How many moles of Ba3(PO4)2 will be formed by the reaction of 5 moles of BaCl2 and 3 moles of Na3(PO4).
The reaction between BaCl2 and Na3PO4 is:
3BaCl2 + 2Na3PO4 → Ba3(PO4)2 + 6NaCl
The balanced equation shows that 3 moles of BaCl2 react with 2 moles of Na3PO4 to produce 1 mole of Ba3(PO4)2.
Now, using the mole ratio from the equation:
The number of moles of Ba3(PO4)2 formed is 5 moles.

A bob of mass \(m\) is suspended at a point \(O\) by a light string of length \(l\) and left to perform vertical motion (circular) as shown in the figure. Initially, by applying horizontal velocity \(v_0\) at the point ‘A’, the string becomes slack when the bob reaches at the point ‘D’. The ratio of the kinetic energy of the bob at the points B and C is:
