mno−4(aq) cr(oh)3(s)⟶cro2−4(aq) mno2(s) how many hydroxide ions will appear in the balanced equation?

Answers

Answer 1

The reaction of MnO4- and Cr(OH)3 to produce CrO42- and MnO2 has the following balanced equation:

3CrO42-(aq) + 2MnO2(s) + 6OH-(aq) = 2MnO4-(aq) + 3Cr(OH)3(s)

Six hydroxide ions (OH-) will show up on the reaction's product side, according to the balanced equation. This is due to the fact that each Cr(OH)3 molecule provides two hydroxide ions to the process, which requires three molecules of Cr(OH)3 to react with two molecules of MnO4-. As a result, the reaction produces a total of 6 hydroxide ions (2 x 3).

Thus, the balanced equation demonstrates that the reaction of 2MnO4-(aq) and 3Cr(OH)3(s) to form 3CrO42-(aq) and 2MnO2(s) results in the production of six hydroxide ions.

Explain how you can convert from the number of representative particles of a substance to moles of that substance.

Answers

Answer:

the number of representative contain in 1 mol of a substance equals to 6.o2x10^23 particles.

Number of representative particles of a substance can be converted to moles of that substance by multiplying it by Avogadro's number as 1 mole=6.023 ×10²³.

What is Avogadro's number?

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number

What is an element ?

A chemical element is a species of atoms, including the pure substance made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.

They can be identified by their particular atomic number. The periodic table groups the elements according to their atomic number and draws attention to those with related qualities.

The most vital ingredient for life is carbon. Life as we know it would not exist without this element. You'll see that carbon is the main component of the chemicals required for life.
