What a value of 3.5 in equilibrium tells us about a reaction
What is products are favored
100
A solution has a pOH of 9.5 - acid, base, or neutral?

200
What is the name of the group on the periodic table that has a positive 2 charge?
What is alkaline earth metals
200

What is 14
300
This type of solution can only be made by heating up the solution and then allowing it to cool.
What is supersaturated
300
the term defined as the amount of energy required to change solids into liquids.
What is heat of fusion

400
Which element on the periodic table has the highest electronegativity value?
What is Fluorine
400
Explain the enthalpy and entropy of sublimation
What is enthalpy is endothermic and entropy is increasing
400
The calculated value that tells whether a reaction is favorable or not.
What is Gibb's
400
At equilibrium, a solution with an equilibrium value of .435 is pink. The solution is cooled and turns blue. The endothermic side of the reaction is represented by this color.
What is pink
400
Explain the process of titration of an acid to neutralization
Add an indicator to an amount of acid. It will be clear. Add base drop by drop until a pink color remains. Then add acid to get the solution clear again. One drop of base should turn the solution back pink. then and only then are you certain to be at the endpoint.
500
The name of the element from the periodic table with an outer electron configuration of 5D6.
What is Os
500
The properties of solution that is based on the concentration of the solute rather than the type of solute.
What is colligative properties
500
The two driving force of all chemical reactions
What is maximum entropy and minimal enthalpy
