Empirical formula is the simplest positive integer ratio of atoms present in a compound.
Ascorbic acid contains carbon , hydrogen and oxygen.
To get the empirical in this case we divide by the smallest value;
3.407/3.406 : 34.53/3.406 : 3.406/3.406
= 1 : 1.33 : 1
this is equivalent to; 1 : 4/3 : 1 , multiplying by 3
we get 3 : 4 : 3
Therefore the empirical formula will be C3H4O3
Depends on where you live but generally speaking it is either June or July
You should see a white precipitate form.
The chemical equation is
AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃
Answer:
Redox reaction and single displacement
Explanation:
This reaction is first of all a redox reaction. A redox reaction is a reaction that involves both oxidation and reduction. Oxidation involves increase in oxidation number while reduction involves decrease in oxidation number.
Copper (Cu) had an oxidation number of "0" as a reactant but had an oxidation number of "2+" in the product [Cu(NO₃)₂] hence oxidation occurred.
Nitrogen (N) had an oxidation number of "5+" in the reactant (HNO₃) but had an oxidation number of "4+" in the product (NO₂) hence reduction also occurred.
Also, from the reaction, it can be deduced that copper (Cu) displaced hydrogen (H) from the nitric acid (HNO₃) solution to form copper (II) nitrate [Cu(NO₃)₂]. It should be noted that copper can displace hydrogen because it is higher than hydrogen in the electrochemical series. Hence, this reaction can also be called a single displacement reaction. A single displacement reaction is a reaction in which an atom of an element replaces another atom in a compound (as seen in the equation given in the question).
