<span>Jose’s grandmother meant by saying that the bread was too dense, that the bread is compact.</span>
Answer: No
Explanation: It's not balanced because four oxygen atoms in H2SO4, whereas there are 5 oxygen atoms in the reactants side. Also, there's more hydrogen atoms on the reactants side.
I hope this helps!
Thermal expansion<span> is the tendency of matter to change in shape, area, and volume in response to a change in temperature, through heat transfer. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases.</span>
The balanced chemical reaction would be:
2SO2 + O2 = 2SO3
We are given the amount of oxygen to be used. We calculate as follows:
3.5 moles O2 ( 2 mol SO3 / 1 mol O2 ) = 7 mol SO3 is produced from the reaction.
Hope this answers the question. Have a nice day.
