Answer:

Answer: The formula of the hydrate is [tex]MnSO_4.2H_2O[/tex]

Explanation:

Decomposition of hydrated manganese sulphate is given by:

[tex]MnSO_4.xH_2O\rightarrow MnSO_4+xH_2O[/tex]

Molar mass of [tex]MnSO_4[/tex] = 151.0 g/mol

According to stoichiometry:

(151.0+18x) g of [tex]MnSO_4.xH_2O[/tex] decomposes to give 151.0 g of [tex]MnSO_4[/tex]

Thus 45.91 g of [tex]MnSO_4.xH_2O[/tex] decomposes to give= [tex]\frac{ 151.0}{151.0+18x}\times 45.91g[/tex]  of [tex]MnSO_4[/tex]

Also we are given : 37.07 g of  [tex]MnSO_4[/tex] is produced

Thus we can equate the two equations:

[tex]\frac{ 151.0}{151.0+18x}\times 45.91=37.07[/tex]

[tex]x=2[/tex]  

Thus the formula of the hydrate is [tex]MnSO_4.2H_2O[/tex]

Answer:

0.1795 M

Explanation:

From the given information:

The equation is:

[tex]\mathbf{HF_{(aq)}+ KOH_{(aq)} \to KF _{(aq)} + H_2O}[/tex]

From the above equation, the reaction will go to completion due to the strong base:

At the equivalence point, moles of acid (HF) will be equal to moles of base (KOH)

[tex]\text{Number of moles = Volume} \times Molarity[/tex]

Thus. since moles of HF = moles of KOH

Then; 0.020 × 0.393 M = 0.02379 × (x) M

(x) M = [tex]\dfrac{0.02 \times 0.393 \ M}{0.02379}[/tex]

(x) = 0.3304 M

Thus, the molarity of KOH = 0.3304 M

Using the balanced neutralization reaction;

moles of HF = moles of KOH = moles of conjugate base = 0.00786 mol

∴

Volume = 0.020 L + 0.02379 L

Volume = 0.04379 L

Volume of the solution =  0.04379 L

Therefore; Molarity = [tex]\dfrac{moles}{volume}[/tex]

Molarity = [tex]\dfrac{0.00786 \ mol}{0.04379 \ L}[/tex]

Molarity = 0.17949 mol/L

= 0.1795 M

After the initial neutralization, the molarity at the equivalence point will be:

"0.17949 mol/L"

According to the question,

→ HF (aq) + KOH (aq) [tex]\rightarrow[/tex] KF (aq) + H₂O

Since, moles of HF = moles of KOH

We know that,

Number of moles = Volume × Molarity

→ 0.020 × 0.393 = 0.02379 × M

By applying cross-multiplication,

The molarity of KOH be:

M = [tex]\frac{0.02\times 0.393}{0.02379}[/tex]

   = [tex]\frac{0.00786}{0.02379}[/tex]

   = 0.3304 M

By using balanced neutralization reaction,

Volume = 0.020 + 0.02379

             = 0.04379 L

hence,

The molarity will be:

= [tex]\frac{Moles}{Volume}[/tex]

By substituting the values,

= [tex]\frac{0.00786}{0.04379}[/tex]

= 0.17949 mol/L

Thus the response above is correct.

Explanation:

The synthesis of asprin involves the;

i) Hydrolysis of Methyl salicylate

ii) Reaction of salicylic acid with acid anhydride

The chemical name of asprin is acetylsalicylic acid.

It is preferable to use an acid anhydride for ester formation with an alcohol rather than a carboxylic acid because we will not produce water which can then cause the hydrolysis of the newly formed ester.

While many public hotspots offer free wireless access on an open network, others require payment.

A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.

Answer:

The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral.

Answer:

b is ur answer

Explanation:

1S and 4O

Answer:

Explanation:

The standard molar mass is:

For (S )-1-chloro-4-ethyl-2-methylhexane = 162.5 g/mol

For triphenylphosphine  = 262 g/mol

For  ( S )-1-chloro-4-ethyl-2-methyl triphenylphosphonium = 424.5 g/mol

The mass required for 81% yield = [tex]\dfrac{81}{100} \times Theoretical \ yield = 4.15 g[/tex]

Theoretical yield = [tex]\dfrac{4.15}{0.81}[/tex]

= 5.1235 g

thus, since 424.5 g yield produce from 162.5 g

∴

5.1235 g yield will produce = [tex]\dfrac{162.5}{424.5}\times 5.1235 \ g[/tex]

= 1.9613 g of alkyl halide (-chloro) required.

Also, since 424.5 g yield produce from 262 g phosphine

∴

5.1235 g yield will produce = [tex]\dfrac{262}{424.5}\times 5.1235 \ g[/tex]

= 3.1622 g of triphenylphosphine required.

The volume 15.0 g of O₂ has at a certain temperature and pressure is 2.16 L.

Volume is the space occupied by a three-dimensional object.

By the law of dilution

M₁/V₁ = M₂/V₂

Mass 1 is 5.00

Volume 1 is 7.20 L

Mass 2 15.0 g

Volume 2 is to find

Putting the value in the equation

5.00/ 7.20 = 15.0 / V₂

V₂ = 7.20 × 15.00/ 5.00 = 21.6

Thus, the volume will be 21.6 L.

https://brainly.com/question/1578538

Answer:

Explanation:

No, it is ludicrous and not possible to separate and detach a basic and neutral compound by 1M NaOH in DCM. This is due to the fact that neutral compounds don't respond and react with NaOH, and NaOH itself occurs to be a base. As a result, it can't respond and react with another base to produce salt. Consequently, we simply need a corrosive component i.e an acid

So; In DCM, we can't use 1M NaOH instead of 1M HCI for isolation and separation of neutral and basic compound mixtures.
