percentage of impurities= Iron (lll) oxide + Sand

=> 10 + 7.5= 17.5%

Part (B):

(1) 1 tonne= 427 kg

Multiplying both sides by 5

=> 5 tonne= 427 * 5

=> 5 tonne = 2135 kg

(2) 1 tonne contains 75 kg sand as impurity

=> 1 tonne= 75 kg

Multiplying both sides by 5

=> 5 tonnes = 75 * 5

=> 5 tonnes = 375 kg

Part (C):

If all of the iron oxide was removed, then only aluminium and sand are left.

Aluminium = 825 kg

Sand= 74 kg

Total of them makes it:

=> 825 + 74 = 899

So,

% age of Aluminium= 825/899 * 100

% age of Aluminium= 0.918 * 100%

% age of Aluminium= 91.8%
