(4) an atomic number of 17

Every chlorine atom has   \boxed{\left(4\right){\text{ an atomic number of 17}}}

Further explanation:

The <em>smallest particle</em> that is the <em>building block of matter</em> is known as an <em>atom</em>. Most of the space in an atom is empty and its <em>mass </em>is concentrated inside a small region called the <em>nucleus</em>.

Protons, electrons, and neutrons are the three subatomic particles that are present in the atom. Electrons revolve around the nucleus in definite orbits.

An atom is also written as _{\text{Z}}^{\text{A}}{\text{X}}  , where A is the atomic mass or mass number, Z is the atomic number and X is the letter symbol of the element.

Atomic number is equal to the number of protons present in the nucleus of the atom. Atomic mass is the total number of nucleons (protons and neutrons) within the atomic nucleus. It is also known as the mass number.

Isotopes:

Atoms of the same element with <em>same atomic number</em> but <em>different mass numbers</em> are called isotopes. These have the same number of protons but the number of neutrons is different. For example, _{\text{6}}^{{\text{11}}}{\text{C}}  and _{\text{6}}^{{\text{12}}}{\text{C}}  form isotopes of the same element carbon. These have the same atomic numbers (6) but different mass numbers (11 for _{\text{6}}^{{\text{11}}}{\text{C}}  and 12 for _{\text{6}}^{{\text{12}}}{\text{C}} ).

Atomic number of any element is equal to the number of protons in it. But in case of neutral atom, it is also equal to the number of electrons. The atomic number of chlorine is 17 so the number of electrons in it is also 17 and therefore statement (1) is incorrect.

Chlorine exists in different isotopic forms that have different mass numbers so number of neutrons of every chlorine atom cannot always be the same. Therefore statements (2) and (3) are incorrect.

According to the position of chlorine in the periodic table, it is clear that its atomic number is 17. Every element has its own characteristic atomic number that is used to distinguish it from other elements. So every chlorine atom has an atomic number of 17. Therefore statement (4) is correct.

A student sees an absorbance a=1.140 for his solution that has a concentration of c=1.50*10-4 m using 0.50 cm cuvette. what is t
777dan777 [17]

The molar extinction coefficient is 15,200 M^{-1} cm^{-1}.

The formula to be used to calculate molar extinction coefficient is -

A = ξcl, where A represents absorption, ξ refers molar extinction coefficient, c refers to concentration and l represents length.

The given values are in required units, hence, there is no need to convert them. Directly keeping the values in formula to find the value of molar extinction coefficient.

Rewriting the formula as per molar extinction coefficient -

ξ = \frac{A}{cl}

ξ = \frac{1.140}{1.5*10^{-4}*0.5 }

Performing multiplication in denominator to find the value of molar extinction coefficient

ξ = \frac{1.140}{0.000075}  

Performing division to find the value of molar extinction coefficient

ξ = 15,200 M^{-1} cm^{-1}

Hence, the molar extinction coefficient is  15,200 M^{-1} cm^{-1}.

What are fluids? Why are they so called?​
navik [9.2K]

Answer:

<em>Liquids and gases are called fluids because they can be made to flow, or move.</em>

<em> In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.</em><em> </em><em>So</em><em> </em><em>that</em><em> </em><em>they're</em><em> </em><em>called</em><em> </em><em>fluids</em><em>.</em>

What are the functions of ammonia in the solvay process​
enot [183]
The ammonia gas is absorbed in the concentrated brine to produce aqueous sodium chloride and aqueous ammonia. This ammoniation process is exothermic, so energy is released as heat. The ammonia tower eventually needs to be cooled.
