Answer:

Explanation:

On the reactant side, XeO3 is a strong oxidizing agent. It can be a solid or gas. Most likely it is in a solid state.

H+ and Br- combine to form HBr which is a weak acid. So H+ and Br- are in an aqueous state.

On the product side, both Br2 and Xe are not very soluble in water. They will be in gaseous state and H2O is water i.e. liquid state.

Using the Bohr model, determine the lowest possible energy, in joules, for the electron in the Li2+ ion.

lyudmila [28]

Answer: E = - 19.611× $10^{-18}$ J

Explanation: The lowest possible energy can be calculated using the formula:

$E_{n} = - Z^{2}.\frac{k}{n^{2}}$

where:

Z is atomic number of the atom;

k is a constant which contains other constants and is 2.179× $10^{-18}$ J

n is a layer;

For the lowest possible, n=1.

Atom of Lithium has atomic number of Z=3

Substituing:

$E_{1} = - 3^{2}.\frac{2.179.10^{-18}}{1}$

$E_{1} =$ $-19.611.10^{-18}$ J

The energy for the electron in the $Li^{+2}$ ion is - 19.611 joules

Help me understand molarity please

Katyanochek1 [597]

Molarity/ molar is a unit of concentration, symbolized by "M". It is the ratio of the number of moles of solute and the volume of solution.

Molarity = Moles of solute ÷ Liters of solution = moles/liter = M
molarity is define as the number of mole of a solute in 1 liter of solution
