What is the oxidation number for S in the compound SO3?

The oxidation number for S in the compound SO3 is +6

Explanation:

When you add the oxidation numbers in a compound it must be zero unless it is an anion or a cation, we know the oxidation number for O is -2, so in the compound the oxidation number for S is +6

We can check this:

= 3*(-2)= - 6

S= +6

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
