Answer:
The formula of the compound is Cu₂O.
Explanation:
From the question given above, the following data were obtained:
Mass of compound = 12.5 g
Mass of copper (Cu) = 11.1 g
Mass of oxygen (O) = 1.4 g
Formula of compound =?
The formula of the compound can be obtained as follow:
Cu = 11.1 g
O = 1.4 g
Divide by their molar mass
Cu = 11.1 / 63.5 = 0.175
O = 1.4 / 16 = 0.0875
Divide by the smallest
Cu = 0.175 / 0.0875 = 2
O = 0.0875 / 0.0875 = 1
Therefore, the formula of the compound is Cu₂O.

d. Training material: This one is also used inside the workplace
e. Blogs: The blog is an article in which the health and related data could be written and provided
Therefore these all the resources are used inside the organization
Answer: alcohols
Explanation:
The carbonyl group refers to C=O. It is contained in aldehyde, Ketones, carboxylic acids , esters, amides and acyl chlorides. They are not found in alcohols. The alchols are generally ROH. They do not contain any carbon-oxygen unsaturated bond in their structure hence the answer.
