Answer:
The correct answer is - n and l.
Explanation:
The size of an orbital is determined by the principal number of shell which is represented by n. The larger the energy level (n) bigger the size of the orbital. N can be any integer value: 1, 2, 3 . . . . and so on.
l represents the angular momentum or subshell number provides the overall shape of an orbital in this subshell only integer values between 0 and n-1 are permitted.
Thus, n & l are two quantum numbers that determine the energy level of an orbital in a multielectron atom.
Answer:
Dear, your answer is
solubility is affected by current concentration, mechanical disturbance, temperature and pressure. So the answers are:
- Increasing temperature decreases the solubility of gases.
- Stirring increases the solubility of solids.
- Increasing pressure increases the solubility of gases.
- Decreasing the amount of solvent decreases the solubility of solids, liquids, and gases.
Answer:
7.52 × 10⁻¹⁴ mi
Explanation:
Step 1: Given data
Bond length between two carbon atoms (l): 121 pm
Step 2: Convert "l" to meters
We will use the conversion factor 1.00 m = 1.00 × 10¹² pm.
121 pm × (1.00 m / 1.00 × 10¹² pm) = 1.21 × 10⁻¹⁰ m
Step 3: Convert "l" to miles
We will use the conversion factor 1.00 mi = 1609.34 m.
1.21 × 10⁻¹⁰ m × (1.00 mi / 1609.34 m) = 7.52 × 10⁻¹⁴ mi
PH + poH = 14
6.2 +poH = 14
poH = 7.8
