Answer:
C. Among the metals
Explanation:
The best place to look for this element that has this property is among the metals.
The ability of a metal to be malleable and possibly drawn to a sheet is a manifestation of their metallic bonding. Metallic bonds are very predominant among metals and their alloys.
This bond type determines the bulk of the physical properties of metals.
One of such is their ability to drawn into thin sheet, it is called malleability.
Lead (Pb) has the electron configuration [xe] 6s2 4f14 5d10 6p2.
<h3><u>
What is electronic configuration ?</u></h3>
A neutral element's total number of electrons is represented by its electronic configuration. To get the total number of electrons in an atom, we sum all the superscripts.
As the last electron enters the p orbital, the provided element is a p block element. Xenon, a noble gas with 54 electrons, is the closest.
According to Afbau's rule, the electrons are filled in the sequence of increasing energies, and the electronic configuration in terms of the noble gs configuration is as follows:
Total electrons = 54 + 2 + 14 + 10 + 2 = 82
Lead is the element with the symbol whose atomic number is 82 since it contains 82 electrons.

Answer:
Explanation:
The following equation describes the oxidation of ethanol to aceticacid by potassium permanganate:
3C2H5OH +4KMnO4-->3HC2H3O2 +4MnO2 + 4KOH + H2O
5.0 g of ethanol and an excess of aqueous KMnO4 arereacted, and 5.9 g HC2H3O2 result.What is the percent yield?
a. 100%
b. 91%
c. 67%
d. 30%
e. 5.9 g HC2H3O2 is impossible since it represcents more than a100% yield.
