bulgar [2K]

Answer:

Few important points related to S_N2 reaction:

1. S_N2 is a one-step reaction that follows second order kinetics.

2. In S_N2 reaction, a transition state is formed in situ.

3. Strong nucleophiles like OH^- \ or\  CN^- are used in case of bi-molecular nucleophilic substitution reaction.

Ethyl acetate can be prepared by a second-order nucleophilic substitution reaction between acetic acid and ethyl bromide.  

The reaction between acetic acid and ethyl bromide is drawn below:

In which of the following pure substances would hydrogen bonding be expected?
Novay_Z [31]

Answer:propanoic acid

Explanation:

Carboxylic acids contain the COOH group. This group is capable of hydrogen bonding leading to association of the molecules. Cyclobutane is a cyclic alkane and acetone is a ketone. Non of these compounds posses a polar -OH bond which is necessary for the occurrence of hydrogen bond. Hydrogen bonds only occur in carboxylic acids and alcohols. Hydrogen bond leads to molecular association and high boiling points.

What amount of heat energy is required to raise the temperature of 152 g of water from 24 °C to 74 °C.
DIA [1.3K]

Answer:

Q = 31798.4J = 31.79kJ

Explanation:

Heat energy (Q) = ?

Mass (m) = 152g

T1 = 24°C

T2 = 74°C

Specific heat capacity of water (c) = 4.184J/g°C

Q = Mc∇T

Q = 152 * 4.184 * (74 - 24)

Q = 635.968 * 50

Q = 31798.4J

Q = 31.79kJ

Heat required is 31.79kJ

Calculate the volume(in L), at STP, of carbon dioxide produced by the complete combustion of 6.75 lbs of charcoal.
gtnhenbr [62]

535.8 L volume(in L), at STP, of carbon dioxide produced by the complete combustion of 6.75 lbs of charcoal.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Given:

C(s) + O_2(g) ⇒CO_2(g)

1 mole of CO_2(g) is formed from 1 mole of charcoal, that means 1 mole of CO_2(g) is formed from 12 g of charcoal.

1 lbs = 453.592 grams

6.75 lbs = 6.75 x 453.592 =3061.746g

So, CO_2(g) formed from 3061.746g of charcoal is:

=\frac{1}{12} x 3061.746g

=255.14 mol.

Now, at STP, the volume of 1 mol of gas =22.4 L

Volume of 255.14 mol of CO_2(g) = 255.14 x 22.4 L

Volume of 255.14 mol of CO_2(g) = 535.8 L

Hence, 535.8 L volume(in L), at STP, of carbon dioxide produced by the complete combustion of 6.75 lbs of charcoal.
