A noble metal is a metal that resists oxidation and does not corrode (i.e: rust). Silver and platinum are great examples since they don't rust
Answer:
I. dissolving more solute in an unsaturated solution
Explanation:
A saturated solution is the solution which contains maximum concentration of solute dissolved in solvent.
However, if the solution is being provided with energy (heating) , it will dissolve more heat and the solution that cannot even dissolve more solute after heating is super saturated solution.
<u>Both saturated and supersaturated solutions have maximum of their capacity to dissolve the solute and hence further energy requires energy and these processes are non-spontaneous.</u>
<u>An unsaturated solution can dissolve more solute easily and thus is a spontaneous process.</u>

Answer : Half reaction is defined as the reaction which will be <span>either the oxidation or reduction </span>reaction<span> of particular species in a given redox </span>reaction<span>.
So as per the definition in the reaction of,
</span>
<span>
</span>
<span>
here on left and right side </span>
will get cancelled.
and we will get,
Here,
...this is oxidation reaction as Ba is getting reduced to
by losing 2 electrons.
whereas,on the other hand,
...this is reduction reaction as
is getting reduced to Zn by gaining 2 electrons.
Answer:
C. the relative molecular mass of the compound
Explanation:
Like molecular formulas, empirical formulas are not unique and can describe a number of different chemical structures or isomers. <u>To determine an empirical formula, the relative molecular mass of the composition of its elements</u> can be used to mathematically determine their ratio.
