4 mol / 205g H2O = 4/.205 = 19.5 mol/kg boiling point = 100 + 19.5 • 0.51 = 109 ºC
Answer:
When an element loses an electron, its oxidation number increases.
Explanation:
The oxidation number of an element indicates the hypothetical charge of an atom in a compound. It is hypothetical because, in the context of a compound, the elements may not necessarily be ionic. When the number of electrons associated with an atom changes, its oxidation number also changes. When an element loses an electron, its oxidation number increases.
Answer:
3-ethoxy-3-ethyl-5-methylheptane
Explanation:
In this case, we have to identify the longest chain of carbon in this case the longest chain is made with 7 carbons. Then we have to assign carbon 1. In this case, carbon 1 is the one nearest to the ethoxy group. With this in mind, we will have a methyl on carbon 5, a methyl on carbon 3 and an ethoxy group in carbon 3, so the name would be 3-ethoxy-3-ethyl-5-methylheptane.
See figure 1
I hope it helps!
Steps 1 and 3 are correct rate
Answer:
The first step is - option A) an acid base reaction.
Explanation:
The direct reaction of a carboxylic acid with an amine to form an amide is expected to be difficult as it would deprotonate the carboxylic acid and make a nonreactive carboxylate.
The first step in this reaction would be an acid - base reaction as protonation of the carbonyl carbon, that involves the interchange of proton in between electric charge or neutral compound, it is also known as protonation or deprotonation. The acid base reaction is followed by the nucleophilic attack on the carbonyl carbon.
Thus, The first step is - option A) an acid base reaction.
