Answer:
THE EMPIRICAL FORMULA OF THE SUBSTANCE IS C2H5NO
Explanation:
The steps involved in calculating the empirical formula of this substance in shown in the table below:
Element Carbon Hydrogen Nitrogen Oxygen
1. % Composition 40.66 8.53 23.72 27.09
2. Mole ratio =
%mass/ atomic mass 40.66/12 8.53/1 23.72/14 27.09/16
= 3.3883 8.53 1,6943 1.6931
3. Divide by smallest
value (0.6931) 3.3883/1.6931 8.53/1.6931 1.6943/1.6931 1.6931/1.6931
= 2.001 5.038 1.0007 1
4. Whole number ratio 2 5 1 1
The empirical formula = C2H5NO
What are the molecules that are being bonded?
there are <u>4 </u>grams of product produced by the chemical reaction
Answer:
a)
The electro-chemical cell is non spontaneous because is negative
b)
The electro-chemical cell is spontaneous because is positive
Explanation:
a)
Electron change, n = 2
The electro-chemical cell is non spontaneous because is negative
b)
Electron change, n = 2
The electro-chemical cell is spontaneous because is positive
