An inert electrode is a substance that is:

A) Sacrificed
B) Degraded
C) Present in the salt bridge
D) none of the above

An inert electrode is a substance, mainly a metal that only serves as the

source of the electrons and doesn't partake in the chemical reaction or

processes.

Inert electrodes are metals which are involved in the transfer of electrons

and chemical reactions involves exchange of ions which it's not involved in

the process.

The statement above about inert electrodes means that the most

appropriate answer is none of the above which is option D.

D) none of the above

Explanation:

An inert electrode is one that only serves as a source of electrons without playing a chemical role.It is normally present to allow current to flow through the cell.Gold and platinum are in most cases used as inert electrodes because they are chemically un-reactive.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
