Which gas law shows the relationship between pressure and volume?

  A 15.0 mL portion of an acetic acid solution requires 20.0 mL of 0.150 M NaOH solution for neutralization.   Calculate the molarity (M) of the acetic acid solution.  

Predict whether the following would be a strong electrolyte, a weak electrolyte or a non-electrolyte. Note that (s) = solid, (aq) = aqueous (or dissolved in water).   KCl (aq)

On a separate piece of paper complete the table below (you will use this table for the next 2 questions). Then graph y vs. x on graph paper. When done, answer the following statement as true or false: the relationship between y and x is linear.  y x y/x x*y 2 4     4 8     8 16     16 32      

How many moles of NaCl are required to make 250. mL of a 0.500 M NaCl solution?

Give the correctly rounded answer (with the correct number of significant figures or decimal places) to the following calculation: 78.4 / (2.0 x 4.75) =

In this experiment we looked at two general types of reactions:  1) double-replacement (also called metathesis or partner-changing) and 2) redox Answer the following statement with true or false. The reaction below is a redox reaction (if you answer false it is the other type, partner-changing). NaOH (aq) + HCl (aq) → H2O (l) + NaCl (aq){“version”:”1.1″,”math”:”NaOH (aq) + HCl (aq) → H2O (l) + NaCl (aq)”}
