The color traditionally used to represent magnesium (Mg) is light silver or gray. A top tube in this color would be suitable for drawing a sample for magnesium testing.
Magnesium Nitride is Mg3N2. What I think you do is draw it Mg N Mg N Mg and then draw 8 electrons around each Nitrogen so that Mg shares its 2 electrons with Nitrogen and Nitrogen's Pz electron is bumped down into the Px.
The Squeaky Pop Test Mg and HCl are in a test tube reacting, immediately after placing the Mg inside the test tube, place a second test tube upside down on top of the the first tube When they have finished reacting, place you thumb over the top of the second tube (the one containing the H2 gas). flip it, and light a match (a splint works the same) quickly remove your thumb and place the match/splint over the tube. It should produce a pop (may be a squeek, depending on how well you do it) Copper and hydochloric acid 2 HCl + 2 Cu --> 2 CuCl + H2 (for Cu 1+) 2 HCl + Cu --> CuCl2 + H2 (for Cu 2+) so yes, hydrogen gas is produced for both copper I and copper II
The paper changes colour from red to blue. This is because when you mix MgO with water, you now have Mg(OH)2 solution which is basic and hence changes the colour of red litmus paper to blue.
Fizzing will occur more in test tube A because: i) HCl is a strong acid while CH3COOH is a weak acid ii) HCl completely dissociates into H+ and Cl- ions while CH3COOH wont completely ionise!!!

pale blue
The color of the speckles denote the dosage. Red means 2.5 mg. Blue means 5 mg. Green means 7.5 mg. Orange denotes that it is a 5 mg tablet with less Tylenol.
