Which answer is an isotope of 40/20x? <br><br> Question Pictured here:

Nesterboy [21]

An isotope of ₂₀⁴⁰X ⇒₂₀⁴⁴X

<h3>Further explanation </h3>

The elements in nature have several types of isotopes

Isotopes are atoms that have the same number of protons and a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

In the following element notation,

$\large {{{A} \atop {Z}} \right X}$

X = symbol of elemental atom

A = mass number

= number of protons + number of neutrons

Z = atomic number

= number of protons = number of electrons, on neutral elements

For symbol of isotope X :

₂₀X⁴⁰ : atomic number = 20, mass number = 40

A. ₄₀²⁰X : atomic number = 40, mass number = 20, neutrons=20

B. ₂₀⁴⁰X²⁺ : atomic number = 20, mass number = 40, neutrons=20

C. ₂₁⁴⁰X : atomic number = 21, mass number = 40, neutrons=19

D. ₂₀⁴⁴X : atomic number = 20, mass number = 44, neutrons=22

Convert 0.900 atm of pressure to its equivalent in millimeters of mercury. express the pressure numerically in millimeters of me

Angelina_Jolie [31]

1 atm = 760 mm Hg

Where 760 mm is the height of Mercury for 1 atm.

For 0.900 atm,

Height of mercury = 0.900*760 = 684 mm Hg

(b) Briefly explain how the presence of charged ions in ionic solids such as NaCl(s) helps to explain why NaCl(s) is a soluble i

bonufazy [111]

Answer:

-The stronger electrostatic forces of attraction between the oppositely charged ions causes the Sodium chloride to break apart until it completely dissolves in the water.

Explanation:

-Sodium Chloride has positively charged sodium ions, $Na^+$ and negatively charged chloride ions, $Cl^-$ .

-Water on the other hand has positively charged Hydrogen ions, $H^+$ and negatively charged Oxygen ions, $O^{2-}$ due to the difference in electroneganivity.

-When dissolved in water, the positively charged sodium ions will attract the partially negatively charged oxygen ions. The negatively charged chloride ions will be attracted to the positively charged hydrogen ions in the reaction as below:

$NaCl+H_2O->NaOH+HCL\\\\Na^++Cl^-+H_2O->Na^++(OH)^-+H^++Cl^-$
