A student determines the iron(II) content of a solution by first precipitating it as iron(II) hydroxide, and then decomposing the hydroxide to iron(II) oxide by heating.
Identify the formula for potential energy and state what each variable stands for.
a 2.48 l sample of he at 739 torr is mixed with 6.08 l of ar at 325 torr both at 25 degrees c is placed in a 4.80 l
What is the rate law for this reaction. What is the value of the rate constant. How many seconds would it take for the total pressure to be 0.7133 atm
