The reaction of perchloric acid (HCIO4) with lithium hydroxide (KOH) is described by the equation
HCIO4 + KOH → KCIO4 + H20
Suppose 100 mL of perchloric acid is neutralized by exactly 50,0 mL of 1.0 M
of Potassium hydroxide. What is the concentration of the perchloric acid?

What are transitions between a liquid and gas called? identify which way they are transitioning

Which of the following best supports the concept that genetic information is passed on to offspring from both of their parents, not just one?

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
