Answer:
15.2 mL
Explanation:
First we calculate the volume of the copper
when this volume of copper is added to the water, the water level will rise by the level of the volume of copper. So the final volume is:
14.6 mL + 0.5580 mL = 15.158 mL
Since the measuring cylinder is graduated to one decimal place , we can round this up to 15.2 mL
The correct answer is C) due to:
at pH 7 alanine molecule lose one proton from its carboxylic acid group and this proton is added to its amino group
This structure is called Zwitter ion (which contain equal number of positive and negative charges)<span />
