what is the molecular formula if the emperical formula C2H5 and the molcuar molar mass is 58.14 g/mol0

Ivanshal [37]

Answer:

C4H10

Explanation:

Remark

Every periodic table is different. I'm going to use approximate numbers.

Emperical Formula Mass

2C = 2 * 12 = 24

H5 = 5 1 5

Emperical Formula Mass = 29

Solution

To get the molecular Molar Mass, you use

Molecular Molar Mass = number of mol of each constituent * empirical molar mass

Molecular mass = 58.14 rounded to 58

empirical mass = 29

moles = constitutent = ?

58 = 29 * mols constituent Divide by 29

2 = moles constituent

Answer

(C2H5)_2

C4H10

Cyclohexane (C6H12) undergoes a molecular rearrangement in the presence of AlCl3 to form methylcyclopentane (CH3C5H9) according

serious [3.7K]

Answer:

The reaction will shift leftwards, towards the formation of more cyclohexane at 25 °C

Explanation:

Hello,

In this case, for the given chemical reaction, we can write the law of mass action (equilibrium expression) as shown below:

$Kc=\frac{[CH_3C_5H_9]}{[C_6H_{12} ]}$

Thus, since Kc < 1, we can conclude there are more moles of cyclohexane at equilibrium (denominator is greater than numerator), therefore, the reaction will shift leftwards, towards the formation of more cyclohexane at 25 °C.

Best regards.

You dissolve NH&CN in water. Will the resulting solution be acidic or basic? You need to explain your answer using the appro

Advocard [28]

NH₄CN is a salt formed from weak base NH₄OH and weak acid HCN so that it undergoes complete hydrolysis

<h3>Further explanation</h3>

The hydrolysis process is a term used for the reaction of substances with water

There are 3 types of hydrolysis salts

1.Salt from strong acids and strong bases does not undergo hydrolysis so that the pH of the neutral solution = 7

2.Salt from strong acids and weak bases (pH <7) or from strong bases and weak acids (pH> 7) will be partially / partially hydrolyzed

3.Salt from weak acids and weak bases (pH depends on the value of Ka and Kb) will be completely hydrolyzed

NH₄CN is a salt formed from weak base NH₄OH and weak acid HCN so that it undergoes complete hydrolysis

NH₄OH + HCN⇒NH₄CN+H₂O

Can be formulated :

$\tt [H^+]=\sqrt{\dfrac{Kw\times Ka}{Kb} }$

Ka> Kb then [H +]> 7 and pH <7 ⇒ acidic

Ka <Kb then [H +] <7 or pH> 7 ⇒alkaline

Ka = Kb then pH = 7 ⇒neutral

What do the two tails of a comet consist of ?

djyliett [7]

There are two types of comet tails: dust and gas ion. A dust tail contains small, solid particles that are about the same size found in cigarette smoke. This tail forms because sunlight pushes on these small particles, gently shoving them away from the comet's nucleus.
