Ernest Rutherford's gold-foil experiment showed which of the following?

Answers

Answer 1

Answer: Ernest Rutherford's gold-foil experiment showed the density of atoms.
The experiment proved that most of an atom is empty space with a very small positively charged nucleus in the middle.
So, from the given statements he following is true:
Ernest Rutherford's gold-foil experiment showed the existence of a dense, positively charged center in an atom.

A real gas behaves least like an ideal gas under the conditions of(1) low temperature and low pressure
(2) low temperature and high pressure
(3) high temperature and low pressure
(4) high temperature and high pressure

Answers

The correct answer is option 3. A real gas behaves least like an ideal gas under the conditions of high temperature and low pressure. At this temperature and pressure, the molecules are close to each other and collisions or interactions are very likely to happen which is not an ideal gas.

What is the property of flowing very quickly in a liquid?

Answers

The answer is Fluidity.
Fluidity is the physical property that enables a substance to flow. Fluidity also refers to the state of being fluid. So basically, solid molecules has no fluidity. It is also believed that the fluidity of water increases as the water gets warmer.

how much potassium bromide, in grams, should be added to water to prepare 0.50 of solution with molarity of 0.125M?

Answers

Volume = 0.50 L

Molar mass KBr = 119.002 g/mol

Molarity = 0.125 M

Mass ( KBr) = ?

mass = molarity * molar mass * volume

mass = 0.125 * 119.002 * 0.50

mass = 7.437625 g of KBr

hope this helps!

If the Kelvin temperature of a gas is tripled and the volume if doubled, the new pressure will be ___. A. 3/2 the original pressure B. 1/6 the original pressure C. 5 times the original pressure D. 2/3 the original pressurethe answer isnt b or c

Answers

The answer is 3/2 the original pressure. The concept behind this is the ideal gas law wherein it states that Pressure (P) times volume(V) is equal to number of moles (n) times ideal gas constant (R ) times temperature (T). Since you’re trying to calculate for the pressure you use P=nRT/V. Input 3 to Temperature and 2 to volume. You’ll get a pressure of 3/2 which is 3/2 times the original pressure.
