P_(4)O_(6) and P_(4)O_(10) are formed by burning P_(4) with O_(2) as: P_(4) + 3O_(2) to P_(4)O_(6) P_(4) + 5O_(2) to P_(4)O_(10) What are the masses of P_(4)O_(6) and P_(4)O_(10) that will be produced by the combustion of 2.0 g of P_(4) in 2.0 g of oxygen leaving no P_(4) and O_(2) ?

Aqueous solution of two compounds M_(1) - O - H and M_(2) - O - H are prepared in two different beakers . If electronegativity of M_(1) = 3.4, M_(2) = 1.2, 0 = 3.5 and H = 2.1 , then the nature of two solution will be respectively

For the reaction A + 2B hArr 2C at equilibrium [C] = 1.4 M, [A]_(o) = 1 M, [B]_(o) = 2 M, [C]_(o) = 3 M . The value of K_(c) is

A biard is at a point P(4m,-1m,5m) and sees two points P_(1) (-1m,-1m,0m) and P_(2)(3m, -1m,-3m) . At time t=0 , it starts flying in a plane of the three positions, with a constant speed of 2m//s in a direction perpendicular to the straight line P_(1)P_(2) till it sees P_(1) & P_(2) collinear at time t. Find the time t.
