When a solution of sodium hydroxide is mixed with iron (II) chloride, a green precipitate is formed. What is the balanced equation for that reaction? Question 24 options: FeCl2(aq) + NaOH(aq) → Fe(OH)2(s) + NaCl(aq) Fe2Cl(aq) + NaOH(aq) → Fe2OH(aq) + NaCl(s)
Fe2Cl(aq) + NaOH(aq) → Fe2OH(aq) + NaCl(aq)
FeCl2(aq) + 2 NaOH(aq) → Fe(OH)2(s) + 2 NaCl(aq)

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3

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.

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. p k a1 p k a2 1.30 6.70 calculate the ph for each of the points in the titration of 50.0 ml of 1.5 m h3po3(aq) 1.5 m h 3 po 3 ( aq ) with 1.5 m koh(aq). 1.5 m koh ( aq ) .
