I Know it sounds strange but i was wondering what your favourite season is and why?
I was born in Autumn and love the way the air goes crisp and it is so lovely to walk when the leaves are changing colour.
I love snow in winter but don't seem to see that much. So i am definately an Autumn Babe

Q1-Find all unit vectors in the plane determined by u=(3,0,1) and v = (1,-1,1) that are perpendicular to the vector w= (1,2,0). Ans. (6/√61,-3/√61,4/√61)
Q2-Use the cross product to find the sine of the angle between the vectors u =(2,3,-6) & v= (2,3,6). Ans.12√13/49
Q5-Distance between the point P and the line through A & B: P(-3,1,2),A(1,1,0),B(0,2,-1). Ans.2√141/√29
Thank u in advance, and if u could provide me ur E-mail address to have future contanct in order to ask questions of MATHEMATICS. Thank u again.

Does this show that hydrogen is still present? Here is the procedure:?

Place pieces of mossy zinc (about 5g) in the erlenmeyer flask. Add 2 ml of copper (II) sulfate solution through the thistle tube. make sure all the connections are air tight. Put 3 test tubes filled with water to collect gas. Provide the test tubes with stopper. Pour 6N HCl through the thistle tube until the zinc is covered. If the reaction becomes sluggish, add more acid. Collect three test tubes of the gas Stopper the test tubes tightly under water and place them in the rack with their mouths downwards. Wash the remaining mossy zinc and return it to the stockroom.
