Combustion is an exothermic reaction where the reactants are combined with produce CO2 + H2O + . Fill in blanks, please. ALSO...if you give the answer sorry to waste my time you just meer point, or the answer is uploaded in a photo with some link, I report those answers...you are ruining the purpose of and making it almost impossible to find help any longer. You've been warned.

100c is waters boiling point

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

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
