Which of the following most accurately states the sequence of monosaccharide digestion and absorption?
A. Monosaccharides are first converted to glucose in the small intestine and then the glucose enters the blood stream through the liver. B. Monosaccharides are absorbed by the small intestine and sent to the liver to be converted to glucose, which then travels to the blood stream.
C. Monosaccharides are absorbed directly into the blood stream through the small intestine.
D. Monosaccarides undergo condensation reactions in the small intestine and then are absorbed into the blood stream through the liver.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

i just learnt this recently but i need to look through my notes again

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
