Because I (iodide) is better leaving group than Cl, so it will leave when this molecule is reacted with strong base (sodium tert-butyl oxide) giving the elimination product provided in picture<span />
Glucose, one type of monosaccharide, is represented by the chemical formula, c6h12o6. if you were to put together 2 glucose mole
cules, why wouldn't the molecular formula for the newly made disaccharide be c12h24o12
2 answers:
Answer:
This is because of the removal of water molecule during condensation reaction between two glucose molecules.
Explanation:
The molecule of glucose has molecular formula of.
When two molecules of monosaccharide adds up together they form disaccharide molecule of carbohydrate. During the addition of two monosaccharides condensation reaction occurs in which removal of small molecule like water takes place.

Answer:- 14.9 M
Solution:- Given commercial sample of ammonia is 28% by mass. Let's say we have 100 grams of the sample. Then mass of ammonia would be 28 grams.
Density of the solution is given as 0.90 grams per mL.
From the mass and density we could calculate the volume of the solution as:
= 111 mL
Let's convert the volume from mL to L as molarity is moles of solute per liter of solution.
= 0.111 L
Now, we convert grams of ammonia to moles on dividing the grams by molar mass. Molar mass of ammonia is 17 gram per mole.
= 1.65 mole
To calculate the molarity we divide the moles of ammonia by the liters of solution:
= 14.9 M
So, the molarity of the given commercial sample of ammonia is 14.9 M.
