Answer:
Here’s what I get.
Explanation:
J. J. Thomson proposed that the electrons in an atom were embedded within a sphere of uniform positive charge, much like the raisins in a plum pudding (North Americans would call it a Christmas cake).
If that were the case, Rutherford reasoned, a stream of α particles should pass through the atom with little deflection.
Rutherford had his graduate students, Geiger and Marsden, shoot α particles through a thin gold foil.
Most of the particles passed through with little deflection, but a few rebounded back towards the emitter.
Rutherford concluded that most of the mass and all the positive charge in an atom was concentrated in a central nucleus with a cloud of electrons orbiting it like planets circling about the Sun.
His model is now called the nuclear model or the planetary model of the atom.
Theory. It might be disproved in the future, so it can not be a law until it solid as a rock. Brainliest the answer and I will explain more.
When sodium chloride is molten:
NaCl ------> Na⁺ +Cl⁻
Anod (+) | Cathode (-)
2Cl⁻-2e⁻ ---> Cl2(gas) | Na⁺ + e⁻ -----> Na⁰(s)
Volvox and paramecium live in the same living conditions. The visible difference between volvox and paramecium is
the shape. <span>Volvox is rounded, while paramecium is lying</span>.
Answer:
The answer to your question is 0.62 atm = 62.82 kPa = 471.2 mmHg
Explanation:
Data
P = 0.62 atm
P = ? kPa
P = ? mmHg
Process
1.- Look for the conversion factor of atm to kPa and mmHg
1 atm = 101.325 kPa
1 atm = 760 mmHg
2.- Do the conversions
1 atm ----------------- 101.325 kPa
0.62 atm ------------ x
x = (0,62 x 101.325) / 1
x = 62.82 kPa
1 atm ------------------ 760 mmHg
0.62 atm ------------ x
x = (0.62 x 760)/1
x = 471.2 mmHg
