a point F is at a certain distance from a line AB .Another point P is moving in a plane such that the ratio of it's distance from F and line AB remains constant .find the locus of the point P
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
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...

Explain how a non metal atom becomes negative. Lose an electron, become negative. Bob Pursley isn't at his computer right now but I don't think he would mind if I explained that ADDING an electron to a non-metal makes it become negatively charged. I agree with Dr Bob; ...
explain why oxygen "likes" to form an O^2- ion. O2 is a molecule, not an ion. O2 is stable in the outer electron configuration.
Propose a method for determining the specific heat, Cp, for a metal like sodium which reacts with water. You posted this question several times, and not just today. It has been answered. You will have to fill in the steps yourself. There are other possible methods as well as t...
Propose a method for determining the specific heat, Cp, for a metal like sodium which reacts with water. Allow the sodium to equilibrate in a metal calorimeter filled with inert gas. Measure the equilibrium temperature
the roots of the equation are n=[(-b)+sqrt(b^2-4*a*c)]/2*a n=[(-b)-sqrt(b^2-4*a*c)]/2*a thus, n=[5+sqrt(25+96)]/2*6 n=[5-sqrt(25+96)]/2*6 so,the values of n for this eqn. are n=4/3,-1/2
