Alright my friend so protons along with neutrons will be found in the Nucleus <span />
For that you have to use the Aufbau principle
For example, writing the electronic configuration of Fe(28)
I recommend that you memorize the aufbau principle. Once you learn it, you don’t need anything else except the atomic number of the element to write it’s electronic configuration.
Answer:
The boiling point of the solvent above a solution change from that of the pure solvent is directly proportional to the molal concentration of the solute
Explanation:
Answer:
P₂ = 607 mmHg
Explanation:
Given data:
Initial volume = 4.5 L
Final volume = 5.6 L
Initial pressure = 756 mmHg
Final pressure = ?
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
756 mmHg × 4.5 L = P₂ × 5.6 L
P₂ = 3402 mmHg. L/5.6 L
P₂ = 607 mmHg
