A slab of stone of 0.36 m and thickness 10cm is exposed on the lower surface to steam at 100°c. A block of ice at 0°c
rests on the upper surface of the slab. in one hour 4.8 kg of ice is melted. calculate the thermal conductivity of stone.

The answer is the first option just took the test

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.

The answer is 3.
