Acid spills are often neutralized with sodium carbonate. For example Na CO2 (s) + H2SO4 (aq) → Na2SO4 (aq) + CO2(g) + H20 (1)
An instructor dropped a 2.50 L bottle of 18.0 M H2SO4 on a cement floor.
How much sodium carbonate would be required to neutralize it?

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
