define atomic number ​

Answers

Answer:

the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.

As the number of protons increases but the distance between the protons and electron REMAINS THE SAME...
O the electronegativity stays the same.
O the electronegativity decreases.
O the electronegativity increases.

Answers

Answer:

The correct option is;

The electronegativity increases

Explanation:

The electronegativity is the measure of an atom's ability to attract a shared electron pair. The electronegativity of an atom is dependent on the atom's atomic number and the separation distance between the electrons in the valence shell and the positively charged nucleus such that an increase in the atomic number results in an increase in electronegativity and an increase in the distance between the valence electrons and the nucleus, leads to a decrease in electronegativity.

60 electrons

how many moles is ( 1 x 10^9 ) molecules O2

Answers

Answer:

The answer is

[tex]1.66 \times {10}^{ - 15} \: \: moles[/tex]

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{1 \times {10}^{9} }{6.02 \times {10}^{23} } \\ [/tex]

We have the final answer as

[tex]1.66 \times {10}^{ - 15} \: \: moles[/tex]

A 25-N net force is applied to a rolling cart and produces an acceleration of 5 m/s2 . What is the cart’s mass?

Answers

Answer:

5kg

Explanation:

Given parameters:

Force = 25N

Acceleration  = 5m/s²

Unknown:

Mass of cart  = ?

Solution:

Based on newton's second law of motion;

    Force  = mass x acceleration

 

Now to find the mass;

     Mass  = [tex]\frac{force}{acceleration}[/tex]

   Now insert the parameters and solve;

   Mass = [tex]\frac{25}{5}[/tex]  = 5kg

Which statement best describes John Dalton's use of creativity in his work? He reinterpreted and retested Joseph Proust's results. He used a philosophy to conduct his experiment. He recorded his results as four parts of the atomic theory. He rejected Democritus's idea that matter was composed of atoms.

Answers

Answer: The correct statement is that,

'He reinterpreted and retested Joseph Proust's results'

Explanation:

John Dalton was an English chemist who contributed greatly to the field of Chemistry. He published his theory about atom in 1808.

Dalton was the first person to recognize a workable distinction between the fundamental particle of an element (atom) and that of a compound (molecule). The atomic theory generally summaries the laws of chemical composition which includes:

--> law of constant composition and

---> law of multiple proportions.

John Dalton was being creative in his work by reinterpretation and retesting of Joseph Proust's results. Joseph Proust was a French chemist that first discovered the law of constant composition in 1794. This means that many has started working on the atoms before John Dalton discovery.

From the previous works of Proust, he had studied tin oxides and found that their masses were either 88.1% tin and 11.9% oxygen or 78.7% tin and 21.3% oxygen (these were tin(II) oxide and tin dioxide respectively). Dalton retested and noted from these percentages that 100g of tin will combine either with 13.5g or 27g of oxygen; 13.5 and 27 form a ratio of

Dalton reinterpreted it by finding an atomic theory of matter that could elegantly explain this common pattern in chemistry – in the case of Proust’s tin oxides, one tin atom will combine with either one or two oxygen atoms. I hope this helps, thanks.

It's radio waves because the higher the frequency, the shorter the wavelength. From crest to crest, the wavelength of a radio wave is the shortest. The longest would be ultraviolet light, then visible light, then microwaves! And since radio waves have the highest frequency out of any of them, it has the shortest, look up photoelectron spectroscopy and you'll see! Hope it helps!

how is sonoluminescence similar to what we see in fireworks?​

Answers

Answer:

Explanation:

Sonoluminescence is a phenomenon in which small gas bubbles burst to produce light when intense sound wave is introduced. Thus, it can be said that sound energy is converted to light energy here. This is similar to the process of how fire crackers work except that sonoluminescence occurs in a liquid medium while firecrackers work in solid media. In firecrackers, when the tip is lit with fire, the initial explosion is caused by the expansion of some nitrogen and carbon present in some constituent compounds, this explosion produces heat which causes some other constituent chemicals in the firecracker to quickly react and produce light. Thus, this can also be said to convert sound energy to light energy and are thus similar to what occurs in sonoluminescence.
