The ph level of a solution measures how acidic or basic the solution is. values between 0 and 7 are considered acidic while values between 7 and 14 are considered basic. the ph is calculated by using the equation ph=−log[h3o+]. the notation [h3o­­­+] represents the concentration of hydronium ions, which is measured in units of moles per liter, m.

what is the ph level of a solution if [h3o+]=3.4×10^−3m?

Raymond just got done jumping at super bounce trampoline center. the total cost of his session was $43.25 . he had to pay a $7 entrance fee and $1.25 for every minute he was on the trampoline. write an equation to determine the number of minutes (t) that raymond was on the trampoline.

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
