<span>Fischer projection for D-2-ketotetrose is in Word document below.
</span>D-2-ketotetrose is monosaccharide, having both a ketone (a ketose) and four carbons (a tetrose). There are two ketotetroses (the enantiomers) L and D-erythrulose, this is D-erytrhrulose (1,3,4-trihydroxy-2-butanone).
The <span>Fischer projection is </span>two-dimensional<span> representation of a </span>three dimensional organic molecule.
To solve for moles use molar and volume:
M = mol/L
0.02700 m= mol/(.75 L)
mol = .036 mol of Hg(NO3)2
The proportion of Hg(NO3)2 to the Mercury that is used to create
HgS is 1:1 so solve for the moles of Mercury used. So:
.036 * (1 Hg(NO3)2 / 1 Hg) = .036 moles of Hg used to make
HgS
The proportion of Mercury to HgS is 1:1, as an alternative
of doing the obvious math you can conclude that .036 moles of HgS will be
produced because you're given .036 moles of Hg and an excess of S. Use the
molar mass of HgS to determine how many grams will be produced.
.036 moles * 232.66 g/mol = 8.37576 grams of Vermilion is
produced.
I'm sorry I'm not quit sure
Answer:
The answer is 8 grams of Oxygen
Explanation:
This is because Oxygen atomic mass is 16 and hydrogen mass is 2.
16/2=8
So,
The Lewis structure for ethylene is two carbons double-bonded to each other, and two hydrogens single-bonded to each carbon atom.
Each bond symbolizes two shared valence electrons. Since the carbon atoms are double-bonded, they share four (4) valence electrons (the other electrons are in lower energy levels and do not appear because they typically don't react when higher energy-level electrons are on top of them).
