Answer:
Ionic Exergonic
Explanation:
Exergonic reactions have negative Gibbs free energy and hence are spontaneous.
Endergonic reactions have negative Gibbs free energy and are non-spontaneous and low temperature.
Endergonic reactions require external supply of energy. But such reactions can be made spontaneous or favorable by coupling with exergonic reaction via a common intermediate.
Therefore, the correct answer is Ionic Exergonic.
Answer:
- <em>the electron configuration for P iin complete form in order of increasing orbital energy is: 1s² 2s² 2p⁶ 3s² 3p³ </em>
Explanation:
As stated, <em>writing the symbol for the occupied subshell and adding a superscript to indicate the number of electrons in that subshell is a common way to represent the electron configuration of the atoms</em>.
There are several rules that you have to follow to write such electron configurations. I will explain the needed to write the electron configuration for the atoms of P (phosphorus) in the requested form.
1) <u>First, determine the number of electrons of the atom</u>:
- Use the atomic number. Phosphorus has atomic number 15.
- The atomic number is the number of protons. So, phosphorus has 15 protons.
- A neutral atom has the same number of electrons than protons. So, phosphorus atoms have 15 electrons.
2)<u> Fill the orbitals in order of incrasing orbital energy</u>
- Aufbau rules are very helpful. As per it this is the order of the orbitals:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ ...
- 15 electrons ⇒ <u>1s² 2s² 2p⁶ 3s² 3p³</u>
- Check the number of electrons: 2 + 2 + 6 + 2 + 3 = 15
- Hence, that is the electron configuration for P iin complete form in order of increasing orbital energy.
3) Other rules that you must consult to deal with some special issues of the electron configurations are: the exclusion principle of Pauli and the Hund's rule, but they are beyond the interest of this question.
Answer: The percentage of juice present in new punch is 62.5 %.
Explanation:
In 20 cup of punch = 75 % of juice
Cup of juices in 20 cup of punch =
of juice
After addition of 4 cups of water the total volume of punch becomes:
= (15 cups of juice + 5 cups of water)+ (4 cups of water added more) = 24 cups
Percentage of the juice in new punch juice is:
The percentage of juice present in new punch is 62.5 %.
