1. the Moon must be in line with the Earth and Sun - New Moon for a solar eclipse and Full Moon for a lunar eclipse.2. the Moon must be at one of its nodes. Most of the time the Moon at New or Full passes above or below the Sun because its orbit is tilted relative to the ecliptic. An eclipse can occur only when it is at a node, in other words crossing the ecliptic.

This energy level is expressed in the form of electron configurations.

Lithium with atomic number 3, then the electron configuration:

Write balanced equations that describe the following reactions. (Use the lowest possible coefficients. Use the pull-down boxes t

Gnesinka [82]

Answer : The balanced chemical reaction will be:

$HBrO_4(aq)+H_2O(l)\rightarrow H_3O^+(aq)+BrO_4^-(aq)$

Explanation:

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

As we know that perbromic acid is considered a strong acid that means it will completely dissociate in water.

The balanced chemical reaction will be:

$HBrO_4(aq)+H_2O(l)\rightarrow H_3O^+(aq)+BrO_4^-(aq)$
