2. The lengths of boats in a harbor, in feet, are listed below. 17, 16, 56, 50, 14, 30 12, 33, 82, 16, 10, 52 25, 25, 19, 75, 24, 12 30, 12, 20, 38, 26, 36 33, 24, 18, 26, 40, 40 a. Make a frequency table for the data set. Use 514 as the first class interval. b. Use the ...
use the rational zeros theorem to find all the real zeros of the polynomial function. use the zeros to factor f over the real numbers: f(x)=x^4+2x^3-7x^2-8x+12 I am totally lost, please help?
The second one you had described turned out to be the answer.
Write an equation that represents how dihydrogen phosphate ion (H2PO4-) behaves as an Arrhenius acid. ( Be sure to include the correct charges for ions.)
Write an equation showing that calcium hydroxide acts as an Arrhenius base in water. **(I'm not sure where to start or how to go about this question)
I have come up with a product of HCl_2O^+ + )H^- But that wasn't correct neither was HClO^+ + OH^-
Write the product for the reaction when dichlorine oxide (Cl_2O) reacts with water (the product will have only one equivalent of chlorine in it).
A 19.9mL volume of a hydrochloric acid solution reacts completely with a solid sample of magnesium carbonate, producing 183mL of CO2 that is collected over water at 24.0 degrees C and 738 torr total pressure. The vapor pressure for water at 24.0 degrees C is 22.39 mmHg. What i...
