Answer:

Here's what I find.

Explanation:

Many scientists contributed to our model of the atom.

Among those who received the Nobel Prize for their work are:

1906 — J.J. Thomson — discovery of the electron

1908 — Ernest Rutherford — nuclear model of the atom

1922 — Niels Bohr — planetary model of the atom

1922 — Albert Einstein — quantum mechanical model of the atom

1935 — James Chadwick — discovery of the neutron

What is the frequency of a wave with a wavelength of 6.40 x 104 meters??

Zina [86]

Answer:- $4.69*10^3Hz$

Solution:- Wavelength is given and we are asked to calculate the frequency. The equation that correlates frequency with wavelength is:

$\nu =\frac{c}{\lambda }$

where, $\nu$ is the symbol for frequency, c is the symbol for speed of light and $\lambda$ is the symbol for wavelength.

Speed of light is $3.0*10^8\frac{m}{s}$ and the wavelength is given as $6.40*10^4m$ .

Let's plug in the values in the equation and so the calculations to calculate the frequency:

$\nu =\frac{3.0*10^8(\frac{m}{s})}{6.40*10^4m}$

$\nu =4.69*10^3Hz$

(since, $\frac{1}{s}=Hz$ )

So, the frequency of the wave is $4.69*10^3Hz$ .

When 5ml of HCl was added

777dan777 [17]

Answer:

A. There was still 140 ml of volume available for the reaction

Explanation:

According to Avogadro's law, we have that equal volumes of all gases contains equal number of molecules

According to the ideal gas law, we have;

The pressure exerted by a gas, P = n·R·T/V

Where;

n = The number of moles

T = The temperature of the gas

R = The universal gas constant

V = The volume of the gas

Therefore, given that the volumes and number of moles of the removed air and added HCl are the same, the pressure and therefore, the volume available for the reaction will remain the same

There will still be the same volume available for the reaction.

A substance has twice the number of particles as 12 grams of carbon-12. How many

klasskru [66]

Answer:

D)2.0

Explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by $N_0$ .

Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.

Avogadro constant:-

$N_a=6.023\times 10^{23}$

Thus,

Number of particles as 12 grams of carbon-12 constitutes 1 mole

<u>Twice the number of particles as 12 grams of carbon-12 constitutes 1*2 mole</u>

Thus, moles in the substance = 2.0 moles
