In general, when the addition of an unsymmetrical electrophilic reagent to an unsymmetrical alkene forms the product predicted by Markovnikov's rule, that occurs because: A) the product is statistically favored. B) steric hindrance favors its formation. C) it is formed via the more/most stable carbocation. D) it is the more/most stable product. E) All of these choices are reasons.

Answers

Answer 1

It is formed via the more/most stable carbocation.

What justification exists for Markovnikov's Rule?

A carbocation is created as a result of the protonation of the alkene by the protic acid. The carbocation that has the most alkyl substituents on its carbon holds the positive charge, making it the most stable carbocation. As a result, the addition of the halide to the carbon that has fewer hydrogen substituents makes up the majority of the product.

Markovnikov's rule

According to the Markovnikov rule, a proton is added to the carbon atom with the greatest number of hydrogen atoms connected in addition to processes involving alkenes or alkynes.

Anti-Markovnikov Rule

According to the Anti-Markovnikov Rule, in addition to reactions between alkenes or alkynes, The carbon atom with the fewest hydrogen atoms linked to it receives the proton.

A 21.5 g sample of nickel was treated with excess silver nitrate solution to produce silver metal and nickel(II) nitrate. The reaction was stopped before all the nickel reacted, and 36.5 g of solid metal (nickel and silver) is present. Calculate the mass of solid silver metal present in grams.

Answers

The mass of nickel is 36.5g metal.

Ni+2AgNO3 → Ni(NO3)2+2Ag

21.5g Ni / 58.69g = 0.366mol Ni

Ag = 107.87

N i= 58.69

But, 2molAg per 1 mol Ni, so, change in mass is more like...

Twice as many moles Ag as Ni, and then the mass relationship is 107.87g Ag / 58.69, but due to the 2Ag: 1Ni mol ratio, the change in mass is like:

107.87(2) / 58.69 = 3.68 times increase

So, the final mass of Ag is 3.68x, and the change in mass of Ni is x

36.5=(21.5-x)+(3.68x)

Solve for x

x=5.597

3.68x=g Ag

3.68(5.597)=20.59

21.5 - x = g Ni after reaction

21.5 - 5.597 = 15.903g Ni

20.59g Ag + 15.903g Ni = 36.5g metal

The mass of nickel is 36.5g metal.

Why are the two equilibrium reactions below not affected by an increase in pressure?

Answers

An increase in pressure does not affect the reaction because the moles of reactants and products or the pressure of the forward reaction are equal at equilibrium.

What is chemical equilibrium?

A chemical reaction is in equilibrium if the rate of the backward reaction and the forward reaction are equal.

Pressure affects the equilibrium position of chemical reactions involving gases.

For the given reactions in equilibrium, moles of reactants and products and hence, the pressure of the forward reaction are equal at equilibrium, therefore, an increase in pressure does not affect it.

Therefore, an increase in pressure will only affect the equilibrium of a reaction in which the pressure varies in the forward and backward reaction.

Answer: The concentration of the diluted solution is 1.566M.

Explanation:

The dilution equation is presented as this: [tex]M_{s} V_{s} =M_{d} V_{d}[/tex].

·M= molarity (labeled as M)

·V= volume (labeled as L)

·s= stock solution (what you started with)

·d= diluted solution (what you have after)

Now that we know what each part of the formula symbolizes, we can plug in our data.

[tex]11.6M*13.5mL=M_{d} *100mL[/tex]

We cannot leave it like this because the volumes must be in Liters, not milliliters. To convert this, we divide the milliliters by 1000.

[tex]13.5mL/1000=0.0135L[/tex]     [tex]100mL/1000=0.1L[/tex]

Now that we have the conversions, let's plug them into the equation.

[tex]M_{d} =\frac{11.6M*0.0135L}{0.1L}[/tex]       [tex]M_{d} =1.566M[/tex]

What would be the mass in grams of 0.300 moles of the ionic compound formed when magnesium metal reacts with oxygen

Answers

Answer:

Balanced Equation for reaction between Magnesium and Oxygen:

2Mg + O₂ --> 2MgO

Molar Mass of MgO is the atomic masses listed on the periodic table for the two elements Magnesium and Oxygen. Magnesium's molar mass is 24g/mol, and Oxygen's molar mass is 16g/mol. So MgO's molar mass would be 24 + 16 = 40g/mol.

The equation to find moles is:

[tex]moles \ = \ \frac{mass}{molar \ mass}[/tex]

So if we rearrange this equation to find for mass:

[tex]mass = moles \ * \ molar \ mass[/tex]

So you have to multiply 0.300 moles by 40, which gives you 12g

Meaning the mass of Magnesium Oxide is 12g.

How many grams of silver chromate will precipitate when 150. mL of 0.500 M silver nitrate are added to 100. mL of 0.400 M potassium chromate

Answers

The amount of silver chromate that precipitates after addition of solutions is 12.44 g.

Number of moles:

The number of moles is the product of molarity of the solution and its volume. The formula is expressed as:

Moles = Molarity x Volume

Calculations:

Step 1:

The molecular formula of silver nitrate is AgNO3. The number of moles of silver nitrate is calculated as:

Moles of AgNO3 = 0.500 M x (150/1000) L

= 0.075 mol

Step 2:

The molecular formula potassium chromate is K2CrO4. The number of moles of potassium chromate is calculated as:

Moles of K2CrO4 = 0.400 M x (100/1000) L

= 0.04 mol

Step 3:

The balanced chemical reaction between AgNO3 and K2CrO4 is:

2AgNO3 + K2CrO4 -----> Ag2CrO4 + 2KNO3

The required number of moles of K2CrO4 = 0.075 mol/2 = 0.0375 mol

The given number of moles of K2CrO4 (0.04 mol) is more than the required number of moles (0.0375 mol). Therefore, AgNO3 is the limiting reagent.

Step 4:

According to the reaction, the molar ratio between AgNO3 and Ag2CrO4 is 2:1. Hence, the number of moles of Ag2CrO4 formed is 0.0375 mol.

The molar mass of Ag2CrO4 is 331.74 g/mol.

The mass of Ag2CrO4 is calculated as:

Mass = 0.0375 mol x 331.74 g/mol

= 12.44 g

Answers

The half life is 0.47906yr

The uncertainty principle governs radioactive decay, making it impossible to predict with precision when a given nucleus will split apart and release a particle.

However, we can estimate the likelihood that a nucleus will dissolve in a specific amount of time.

We can foretell what portion of a huge number of nuclei will dissolve during that time.

Regardless of the isotope's quantity, this fraction will fluctuate based on each isotope's stability.

Alternatively, we can consider the issue in terms of how long it will take a specific fraction of an isotope to dissociate.

We have r0 = 6608 min–1 g–1, while r = 2932  min–1 g–1, and t = 7.29 days. Substituting into

we then have

ln r/r0 = −0.693*t / t1/2

ln (2932/6603) = -0.693 * 7.29 / t1/2

ln (0.44404) = -0.693*7.29/t1/2

t1/2 = (-0.693/-0.8118) * 7.29days

t1/2= 0.8536*7.29days

1yr = 28.1yrs

0.0199yr (7.29days)  = 0.56123yr
