I'm very sure it decreases
Answer:
A campfire is a perfect example of the different kinds of heat transfer. If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.
Explanation:
Answer: 350 kJ/molExplanation:1) <span>δh = -250 kj/mol means that the products of the forward reaction are 250 kJ/mol lower in the potential enery diagram.
2) So, the reverse reaction must compensate the 250 kJ/mol and go upper as much as the activation energy of the forward reaction.
This is:
Ea reverse = Ea forward + | </span><span>
δh |You can see this clearer on the attached graph of an exothermic reaction.
Ea reverse = 100 kJ / mol + | -250 kJ/mol | = 100 kJ/mol + 250 kJ/mol = 350 kJ/mol

Answer:
an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. ... Additionally, the net charge is the same on both sides of the equation.
Explanation:
So what you end up with is you always end up H+ plus OH- yields H2O, because HCl, and NaOH, since they're strong, they fully dissociate. So the Na+, and the Cl - are spectator ions. So with a strong acid and strong base, the net ion equation is always H+ plus OH- yields H2O.
