According to ideal gas equation [(p1*v1)\t1]=[(p2*v2)/t2] thus, [(740*410)/300]=[(760*V)/273] so,by solving the above eqn. we get V=363.28 ml

all these can be solved by using the formula a^2-b^2=(a+b)*(a-b) (1)---> ans. is (2x+4)*(2) (2)---> ans. is (5x+4)*(-3x-4) (3)---> ans. is (3x+6)*(5x-2)

In 500cmcube of alcohol solution the percentage of alcohol by volume is 80%. Find the volume of water that must be added to the solution so that the ratio of the volume of alcohol to that of water becomes 5:2? Please some one give me answer
chemistry.
a quantity of 25 ml of a solution containing both Fe2+ and Fe3+ ions is titrated with 23 ml of .02 M KMnO4 solution. as a result all the Fe2+ ions are oxidised to Fe3+ ions. Next the solution is treated with Zn metal to convert all Fe3+ ions to Fe2+ ions. Finally, the solution...
