Answer:
This concentrations represents 9.71 x 10¹⁹ nitrate ions per litre of drinking water.
Explanation:
Nitrate: NO₃⁻
MW = 62.00 g/mol
1 mol = 6.022 x 10²³
62 g NO₃⁻ ____________ 6.022 x 10²³ ions
10 x 10⁻³ g NO₃⁻ _________ x
x = 9.71 x 10¹⁹ ions
This concentrations represents 9.71 x 10¹⁹ nitrate ions per litre of drinking water.
Kinetic energy of an object is directly connected to the speed object. Like a toy car being used on a table, the toy car will speed up which means the kinetic energy of that toy car will also increase
The electrostatic potential is the work done to remove the charge. The molecule showing the potential map shows that it is HI.
<h3>What is electronegativity?</h3>
Electronegativity is the elemental property to attract the electron toward the atom and is affected by atomic number and the atomic radius. The map shows that the molecule is made of two different atoms and has linear geometry.
Due to the linear geometry, the molecule cannot be Br₂ and SO₃ as they are nonpolar and nonlinear respectively. Similarly, BrF and ICl can be eliminated as they are interhalogen compounds. In the HI molecule, the hydrogen atom is a cation and the iodine atom is an anion that has high electronegativity differences.
Therefore, HI is the molecule depicted in the potential map.
