Hello!

For solving this problem we first have to determine the pKa of CH₃COOH.

pKa=-log(Ka)=-log( 1,80*10^{-5} )=4,74

Now, we use the Henderson-Hasselbach's equation to determine the pH of the buffer solution:

pH=pKa+log (\frac{NaCH_3COO}{CH_3COOH} )=4,74+log( \frac{0,050M}{0,075M} )=4,56

So, the pH of this solution is 4,56

Have a nice day!

acid-catalyzed hydration of 1-methylcyclohexene gives two alcohols. The major product does not undergo oxidation, while the mino
noname [10]

Answer:

Major product does not undergo oxidation since it is a tertiary alcohol whereas minor product undergoes oxidation to ketone as it is  secondary alcohol.

Explanation:

Hello,

In this case, given the attached picture, the hydration of the 1 methylcyclohexene yields to alcohols; 1-methylcyclohexan-1-ol and 1-methylcyclohexan-2-ol. Thus, since the OH in the 1-methylcyclohexan-1-ol (major product) is bonded to a tertiary carbon (bonded with other three carbon atoms) it is not able to increase the number of oxygen bonds (oxidation) as it already attained the octet whereas the 1-methylcyclohexan-2-ol (minor product) is able to undergo oxidation to ketone as the carbon bonded to it is secondary (bonded with other two carbon atoms), so one extra bond the oxygen is allowed to be formed to carbonyl.

Best regards.

Compare and contrast physical layers and compositional layers.
Yuki888 [10]

Answer:

Compositional Layers

The Earth has different compositional and mechanical layers. Compositional layers are determined by their components, while mechanical layers are determined by their physical properties. The outermost solid layer of a rocky planet or natural satellite.

Given the unbalanced equation: N2(g) + H2(g) → NH3(g)
mario62 [17]

Answer:

                   Option-4 (3:2) is the correct answer.

Explanation:

Following steps are taken to balance the given unbalanced chemical equation.

Step 1: Write the unbalanced chemical equation,

                         N₂ +  H₂ →  NH₃

Step 2: Balance Nitrogen Atoms;

There are 2 nitrogen atoms on left hand side and 1 nitrogen atoms on right hand site therefore, to balance them multiply NH₃ on right hand side by 2 i.e.

                         N₂ +  H₂ →  2 NH₃

Step 3: Balance Hydrogen Atoms;

Now, there are 2 hydrogen atoms on left hand side and 6 hydrogen atom on right hand site therefore, to balance them multiply H₂ on left hand side by 3 i.e.

                         N₂ +  3 H₂ →  2 NH₃

Now, the equation is balanced.

Step 4: Finding out mole ratios:

From balanced chemical equation it can be concluded that 3 moles of H₂ are involved in producing 2 moles of NH₃ hence, the mole ratio of consumption of H₂ to production of NH₃ is 3:2.

Identify which substitution product is expected to be favored. Explain. The inverted product is expected to predominate slightly
egoroff_w [7]

The substitution product that is suppose to be favoured is The product with retention of configuration is expected to predominate slightly, because the leaving group blocks the nucleophile.

<h3>What is substitution product?</h3>

Substitution product is a product that is gotten from a reaction in which a group of reactant is replaced by another group in the reaction.

Therefore,The substitution product that is suppose to be favoured is The product with retention of configuration is expected to predominate slightly, because the leaving group blocks the nucleophile.
