50cm3 of sodium hydroxide solution was titrated against a solution of sulfuric acid. The concentration of the sodium hydroxide solution was 20g/dm3. Work out the concentration of the acid in grams per litre if it took 25cm3 of acid to completely neutralise the alkali. The relative molecular mass of sulfuric acid is 98. (Hint: It may help to write out a balanced symbol equation for the reaction. The chemical formulas of the acid and alkali are shown below.)

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
