Answer:
8.76M
Explanation:
Given that
Mass from the density = 1141g
According to the given situation the computation of molarity of the solution is shown below:-
we will took HCL solution which is 1000mL
HCl = 28% by mass
So,
Mass of HCl in 1-litre solution is
Which gives the result of molar mass HCI is
= 319.48g /mol
Now,
Molarity is
Which gives results of molarity is
= 8.76M
Explanation:
Contributing structures are the resonating structures which are formed due to the delocalization of electrons in a molecule.
The azide ion that is , is a symmetrical ion, all of whose contributing structures have formal charges.
Lone pair of central nitrogen atom in azide ion is in conjugation with the neighboring nitrogen atoms.
Contributing structures of azide ion are drawn in the image attached.
Answer:
<h2>The answer is 35 mL</h2>Explanation:
Density of a substance can be found by using the formula
From the question we are finding the amount of space the gas will occupy that's the volume of the gas
Making volume the subject we have
From the question
mass = 23.8 g/mL
Density = 0.68 g/mL
Substitute the values into the above formula and solve
That's
We have the final answer as
<h3>35 mL</h3>Hope this helps you
Explanation:
Le Chatelier's principle states that for a long period of time if a system is at equilibrium and it is subjected to change in concentration, temperature, volume or pressure then the system shifts to a new equilibrium.
This change will partly counter acts the applied change.
Therefore, when heat is added to the system then equilibrium will shift to the side where temperature or heat is reduced again.
For example,
Since heat is added to the system, hence, system will shift to the left side or we can say equilibrium will shift to the backward direction.
