Answer:
No, just because carbon did not react with water, does not mean it wouldn't react with a different compound.
Explanation:
It is common knowledge that carbon is not in group 18, because it is found in all living compounds, and this means it must be reactive with many compounds. We know that water is not very reactive, but it is a good solvent. Meaning that many compounds can dissolve in water, but not chemically react with it. Carbon however is not very soluble because it does not create dipoles or hydrogen bonds. This means it will not show any change when in the presence of water, but if combined with oxygen, can form carbon dioxide.
Answer:
Amount of sugar in solution = 82.5 gram
Explanation:
Given:
Sugar in solution percentage = 15%
Total solution = 550 grams
Find:
Amount of sugar in solution
Computation:
Amount of sugar in solution = Sugar in solution percentage x Total solution
Amount of sugar in solution = 15% X 550
Amount of sugar in solution = 82.5 gram
The average atomic mass in amu of element X is 58.42 amu
The average atomic mass is the sum of the mass number of each of the isotopes multiplied by their respective abundances.
So;
The average atomic mass of element X is;
(58 * 0.68) + (60 * 0.26) + (0.06 * 62)
= 39.44 + 15.26 + 3.72
= 58.42 amu
The average atomic mass in amu of X is 58.42 amu.
