Durin__ the copper lab you make 3.0 grams of copper(II) oxide. For the next step, you add 62.5 mL of 1.0 M HCl in an attempt to make copper(II) chloride. HOW MANY GRAMS OF COPPER (II) CHLORIDE CAN YOU MAKE?

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.

Kp is the equilibrium constant for dissociation of the propionic acid dimer. what is the sign of the slope for a plot of the natural logarithm of kp vs. inverse temperature for this reaction?

How many peaks will be present in a mass spectrum for brcl?
