Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. when samples of these were decomposed the sulfur dioxide produced 3.49g oxygen and 3.50g sulfur, while the sulfur trioxide produced 9.00g oxygen and 6.00g sulfur.

a) calculate the mass of oxygen per gram of sulfur for sulfur dioxide.
b) calculate the mass of oxygen per gram of sulfur for sulfur trioxide.

a. 0.997

b. 1.5

Explanation:

Hello, considering the decomposition chemical reactions:

a.

b.

The produced amounts are enough to know the required proportion, thus:

a. For this case, it is simple as long as the stoichiometric coefficients are 1 for all the involved species in the chemical reaction, thus:

b. In this case, it is not a problem that the stoichiometric coefficient for oxygen is 3/2 yet the amounts remain the same, thus, the ratio:

Best regards.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
