Answer:
the answer is D i believe. i am not shure but im like 70% sure
Answer:
The energy of atomic orbitals increases as the principal quantum number, n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of l differ so that the energy of the orbitals increases within a shell in the order s < p < d < f.

Answer:
Mass = 713.4 ×10⁻⁴ g
Explanation:
Given data:
Number of moles of calcium phosphate = 2.3×10⁻⁴ mol
Mass of calcium phosphate = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of calcium phosphate is 310.18 g/mol
by putting values,
2.3×10⁻⁴ mol = mass / 310.18 g/mol
Mass = 2.3×10⁻⁴ mol × 310.18 g/mol
Mass = 713.4 ×10⁻⁴ g
Answer:
397782000 m²
Explanation:
Given data:
123000 m × 3234 m =?
Solution:
123000 m × 3234 m = 397782000 m²
when we multiply the given quantities having same unit i.e meter the answer should be m² . It could be the area, and its unit is m².
Area = length (m) × width (m)
Answer is s orbital. Hopes this helps
