Answer:
The pH of the solution will be 3
Explanation:
The strength of acids is determined by their ability to dissociate into ions in aqueous solution. A strong acid is any compound capable of completely and irreversibly releasing protons or hydrogen ions, H⁺. That is, an acid is said to be strong if it is fully dissociated into hydrogen ions and anions in solution.
Being pH=- log [H⁺] or pH= - log [H₃O⁺] and being a strong acid, all the HClO₃ dissociates:
HClO₄ + H₂O → H₃O⁺ + ClO₄-
So: [HCLO₄]= [H₃O⁺]
The molar concentration is:
The molar mass of HClO₄ being 100 g / mole, then if 100 grams of the compound are present in 1 mole, 0.025 grams in how many moles are present?
moles of HClO₄= 0.00025
Then:
![[HClO_{4}]=\frac{0.00025 moles}{0.25 L}](https://tex.z-dn.net/?f=%5BHClO_%7B4%7D%5D%3D%5Cfrac%7B0.00025%20moles%7D%7B0.25%20L%7D)
![[HClO_{4}]=0.001 \frac{ moles}{ L}](https://tex.z-dn.net/?f=%5BHClO_%7B4%7D%5D%3D0.001%20%5Cfrac%7B%20moles%7D%7B%20L%7D)
Being [HCLO₄]= [H₃O⁺]:
pH= - log 0.001
pH= 3

Answer:
Explanation:
The movement of the electrons is illustrated in the picture attached to this answer. It is a four-step reaction mechanism.
First STEP: The first step involves the transfer of an electron from sodium to form a radical anion.
Second STEP: This radical anion then removes a proton/hydrogen from ammonia in a bid to neutralize itself (hence the hydrogen becomes bonded to the anion).
Third STEP: The sodium (from NaNH₂ formed) transfers an electron again to produce a vinyl carbanion.
Fourth STEP: The carbanion then removes a proton/hydrogen from ammonia (like in the second step) to form a neutral trans-alkene.
NOTE: The circled numbers denote each step while the mechanism on the left represents the use of any alkyl group (R and R') while the mechanism on the right assumes both alkyl groups are methyl. Hence, 2-butyne started the reaction and the final product was trans-2-butene.
Answer:
Element
Explanation:
A chemical element is a substance that contains only one type of atom, which is the smallest particle of an element
Compare it to the chart showing how base or acidic a substance is
Answer: 62.5 mL
Explanation:
The key thing you need to understand here is that chemical reactions depend on reactant particles bumping into each other collision theory
