Answer:

Oxide of manganese, Potassium permanganate, Manganese bromide and manganese oxide.

Explanation:

1. Manganese dioxide

Its chemical formula is $MnO_2$. It is +4 oxidation state. It is a black solid which is fairly stable.

2. Potassium permanganate

Its chemical formula is $KMnO_4$. It is commonly used in the laboratories as oxidizing agent. They appear black in color.

3 Manganese bromide

Its chemical formula is $MnBr_2$

4. Oxides of manganese

Chemical formula is $Mn_3O_4$

The most stable state of Manganese is +2 oxidation state.

When 1 mol of KBr(s) decomposes to its elements, 394 kJ of heat is absorbed. (a) Write a balanced thermochemical equation.
VladimirAG [237]

The balanced thermochemical equation is

KBr ------- K + 1/2 Br2

<h3>What is thermochemical equation? </h3>

A Thermochemical Equation is defined as the balanced stoichiometric chemical equation which includes the enthalpy change, ΔH.

The chemical equation for the decomposition of potassium bromide to its constituent elements bromine ans potassium :

KBr ----- K + Br2

The balanced thermochemical equation of the decomposition of potassium bromide to its constituent elements potassium and bromide as follows

KBr ------- K + 1/2 Br2

As the heat is absorbed in this reaction therefore, heat is positive.

Thus, we concluded that the balanced thermochemical equation is

KBr ------- K + 1/2 Br2

Which of the species below can act as a lewis base? bf3 nf3 oh− alcl3?
IRINA_888 [86]
Among BF₃, NF₃, OH⁻ and ALCl₃ both NF₃ and OH⁻ acts as a lewis base.

Explaination:
According to lewis theory of acid and base, base is a specie which has either lone pair of electrons or is negatively charged. So, in the given compounds Nitrogen trifluoride contain lone pair of electron on nitrogen and Hydroxide contains a negative charge on oxygen. And botha are capable to donate these electrons to a lewis acid (electrophiles).
