Two buffers are prepared by adding an equal number of moles of formic acid (HCOOH ) and sodium formate (HCOONa ) to enough water to make 1.00 L of solution . Buffer A is prepared using 1.00 mol each of formic acid and sodium formate. Buffer B is prepared by using 0.010 mol of each. (Ka(HCOOH)=1.8*10^ -4 .

Which of these statements explains the difference between nuclear binding energy and the strong nuclear force ?

Find the number of grams of hcl needed to react completely with .50 moles of magnesium.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
