Answer:
A. The ratio of the element in glucose is different than in ethanol
Explanation:
The compounds given are;
Glucose C₆H₁₂O₆
Ethanol C₂H₆O
The two compounds given are different from one another. But they have the same elemental composition.
Ethanol is made up of Carbon, hydrogen and Oxygen and so also, Glucose
Now,
The number of atoms in both compounds are different;
Number of atoms
C H O
Glucose 6 12 6
Ethanol 2 6 1
Answer:
Farthest from the carbonyl carbon.
Explanation:
Reference carbon that determined the absolute D and L configuration is located farthest from the carbonyl carbon.
In other words, reference carbon is that assymentric carbon which is located farthest from the carbolyl carbon and has configuration similar to D- or L-glyceraldehyde isomers.
D and L configuration is decided by the direction of -OH group attached to the reference carbon.
In L-isomer, -OH group is attached to the left side of the reference carbon and in D-isomer, -OH group is attached to the right side of the reference carbon.
The element is Magnesium
- It has total 12 electrons
it has electronic configuration

or

In valence cell it has 2 electrons and therefore its valency is 2
Answer: 5.72 g mass of carbon dioxide was produced
Explanation:

Moles of C =
Mass of
reacted = 59.1 g - 17.5 g = 41.6 g
Moles of 
According to reaction 1 mole
produces 1 mole of
then 1.3 mole of
will produce
moles of 
Mass of
:
=Moles of
× molar mass of
= 1.3 ×44 g/mol =
=57.2 grams
5.72 g mass of carbon dioxide was produced
