Answer:
χsolvent = 1.0000 - 0.1000 = 0.9000
Use Raoult's Law:
Psolution = (χsolvent) (P°solvent)
x = (0.900) (25.756)
x = 23.18 mmHg (to four sig figs)
Protons are positive
Neutrons are neutral
Electrons are negatively charged
The name given to these electrons are that they are valence electrons or binding electrons as these are directly involved in chemical Bonding and allow for different compounds to be made.
Answer:
P = 1/8
Explanation:
The wave function of a particle in a one-dimensional box is given by:

Hence, the probability of finding the particle in the one-dimensional box is:


Evaluating the above integral from x₁ = 0 to x₂ = L/8 and solving it, we have:
Solving for n=4:

Answer : The heat of the reaction is -221.6 kJ
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter


where,
= heat released by the reaction = ?
= heat absorbed by the calorimeter
= specific heat of calorimeter = 
= change in temperature = 
Now put all the given values in the above formula, we get:


As, 
So, 
Thus, the heat of the reaction is -221.6 kJ
