What is the increase in entropy when 11.2 L of O_(2) are mixed with 11.2 L of H_(2) at STP?

The line l_(1) passing through the point (1,1) and the l_(2), passes through the point (-1,1) If the difference of the slope of lines is 2. Find the locus of the point of intersection of the l_(1) and l_(2)

Consider a regular 10-gon with its vertices on the unit circle. With one vertex fixed, draw straight lines to the other 9 vertices. Call them L_(1), L_(2), ….L_(9) and denote their lengths by l_(1), l_(2)….l_(9) respectively. Then the product l_(1)l_(2)....l_(9) is

Consider a regular 10-gon with its vertices on the unit circle. With one vertex fixed, draw straight lines to the other 9 vertices. Call them L_1 , L_2 ,…, L_9 and denote their lengths by l_1 ,l_2 ,…, l_9 respectively. Then the product l_1 , l_2,...,l_9 is
