A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2H++Na2CO3⟶2Na++H2O+CO2 A volume of 24.13±0.06 mL of HNO3 solution was required for complete reaction with 0.9743±0.0008 g of Na2CO3 , (FM 105.988±0.001 g/mol ). Find the molarity of the HNO3 solution and its absolute uncertainty. {HNO3] = ?M = +/- ? M

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?

According to coulomb's law, how would the electrical force between particles change if the product of their electrical charge increased?
