The correct answer for the question that is being presented above is this one: "b. positive" Eugen Goldstein discovered in 1886 that atoms also have positive charges. He was a German physicist and an early investigator of discharge tubes. He also discovered the anode rays.
Answer : -19.6
Explanation : We can calculate this using the combine equation of boiling point and depression in freezing point and obtain a combined equation which is
∆T(f) = ∆T(b) x {K(f) / K(b)} ;
Where ∆T(f) is depression in freezing point,
∆T(b) is elevation in boiling point,
K(f) is cryoscopic constant for water it is 1.86
K(b) is ebullioscopic constant for water it is 0.512
So we can solve the equation,
∆T(f) = (105.4 -100) X 
= 19.6
So when we have the freezing point depression as 19.6,
we know water freezes at 0° C so the freezing point will be 0 - 19.6 = -19.6 °C
There are three subatomic particles known: (1) electron which is found outside the nucleus of an atom and (2 and 3) protons and neutrons which are both inside the nucleus. As they are outside the nucleus, it is easier to transport electron than any other subatomic particle. Thus, atom and its ion differ in the number of electrons.
Answer:
Photosynthesis is the process in which plants harness energy from the sun to make their own nutrition. The process converts light energy into chemical energy through cellular respiration.
