Which nonmetal would an ion of Ca2+ MOST LIKELY ionically bond with in a 1:1 ratio?
2 answers:
Explanation:
Atomic number of calcium is 20 and its electronic configuration is 2, 8, 8, 2.
Since it has two extra electrons, therefore, it donate these electrons to an electron deficient atom that needs only two electrons to complete its octet.
Oxygen atom has electronic configuration 2, 6. Hence, it is the atom that needs two electrons to complete its octet. So, it forms a compound of calcium oxide (CaO).
Thus, oxygen will most likely ionically bond with in a 1:1 ratio with .

Answer:
(d) 3,7-dimethyl-4-nonyne.
Explanation:
Hello,
In this case, considering the attached picture on which you can see that the main chain has nine carbon atoms, one tripe bond at the fourth carbon and two methyl radicals at the third and seventh carbons respectively, by following the IUPAC rules, the name would be: (d) 3,7-dimethyl-4-nonyne since the chain must start at the side closest to the first triple bond due to its priority and subsequently considering the present radicals.
Best regards.
