When 1500J of energy is lost from a 120 gram object, the temperature decreased from 45
degrees C to 40 degrees C. What is the specific heat of the object?

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

the answer is 75.0%.

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
