A 3 L gas mixture of propane (C_(3)H_(8)) and butane (C_(4)H_(10)) on complete combustion at 25 C produced 10 L CO_(2.) Assuming constant P and T conditions what was volume of butane present in initial mixture?

Equation of the circumcircle of a triangle formed by the lines L_(1)=0,L_(2)=0andL_(3)=0 can be written as L_(1)L_(2)+lamdaL_(2)L_(3)+muL_(3)L_(1)=0 , where lamdaandmu are such that coefficient of x^(2) =coefficient of y^(2) and coefficient of xy=0. If L_(1)L_(2)+lamdaL_(2)L_(3)+muL_(3)L_(1)=0 is such that mu=0andlamda is non-zero, then it represents

Equation of the circumcircle of a triangle formed by the lines L_(1)=0,L_(2)=0andL_(3)=0 can be written as L_(1)L_(2)+lamdaL_(2)L_(3)+muL_(3)L_(1)=0 , where lamdaandmu are such that coefficient of x^(2) =coefficient of y^(2) and coefficient of xy=0. L_(1)L_(2)^(2)+lamdaL_(2)L_(3)^(2)+muL_(1)^(2)=0 represents
