At constant pressure, 100j heat energy has been delivered to 8 gm of oxygen. what is the change of internal energy? how much work has been done by the gas? (moler heat capacity of oxygen at constant pressure, cp=29.1 j. mol-1.k-1. r=8.314 j. mol-1.k-1.)
can't solve that there any information missing? : / in advance.

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?
