Answer:
100,000
Explanation:
pH of coffee = 5
pH of solution = 10
Concentration of H+ ions between successive pH values are in multiples of 10
Hence, the pH difference :
pH of solution - pH of coffee
(10 - 5) = 5
Hence, difference in H+ ions will be :
10^5 = 10*10*10*10*10 = 100,000 times

Answer:
We can predict or comment about reactivity of elements by taking into consideration their electronic configuration that imparts stability or un-stability to an atom.
Explanation:
Reactivity : It refers to the affinity of a substance to combine with other substance .
Elements are mainly of two types :
In terms of metals or non metals it can be defined as tendency to loose or gain electrons .
- On the basis of it ,we can easily make out or comment about the reactivity of element (metal or non metal ) .Like ,if an element has completely filled outermost shell or we can say have stable electronic configuration then it is already stable .Therefore , it won't react with any other element .
- But, if its outer shell isn't complete then in order to attain stability it will combine or react with other .Hence , we can say it will be quite reactive .
