Answer:
1s2 2s2 2p6 3s2 3p6 4s2 3d5
Explanation:
According to the Aufbau principle, electrons are filled in orbitals in order of increasing energy. The energy of orbitals in the electronic configuration of manganese increases from left to right, hence 3d orbital is much greater in energy than a 3p orbital.
The arrangement of orbitals in order of increasing energy is shown in the answer above.
Answer:
transmutation, conversion of one chemical element into another. A transmutation entails a change in the structure of atomic nuclei and hence may be induced by a nuclear reaction (q.v.), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay .
Answer:
a.
b.
Explanation:
Hello,
a. In this case, we use the Boyle's law as en inversely proportional relationship between pressure and volume:
Thus, for the given conditions, one computes the new pressure as shown below:
b. Now, we should find the final volume for a new pressure of 10 atm:
Best regards.

The indicator, phenolphthalein is added to the analyte as an indicator in acid–base titrations.
Phenolphthalein is a color changing indicator for acid base titrations.
Titration is a quantitative technique used to find concentration of an unknown solution(analyte ) from a solution of known concentration. which is the titrant.
Now the procedure is set up that, the titrant is in the burette and added to the analyte with known volume)in a conical flask in the presence of an indicator till the endpoint of the reaction.
This is marked by a sharp change of color to explain the point when the titrant neutralizes the analyte solution.(phenolphthalein is colorless in acidic solutions but turns pink in basic solutions).
