    In a solution of 0.10 M H2SO4, the ions present in order of decreasing order.

    Homework Statement The answer is [ H3O+ ] > [HSO4-]>[SO4-2]>[OH-], but I do not understand how they got it? Homework Equations The Attempt at a Solution First I tried to put H2SO4 into water and got HSO4-. Then I tried to make an ice table, but it didn't work out since Ka for...

    Equations of Slope: X & Y Defining Equation

    What is the defining equation of the concept of slope? I thought it could be rise / run = m or Y2-Y1 / X2-X1 = m but then the next question asks to give the two common forms of the mathematical equation for slope involving X and Y? So would that not be those two equations?

    What Is the Asymptote of y = 2^(x+3) + 4?

    I changed the equation into log form. y = 2^(x+3) + 4 log[SIZE="1"]2y = (x+3)+4 So does that not mean that y can't equal negative 4 since logs can't have a negative?

    What Is the Asymptote of y = 2^(x+3) + 4?

    Oh I'm sorry, you are right the answer is 4, I confused the answer I got which was -4 with the real answer. Yeah what I don't get is why it is 4, I got -4. It's a multiple choice question: A. y = 4 B. x = 3 C. x = -3 D. y = -4
