maxonik [38]

Answer:

Bohr's model

Explanation:

Rutherford's experimental evidence best supports the Bohr's model. Recall that in the Bohr's model, the Rutherford model was regarded as a fundamental stepping stone.

Experimental evidence from the Bohr's model shows that the atom is not a sphere of positive charges in which negative charges were embedded. It would have been impossible for Neils Bohr to build the quantum theory from such a model.

Hence, the nuclear theory of Rutherford provided a fundamental stepping stone and experimental backup for the Bohr's model of the atom.

All other models mentioned in task 1 (Dalton, Thompson and Bohr) all mention the fact that the atom is made of particles. Thompson effectively described the particles as negative and positive in nature. Bohr took the idea further by proposing that the negative particles (electrons) were actually found in energy levels that are quantized.

Which bonds are formed when elements share electrons and form molecules?.
Nimfa-mama [501]

Answer:

A covalent bond

Explanation:

the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

A 8.96-L sample of gas has a pressure of 1.86 atm and a temperature of 94 °C. The sample is allowed to expand to a volume of 11.
Varvara68 [4.7K]

Answer:

Explanation:

Explanation:

All you have to do here is use the ideal gas law equation, which looks like this

P

V

=

n

R

T

−−−−−−−−−−

Here

P

is the pressure of the gas

V

is the volume it occupies

n

is the number of moles of gas present in the sample

R

is the universal gas constant, equal to

0.0821

atm L

mol K

T

is the absolute temperature of the gas

Rearrange the equation to solve for

T

P

V

=

n

R

T

⇒

T

=

P

V

n

R

Before plugging in your values, make sure that the units given to you match those used in the expression of the universal gas constant.

In this case, the volume is given in liters and the pressure in atmospheres, so you're good to go.

Plug in your values to find

T

=

3.10

atm

⋅

64.51

L

9.69

moles
