You dont have to know the mass of different particles to make predictions about the mass of product made in a chemical reaction. True or False
False
The molar mass of a compound depends on the atomic masses of the elements that make it up. True or False
True
Stored energy associated with the position, shape or condition of an object.
Potential energy
Is this an example of potential energy?
Noo, is Kinetic energy
Thermal energy will transfer from the lower temperature system to the higher? True or False
Falseee
This law states that the total energy of an isolated system remains constant.
Conservation of Energy
A chemical reaction in which the products can react to reform the reactans is called a chemical equilibrium? True or False
False, is a reversible reaction
In what time the chemical equilibrium is reached in this graph.
80 s
In weak acids, hydrogen atoms are bound more tightly, so are more difficult to ionize. True or False
True!
What is the main thing that is needed to neutralize a reaction?
Buffer
