Answer:
A) homotopic and B) enantiotopic
Explanation:
Protons chemically equivalent are those that have the same chemical shift, also if they are interchangeable by some symmetry operation or by a rapid chemical process.
The existence of symmetry axes, Cn, that relate to the protons results in the protons being homotopic, that is chemically equivalent in both chiral and aquiral environments.
The existence of a plane of symmetry, σ, makes the protons related by it, are enantiotopic and these protons will only be equivalent in an aquiral medium; if the medium is chiral both protons will be chemically NOT equivalent. The existence of a center of symmetry, i, in the molecule makes the related protons through it enantiotopic and therefore chemically only in the aquiral medium.
Diastereotopic protons cannot be interconverted by any symmetry operation and they are different, with different chemical displacement.
Answer : Yes , H2SO4 is an arrhenius acid
<h2>Explanations : </h2>
• An ,Arrhenius acid ,is a substance that ,dissociates, in water to form ,hydrogen ions (H+).
,
• In other words, an arrhenius acid increases the H+ ion concentration in aqueous solution.
,
• This can be represented by the equation :
• Therefore, H2SO4 is a strong arrhenius acid.
Answer:
A balanced chemical equation represents a chemical reaction that obeys the Law of Conservation of Mass (Matter). It can be thought of as describing how many atoms or molecules of reactants are consumed in order to produce a certain number of atoms or molecules of products.
Answer:12 cm^3 becoz as per Gay-Lussac law
H2+Cl2---. 2HCl thus ratio is 1:1:2
Explanation:
I believe you can simply add more cells in series to get a higher voltage. Not 100% sure on that.
