Answer:
This question is incomplete
Explanation:
This question is incomplete as the volume of the base that was used during the titration was not provided. However, the completed question is in the attachment below.
The formula to be used here is CₐVₐ/CbVb = nₐ/nb
where Cₐ is the concentration of the acid = unknown
Vₐ is the volume of the acid used = 25 cm³ (as seen in the question)
Cb is the concentration of the base = 0.105 mol/dm³ (as seen in the question)
Vb is the volume of the base = 22.13 cm³ (22.1 + 22.15 + 22.15/3)
nₐ is the number of moles of acid = 1 (from the chemical equation)
nb is the number of moles of base = 2 (from the chemical equation)
Note that the Vb was based on the concordant results (values within the range of 0.1 cm³ of each other on the table) of the student
Cₐ x 25/0.105 x 22.13 = 1/2
Cₐ x 25 x 2 = 0.105 x 22.13 x 1
Cₐ x 50 = 0.105 x 22.13
Cₐ = 0.105 x 22.13/50
Cₐ = 0.047 mol/dm³
The concentration of the sulfuric acid is 0.047 mol/dm³
Don't all halogens have 8 valence electrons? They don't need to gain or lose any because they are already stable.
Answer:
Biochemistry is the discipline that studies the chemistry of life, and its objective is to explain form and function based on chemical principles. Organic chemistry is the discipline devoted to the study of carbon-based chemistry, which is the foundation for the study of biomolecules and the discipline of biochemistry. Both biochemistry and organic chemistry are based on the concepts of general chemistry, some of which are presented in Fundamentals of Physics and Chemistry Important to Microbiology.

Answer:
Organizing a Birthday Party
On 20 June I was born and every year me and my parents celebrate my birthday in our house. But, This time I had an idea to organize my birthday party in a Big Hall where all my classmates and society friends will join me and we'll play lots of games and Have an amazing party.
So, I discussed my this idea with my father and he said "Okay, we'll celebrate your birthday this time as you wish". Then I took help from my GrandPa to send out invitation cards to my friend's and my father was going to book a Big Party Hall in 'The Calves Restaurant' where we will celebrate my birthday and my mother helped me in getting game ideas which we will play on the birthday.
On Birthday (20th June), when everybody arrived one of my friend sang a beautiful Birthday song from me. Then I blew out the candles off the cake. We also had games like Ludo, carrom, passing pillow, musical chair, and etc. At the end we had DJ where all my friends and my family members enjoyed. This was an amazing party to everyone.
