Answer:

B6Br4

Explanation:

Chemical formula gives a representation of the number of atoms that each element in a compound or molecule. In this question which is asking to give the formula of hexaboron tetrabromide, the hexa means 6 while the tetra means four.

Since the number of atoms of each element is written as a prefix before the main element, this means that the chemical formula of hexaboron tetrabromide will be B6Br4.

O2- is the Lewis ______ in the following reaction

matrenka [14]

$O^{2-}$ is the Lewis base in the following reaction:

$SO_3(g) + O^{2-}(aq)$ → $SO_4^{2-}(aq)$

<h3>What is lewis base? </h3>

Lewis base is a species that donates an electron pair.

In the above-given chemical equation, the $O^{2-}$ is the lewis base which is donating an electron pair to the central atom of $SO_3$ to form $SO_4^{-2}$ .

Hence, $O^{2-}$ is the Lewis base in the following reaction:

$SO_3(g) + O^{2-}(aq)$ → $SO_4^{2-}(aq)$

When hydrated copper(II) sulfate crystals are heated, anhydrous copper(II) sulfate forms. A mass of 12.5 g of hydrated copper(II

pychu [463]

The formula of hydrated copper(II) sulfate is CuSO4.10H2O

<h3>What is the formula of the hydrated copper (ii) sulfate salt?</h3>

The formula of the hydrated copper (ii) sulfate is determined as follows:

Mass of hydrated salt = 12.5 g

Mass of anhydrous salt = 8.0 g

Mass of water = 12.5 - 8 = 4.5 g

mole ratio of water and anhydrous salt is;

4.5/18 : 8.0/159.5

0.562 : 0.05

10 : 1

Water of crystallization (n) = 10.

Therefore, the formula of hydrated copper(II) sulfate is CuSO4.10H2O
