Answer:
![m=1510gCu=1.51kgCu](https://tex.z-dn.net/?f=m%3D1510gCu%3D1.51kgCu)
Explanation:
Hello,
In this case, considering that the heat due to a change in temperature is given by:
![Q=mCp\Delta T](https://tex.z-dn.net/?f=Q%3DmCp%5CDelta%20T)
Whereas Q accounts for the heat, m for the mass, Cp for the heat capacity and ΔT the change in the temperature, therefore, the mass turns out:
![m=\frac{Q}{Cp\Delta T}=\frac{43.6kJ}{75.0^oC*0.385J/gCu^oC}*\frac{1000J}{1kJ}\\m=1510gCu=1.51kgCu](https://tex.z-dn.net/?f=m%3D%5Cfrac%7BQ%7D%7BCp%5CDelta%20T%7D%3D%5Cfrac%7B43.6kJ%7D%7B75.0%5EoC%2A0.385J%2FgCu%5EoC%7D%2A%5Cfrac%7B1000J%7D%7B1kJ%7D%5C%5Cm%3D1510gCu%3D1.51kgCu)
Best regards.
Acids are sour in taste while Bases are bitter in taste . This is due to the pH that indicates acidity or basicity , and is defined as the hydrogen potential of a solution . ... Acids turn blue litmus paper into red whereas in case of Bases they turn red litmus paper into blue .
