Given the equation C2H6(g) + O2(g) → CO2(g) + H2O(g) (not balanced), determine the number of liters of O2 consumed at STP when 85 grams of C2H6 is burned.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

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
