One method for preparing a nitrile is the dehydration of a primary amide.

1 answer:

4 0

True because a dehydration reaction is a conversion that involves the loss of water from the reacting molecule or ion. Dehydration reactions are common processes, the reverse of a hydration reaction. Common dehydrating agents used in organic synthesis include sulfuric acid and alumina. Often dehydration reactions are effected with heating.

The quantity (current times voltage ) is

maksim [4K]

Answer:

Electrical power

Explanation:

An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.

Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, etc.

The electrical power of an electric circuit can be defined as a measure of the rate at which energy is either produced or absorbed in the circuit.

Mathematically, electrical power is given by the formula;

$Electrical \; power = current * voltage$

This ultimately implies that, the quantity (current times voltage ) is electrical power and it is measured (S.I units) in Watt (W).

The equilibrium constant is given for two of the reactions below. Determine the value of the missing equilibrium constant. A(g)

wolverine [178]

Answer:

The correct answer is 8.10

Explanation:

Given:

A(g) + 2B(g) ↔ AB₂(g) Kc = 59 ---- Eq. 1

A(g) + 3B(g) ↔ AB₃(g) Kc = 478 ----- Eq. 2

We have to rearrange the chemical equations in order to obtain:

AB₂(g) + B(g) ↔ AB₃(g) Kc = ?

AB₂(g) is a reactant, so we have to use the reverse reaction of Eq. 1, in this case Kc= 1/59. Since AB₃(g) is a product, we use the forward reaction of Eq.2, and the constant is the same: Kc= 478. The following is the sum of rearranged chemical equations, and the compounds in bold and italic are canceled:

AB₂(g) ↔ A(g) + 2B(g) Kc₁= 1/59

A(g) + 3B(g) ↔ AB₃(g) Kc₂= 478

-----------------------------------------

AB₂(g) + B(g) ↔ AB₃(g)

If we add reactions at equilibrium, the equilibrium constants Kc are mutiplied as follows:

Kc = Kc₁ x Kc₂ = 1/59 x 478 = 478/59 = 8.10

The value of the missing equilibrium constant is 8.10.

Why is the circulatory system so important? please explain in own yours I keep getting copy and paste please don’t do that it’s

expeople1 [14]

Importance of Circulatory System

This system helps in transportation of respiratory gases like O2 and CO2, nutrients, hormones, enzymes, minerals, waste products.
It helps in storage of essential substances for future use.
It also generates heat to the body.

Hope you could understand.

If you have any query, feel free to ask.
