The half-life is constant for the reaction aA =>bB , which is: 

Which of the following is a balanced molecular equation describing the titration of a weak acid with a strong base? 

How can you find the oxidation number of an ion?

The student plotted the experimental kinetics data  as 1/[A] versus time and obtained a straight line graph for the hypothetical reaction aA =>bB.  The y-intercept of the line  of the line must equal to:
