Answer: <span>The main interactions between molecules of hydrogen chloride are examples of
Dipole-Dipole Interactions.
Explanation: The bond between Hydrogen and Chlorine is
Polar Covalent Bond as the
electronegativity difference between these two elements is
0.96 which is greater than 0.4. Chlorine being more electronegative attracts the electrons from Hydrogen making the Hydrogen
partial positive and itself
partial negative. The two poles on HCl makes it a dipole. Now, one HCl (a dipole) interacts with another HCl (another Dipole) through their opposite charges and creates
Dipole-Dipole Interaction. The picture is as below, the
green dashed lines are interactions,

Upon a constant pressure (P), volume (V) of a gas will vary in direct proportion to changes in temperature (T). So V1/T1 = V2/T2
V2 = V1T2/T1 = (500)(300)/150
V2 = 150000/150 = 1000 mL
Answer:
The answer is
<h2>57.52 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass of ice = 52.75 g
density = 0.917 g/cm³
The volume of the ice is

We have the final answer as
<h3>57.52 mL</h3>
Hope this helps you
Answer:
The temperature at which the reaction changes from non-spontaneous to spontaneous is 588.735 K
Explanation:
The spontaneity of a reaction is determined by the change in Gibbs Free Energy,
.

If
is greater than zero, then a reaction is feasible.
If
is less than zero, then a reaction is not feasible.
To determine the temperature at which the reaction changes from non-spontaneous to spontaneous, we should equate the
to zero.
We take
as the limiting condition.

Therefore, the temperature is: 588.735K
Answer:
D. 76%
Explanation:
Percent yield=actual/theoretical * 100
38/50 * 100 = 76%
