Apiece of zinc of mass 5.00 g is dropped into a beaker containing 250. ml of 0.560 m hydrochloric acid. calculate in joules the work done by the system as a result of the reaction. the atmospheric pressure is 836 torr and the temperature is 23ºc. indicate any assumptions or approximations.

i don,t know so just answer mine

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
