Which of the following options is correct?Consider two engines, one a reversible Carnot engine and the other an irreversible engine. If we operate both engines between the same two heat reservoirs, and both engines draw the same amount of heat from the hot reservoir, then the heat expelled from the irreversible engine into the cold reservoir will beA) greater thanB) less thanC) the same as the heat expelled from the reversible engine into the cold reservoir.

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
