The answers to your questions:
1: B.
2: True
Answer:
Ionic bonding is the complete transfer of valence electron(s) between atoms and is a type of chemical bond that generates two oppositely charged ions. By losing those electrons, these metals can achieve noble-gas configuration and satisfy the octet rule

Answer:
Sulfur ₁₆S³²
Explanation:
The sulfur have sixteen protons sixteen neutrons and sixteen electrons. The sum of neutrons and protons is equal to atomic mass. So the given element have sixteen protons and sixteen electron, the atomic mass would be 32 and the element with atomic mass 32 is sulfur.
The number of electrons are equal to the number of protons. In the given element two electrons are more than number of protons. It means element gain two extra electron from another element and it is present in ionic form.
It is present in given form:
S²⁻
Electronic configuration:
S₁₆ = [Ne] 3s² 3p⁴
To complete the octet sulfur gain two electrons from other element and get stable.
Answer:
92.6%
Explanation:
Hello there!
In this case, according to the first-order kinetics, we can write:
Whereas we need to know the rate constant in order to compute the percentages, given the half-life:
In such a way, we can now compute the fraction in which the reaction has been completed after 3 hrs:
And the percent would be 92.6% after multiplying the fraction by 100 %.
Best regards!
