Alpha particles were deflected by the positively charged

Chemistry
1 answer:
AysviL [449]3 years ago
6 0

Answer:

See explanation

Explanation:

In Rutherford's experiment, a gold foil was bombarded with positively charged alpha particles. A zinc sulphide screen was used to observe the movement of the alpha particles during the experiment.

A few particles passed through without deflection while some particles were deflected through large angles.  This observation led Rutherford to the conclusion that the atom was made up of a dense positively charged nucleus where most of its mass was concentrated.

32.7 grams of water vapor takes up how many liters at standard temperature and pressure (273 K and 100 kPa)?
kotegsom [21]
Under standard temperature and pressure conditions, it is known that 1 mole of a gas occupies 22.4 liters.

From the periodic table:
molar mass of oxygen = 16 gm
molar mass of hydrogen = 1 gm
Thus, the molar mass of water vapor = 2(1) + 16 = 18 gm

18 gm of water occupies 22.4 liters, therefore:
volume occupied by 32.7 gm = (32.7 x 22.4) / 18 = 40.6933 liters
