The answer is 17 and a half
Answer:
True.
Explanation:
An exothermic reaction has a positive enthalpy (heat) of reaction. However, it can be negative in some circumstances.
A triple beam balance is used to measure mass
Answer:
![\Delta G =-103.95kJ](https://tex.z-dn.net/?f=%5CDelta%20G%20%3D-103.95kJ)
Explanation:
Hello there!
In this case, since the thermodynamic definition of the Gibbs free energy for a change process is:
![\Delta G =\Delta H-T\Delta S](https://tex.z-dn.net/?f=%5CDelta%20G%20%3D%5CDelta%20H-T%5CDelta%20S)
It is possible to plug in the given H, T and S with consistent units, to obtain the correct G as shown below:
![\Delta G =-111.4kJ-(298K)(-25.0\frac{J}{K}*\frac{1kJ}{1000J} )\\\\\Delta G =-103.95kJ](https://tex.z-dn.net/?f=%5CDelta%20G%20%3D-111.4kJ-%28298K%29%28-25.0%5Cfrac%7BJ%7D%7BK%7D%2A%5Cfrac%7B1kJ%7D%7B1000J%7D%20%29%5C%5C%5C%5C%5CDelta%20G%20%3D-103.95kJ)
Best regards!
Energy from the sun that is neither reflected nor absorbed by the atmosphere passes through the atmosphere to the surface. The ozone layer absorbes most of the ultraviolet radiation, water vapor, and carbon dioxide absorbs infared radiation, clouds, dust, and other gases also absorb energy.
