Answer:
The answer to your question is: 17.26% of carbon
Explanation:
Data
CxHy = 0.2121 g
BaCO₃ = 0.6006 g
Molecular mass BaCO₃ = 137 + 12 + 48 = 197 g
Reaction
CO₂ + Ba(OH)₂ ⇒ BaCO₃ + H₂O
Process
1.- Find the amount of carbon in BaCO₃
197 g of BaCO₃ --------------- 12 g of Carbon
0.6006 g ---------------- x
x = (0.6006 x 12) / 197
x = 0.0366 g of carbon
2.- Calculate the percentage of carbon in the organic compound
0.2121 g of organic compound --------------- 100%
0.0366g -------------- x
x = (0.0366 x 100) / 0.2121
x = 17.26%
When sucrose is hydrolyzed, <u>two reducing groups</u> will be created as the glycosidic linkage is broken. Hydrolyzed sucrose <u>will</u> give a positive Benedict's test. Hydrolysis can be achieved by adding <u>strong acids or enzymes.</u>
<h3>How is sucrose hydrolyzed in the body?</h3>
The reaction that breaks bonds and releases energy is called hydrolysis. It is a significant biological process that causes energy to be released from within our bodies. The human small intestine contains the -glucosidase enzyme sucrase, which hydrolyzes sucrose into its component monosaccharides fructose and glucose. In the brush boundary of the upper gastrointestinal system, roughly 10–25% of the fructose is converted to glucose.
