Answer:I did not understand the question nicely by from whatever i understand the answer is yes
Explanation:
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
They are different elements. However, most of their chemical properties are similar, because of the similar numbers of electrons in their valence shells. Their physical properties differ because of the mass contained in the atoms of <span>each element.</span>
Answer:
a) Qc = 0.6338
b) Qc < Kc ⇒ the reaction proceeds to the right, towards the products.
Explanation:
∴ Kc = 9.8 E5 = [H2S] / [H2]
a) reaction quotient, Q:
∴ Qc = [H2S] / [H2] = (0.483 M)/(0.762 M) = 0.6338
b) the process is not established equilibrium: Qc < Kc
⇒ The reaction evolves to the right, towards the products
Answer:
for the given reaction is -2486.3 kJ
Explanation:
The given equation can be written as a combination of the following equation:

The concentration of the HCL in the mixed solution is 32%
Considering the First solution containing HCl,
80 ml of 50% = 80 x (50/100)
= 80 x 0.5
= 40 ml of HCL
Considering the second solution containing HCl,
120 ml of 80% = 120 x (20/100)
= 120 x 0.2
= 24 ml of HCl
So, the combined solution will have = 40+ 24
= 64 ml of HCL
Since the combined volume of the two solutions was = 80+120
= 200 ml
As for finding the concentration of HCl in a solution, the required formula is to divide the volume of HCl by the combined volution of the solution.
Therefore, the concentration of HCl will be = 64/200
= 0.32
Which is 32% of HCl
