Answer:
from the pic:
since molar mass is 118.084 g/mol;
It is an aldehyde with structure ( second pic )
Yes they do have valence electrons.
Answer:
- <u>44.5 g</u> <em>of solute are contained in 356g of a 12.5%(w/w) solution.</em>
<em />
Explanation:
12.5% (w/w) is the mass/mass percentage concentration of the solution.
- %(w/w) = (mass of solute/mass of solution) × 100
Subsititue with:
- <em>mass of solution 356g</em>
And solve for the<em> mass of solute</em>:
- 12.5 = (mass of solute / 356g) × 100
- mass of solute = 12.5 × 356g / 100 = 44.5 g ← answer
Answer:
Option D: Carbohydrates
Explanation:
Carbohydrates are a group of macromolecules that are a vital energy source for the cell, provide structural support to many organisms, and can be found on the surface of the cell as receptors or for cell recognition.
