Alkenes undergo
Electrophillic Addition Reactions. Electrophiles are added across double bond. In given reaction the
H⁺ is first added across double bond as the double bond being denser in electron density act as a neucleophile. A
carbocation formed depends upon the nature of Alkene, if alkene is
symmetrical (as in our case) then positive charge can get any position, but in case of
unsymmetrical alkene the positive charge will go to that carbon which is attached to more carbon atoms. Then the water molecule attacks the carbocation and forms
alcohol.
The volume of apple juice could a diabetic person drink : 100 ml
<h3>Further explanation</h3>
Given
sugar allowance = 8 g
sugar concentration of apple juice : 8.0% w/v
Required
Volume of apple juice
Solution
The concentration of a substance can be expressed in several quantities The concentration shows the amount of solute in a unit of the amount of solvent.
% w/v = mass of solute (weight) in g / 100 ml solution
So for 8% w/v = 8 g of sugar(solute) in 100 ml of apple juice
Explanation:
Given parameters:
Dimension = 8.5in²
we are to convert from in² to cm²
in² = in x in
cm² = cm x cm
1 in = 2.54cm
Using dimensional analysis;
8.5in² x 
= 54.84cm²
We solved this problem using dimensional analysis where we multiplied the unit with 1.

Answer:
[Na⁺] = 1.99 M
Explanation:
Na₂S is a ionic salt that can be dissociated.
Dissociation equation is:
Na₂S → 2Na⁺ + S⁻²
1 mol of sodium sulfide can give 2 moles of sodium cation.
We convert moles of salt: 78 g . 1mol / 78.06 g = 0.999 moles
As ratio is 1:2, after dissociation we have (0.999 . 2) = 1.998 moles of Na⁺
Molarity is a type of concentration.
It indicates moles of solute in 1 L of solution and in this case, we have 1 L as final voulme.
Moles of Na⁺ are 1.998 moles. Then molarity (mol/L) is:
M =1.99 mol/L
