The amount of heat energy required to change the temperature of 12g of gold from 45°C to 15°C is -47 J. What is the specific heat capacity of gold?

Afraidsugar lol it’s the third one

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
