Sam used 38 quarts of paint for the outside of the barn and he used 26 quarts for the inside of the barn. How many gallons of paint did sam use to paint the entire barn?

Sam used 16 gallons of paint to paint the entire barn.

Explanation:

1 quart = 0.25 of gallon

38 + 26 = 64

64 / 0.25 = 16

16 gallons.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

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
