Chemistry
1 answer:
Anna [14]2 years ago
4 0

Mass of KMnO4 required : 31.607 g

<h3>Further explanation </h3>

The reaction equation is the chemical formula of reagents and product substances  

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products  

Reaction

2KMnO₄ → K₂MnO₄ + MnO₂ + O₂

mol of O₂ :

\tt \dfrac{1.6}{16}=0.1

mol ratio KMnO₄ : O₂ = 2 : 1

mol of KMnO₄ :

\tt \dfrac{2}{1}\times 0.1=0.2

mass of KMnO₄ :

MW KMnO₄ : 158,034 g/mol

\tt mass=0.2\times 158,034 =31.607~g

Which of these reactions involves an acid and a covalent base?
Juli2301 [7.4K]
I think the correct answer would be D. The reaction that involves an acid and a covalent base would be the reaction of sulfuric acid and water or H2SO4 + 2H2O → 2H3O+ + SO42– . The acid would be H2SO4 and the covalent base would be H2O since it is being held by covalent bonds and when in solution it will have equal amounts of OH- and H+ ions.
