How van I find the average density of the mixture; then 40 cm3 of gasoline are mixed with 50 cm3 of water. What is the average density of the mixture?
We place some solid Ca3(PO4)2 [Ksp = 5.14x10-33] in water. After reaching equilibrium, what is the pCa (=-log[Ca2+]) of the solution
Describe and define in detail, the term "Bargaining in Good Faith" ?
the enthalpy of formation = 0? Something with standard states? But how do I know what the standard states are
The reaction will be spontaneous at high temperatures because increasing the temperature of a system with a negative change in S eventually results in a positive change in G.
