No matter whether SO2 is oxidized to SO32- or not, iodine can also be used as a titrant. (You can check it by finding the experimental steps of finding the conc. of SO2 in a wine for F.7 experiment in 2000 old AL- chem...
28x2+5xy-12y2 =(7x-4y)(4x+3y) 2010-06-28 22:39:31 補充: 28x²+5xy-12y² =28x²+21xy-16xy-12y² =7x(4x+3y)-4y(4x+3y) =(7x-4y)(4x+3y) 另外,可用十字相乘法,請參考意見。
If the liquid is X gm , then you heat it up to dryness , the remain weight Y gm is the weight of dissolved solid , X-Y is the volatile dissolved solids .
yes, KE is transferred from high temp. to low temp. obj. until they have same temp. ps: Internal energy=KE+PE 2008-01-01 15:45:41 補充: 點唔明? email問我
When b² - 4ac > 0, the graph y = ax²+bx+c crosses x-axis; When b² - 4ac = 0, the graph y = ax²+bx+c touches x-axis; When b² - 4ac < 0, the graph y = ax²+bx+c does not touch x-axis...
x,y,z are VARIABLES, 每一個會因其他兩個的"轉變"而"改變". Given that: y α x, y α 1/√z Connecting the relationship of x,y,z, we have: y = kx/√z,where k -- a constant(不會變的數字) ...^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^... a) y/x = constant or not ? =================== y...
