b. neutral.
c. weakly basic.
d. strongly basic.
A solution with a pH of 8.0 is weakly basic. Thus ,the correct option is C.
The pH scale gives the measure of the acidity or basicity of a solution. It ranges from 0 to 14, where a pH of 7 is considered neutral. Solutions which have a pH less than 7 are acidic, while solutions which have a pH greater than 7 are basic.
In this case, since the pH is 8.0, which is greater than 7, the solution is basic. However, it is important to note that the basicity of the solution is weak, as it is only slightly above neutral.
For example, think of a pH of 8.0 as being similar to water from a freshwater lake. It's not strongly basic like bleach or ammonia, but it still has a slightly basic nature compared to a neutral solution.
Thus, the correct option is C.

The half life of sodium -24 is 15 hour.
The duration needed for an amount to decrease to half its original is known as the half-life.
Sodium is a kind of element which has atomic number 11. It has three isotopes.
The radioactive isotope sodium-24, which is employed in blood tests in medicine, degrades through beta decay as well as seems to have an of 15.0 hours.
Therefore, the half life of sodium -24 is 15 hour.

In addition, predict under what temperatures (all temperatures, low temperatures, or high temperatures), if any, the reaction in part D will be spontaneous
A) The reaction is spontaneous at all temperatures.
C) The reaction is spontaneous at high temperatures.
D) The reaction is nonspontaneous at all temperatures.
-linear
-trigonal planar
-tetrahedral
-trigonal bipyramidal
-octahedral
-bent (angular)
Covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule.
Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
Using VSEPR and electron pair repulsion, we can easily find that linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule if we assume that all of the atoms attached to the central atom were identical. Any geometries which have center of symmetry will produce non polar molecule.
Therefore, linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule.

Question
Answer:
The answer is D
Mn and Al3+
Al and Mn
Mn2+ and Al3+
The reactants that would lead to a spontaneous reaction are Mn2+ and Al3+. Al and Mn are not because they are stable reactants. Mn and Al3+ are not because Mn is stable. Mn2+ and Al are not because Al is stable.
