Answer:
protons, neutrons, electrons
Answer:

Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the vapor pressure of pure toluene by using the Raoult's law as shown below:

Thus, we solve for the mole fraction of benzene in the vapor phase first:

Which means that the mole fraction of toluene in the vapor phase is 0.24, and therefore, the vapor pressure of pure toluene turns out to be:

Regards!
The answer is 40.5.
Standard form is in answered or not in a different form.
So, you must solve this.
4.05 * 10 = 40.5
Have a great day :) Let me know if you need help with anything else!
Answer:
highest first ionization energy - Br
smallest atomic size - Br
most metallic character - Na
Explanation:
Ionization energy of Br is higher than P because higher zeff value
Sodium is more metallic than calcium because it is able to loose electron more readily as compared to calcium because of higher electro positivity.
Atomic radius of Br is the smallest as its atomic radius is 114, P (115), Ca (197), Na (186)
