Question 1
Nastasia [14]

In the given compound, 0.2 mole of C₂H₆O will contain 1.2 moles of hydrogen.

<h3>chemical compound</h3>

In the balanced chemical compound C₂H₆O, we can deduce the following;

1 mole of C₂H₆O contains 6 moles of hydrogen

0.2 mole of C₂H₆O = ?

= 0.2 x 6 moles = 1.2 moles of hydrogen

Thus, in the given compound, 0.2 mole of C₂H₆O will contain 1.2 moles of hydrogen.

Need help with chemistry question
luda_lava [24]

Answer:

See explanation

Explanation:

In this case, we have to check two variables:

1) The leaving group

2) The carbon bonded to the leaving group.

Let's check one by one:

<u>2-chloro-3-methylbutane</u>

<u />

In this molecule, the leaving group is "Cl", the carbon bonded to the leaving group has two neighbors. Therefore, we have a <u>secondary substrate.</u>

<u>1-phenylpropan-1-ol</u>

<u />

In this molecule, the leaving group is "OH", the carbon bonded to the hydroxyl group has two neighbors also. So, we have a <u>secondary substrate.</u>

<u>(E)-pent-3-en-2-yl 4-methylbenzenesulfonate</u>

<u />

In this case, the leaving group is "OTs" (Tosylate), the carbon bonded to the tosylate group has as a neighbor a double bond. Therefore, we have an <u>allylic substrate.</u>

<u>3a-bromooctahydro-1H-indene</u>

<u />

In this molecule, the leaving group is "Br", the carbon bonded to the bromine has three neighbors. So, we have a <u>tertiary substrate.</u>

<u>1-iodo-3-methylbutane</u>

<u />

In this molecule, the leaving group is "I", the carbon bonded to the iodide has only one neighbor. So, we have a <u>primary substrate.</u>

<u />

See figure 1

I hope it helps!

Consider the reaction H2(g) I2(g) Double headed arrow. 2HI(g). What is the reaction quotient, Q, for this system when [H2] = 0.
Dima020 [189]

The reaction for the formation of HI, at the given time, has a reaction quotient of 613.

What is the reaction quotient?

Reaction quotient is the ratio of the concentration of product and reactant raised to the stoichiometric power at a given time interval.

The chemical reaction for the formation of HI is given as:

\rm H_2\;+\;I_2\;\rightarrow\;2\;HI

The reaction quotient is given as:

\rm Q=\dfrac{[HI]^2}{[H_2]\;[I_2]}

The concentration of system at the time, t has been:

Hydrogen = 0.1 M

Iodine = 0.2 M

HI = 3.5 M

Substituting the values for reaction quotient:

\rm Q=\dfrac{(3.5)^2}{(0.1)(0.2)}\\ Q=613

The reaction quotient for the reaction is 613. Thus, option D is correct.
