Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them.
53.3% + 6.7% = 60%, 100% - 60% = 40%. 40% of glucose is made of carbon. Since there are only three types of atoms in glucose, and the amount of hydrogen and oxygen is already given, this means that whatever percentage is left (40%) has to be carbon.
12.7% NaCl
Hello, I believe this question is talking about the mass percentage of sodium chloride and we must use stoichiometry and then divide by the total mass of the mixture
This is what I did
0.12g Na x 1/22.99 x 1NaCl/Na x 58.44/1
This will result in 0.305 grams
When then divide this by 2.4
0.305/2.4 = 0.127, then multiply by 100
12.7%
Answer:
X. 80°
Explanation:
if the substance is below -38 then it is in the solid phase (-100° and -50°) and if it is above 356° it is a gas (375°). Therefore anything in the middle is a liquid, 80°.
