Answer : The isoelectronic groups are:
Explanation :
Isoelectronic : It is defined as the compound or molecule having the same number of electrons and the same number of electronic structure.
- The element is helium. The number of electrons are 2.
- The element is beryllium. The number of electrons are 4. The number of electrons in = 4 - 2 = 2
- The element is lithium. The number of electrons are 3. The number of electrons in = 3 - 1 = 2
- The element is nitrogen. The number of electrons are 7. The number of electrons in = 7 + 3 = 10
- The element is neon. The number of electrons are 10.
- The element is sulfur. The number of electrons are 16. The number of electrons in = 16 + 2 = 18
- The element is magnesium. The number of electrons are 12. The number of electrons in = 12 - 2 = 10
- The element is titanium. The number of electrons are 22. The number of electrons in = 22 - 4 = 18
- The element is potassium. The number of electrons are 19. The number of electrons in = 19 - 1 = 18
The isoelectronic groups are:
Move anywhere and can be anywhere while it is in that phase
The student's test average is : 0.92
Total score obtained = 369
Number of tests = 4
Since Each test is exactly 100 points ;
The total score obtainable is (100 × 4) = 400
Average = score obtained / total score obtainable
Average = 369 / 400
Average = 0.9225
Average = 0.92

Answer:
10 L
Explanation:
The only variables are pressure and volume, so we can use Boyle's Law:
p1V1 = p2V2
Data:
p1 = 125 atm; V1 = 4.0 L
p2 = 50 atm; V2 = ?
Calculation:
125 × 4.0 = 50V2
500 = 50 V2
V2 = 500/50 = 10 L
The new volume will be 10 L.
