Earth has approximately 600,000,000 meters of coastline. If we assume this entire length of coastline has sandy beaches 60 meters wide and 20 meters deep, how many cubic meters of sand are on the beaches? Express your answer to the correct number of significant figures.

There are
× 10
cubic meters of sand on the beaches.

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.
