Answer:
The molecular formula of benzene = 
Explanation:
% of C = 92.3
Molar mass of C = 12.0107 g/mol
% moles of C = 
= 7.6848
% of H = 7.7
Molar mass of H = 1.00784 g/mol
% moles of H = 
= 7.6401
Taking the simplest ratio for C and H as:
7.6848 : 7.6401
= 1 : 1
The empirical formula is = 
Molecular formulas is the actual number of atoms of each element in the compound while empirical formulas is the simplest or reduced ratio of the elements in the compound.
Thus,
Molecular mass = n × Empirical mass
Where, n is any positive number from 1, 2, 3...
Mass from the Empirical formula = 12+ 1 = 13 g/mol
Molar mass = 78.0 g/mol
So,
Molecular mass = n × Empirical mass
78.0 = n × 13
⇒ n ≅ 6
<u>The molecular formula of benzene = </u>
Answer:
Well they both would say numbers
Explanation:
The reason why is they both speak english
C₆H₁₂O₆ + 6 O₂ ⇒ 6 CO₂ + 6 H₂O
This is an oxidation-reduction reaction, because oxidation numbers of carbon and oxygen atoms are different than before reaction.
(-_-(-_-)-_-)
Answer:
The correct option is;
a. The particles will gain a large amount of kinetic energy
Explanation:
As the water temperature reaches 100°C, which is the boiling point for water at atmospheric pressure, the continued heating is then used to break up the strong inter molecular forces between molecules of the water such that the individual molecules are free to move about and due to the high temperature, have gained considerable amount of kinetic energy for the to rise to appreciable height and to also spread.
The heat which converts water into steam is called latent heat as during the boiling phase, the temperature of the water remains constant.
