Hello there!
In this case, since these mole-mass relationships are understood in terms of the moles of the atoms forming the considered compound, we first realize that the chemical formula of the cobalt (III) nitrate is Co(NO₃)₃ whereas there is a 1:1 mole ratio of the cobalt (III) ion (molar mass = 58.93 g/mol) to the entire compound. In such a way, we first compute the moles of the salt (molar mass = 58.93 g/mol) and then apply the aforementioned mole ratio to obtain the grams of the required cation:
Best regards!
<h3><u>Answer;</u></h3>
Both aldehydes and ketones can hydrogen bond with water molecules. ethanal has a higher BP than ethane ketones are polar molecules
<h3><u>Explanation;</u></h3>
- An aldehyde differs from a ketone by having a hydrogen atom attached to the carbonyl group, which makes aldehydes very easy to oxidise.
- Ketones lack hydrogen atom and are resistant to oxidation and are only oxidised by powerful oxidising agents which have the ability to break carbon-carbon bonds.
- <em><u>Both aldehydes and ketones are polar molecules because of the presence of the carbon-oxygen double bond, which means they can form hydrogen bonds with water molecules</u></em>.
