    Chemistry: Post your doubts here!

    we need to know the amount of zinc that was used. To do that we have to subtract the total zinc from that which remained in excess. Thus B-D Do you get it? If we do B-A we will only subtract the weight of empty test tube and that will only give us the mass of zinc we took initially and is not...

    calculate the Mr of NAN3 ... caculate the moles of NaN3 in 50 g of NaN3 by 50/Mr use the ratio method to calculate the moles of N2 produced if 2 mole of NaN3 produces 3 moles of N2 then how many moles will (calculated moles) produce? calculate the volume using the molar gas volume: moles * 24...

    maximum possible I2 is possible when the potentiometer is set at its highest resistance value such that no current passes through the potentiometer... ALL the current of the circuit is passing through the fixed resistor as I2. The least I2 is when the potentiometer is set at its least value...

    for reaction 1: Kc = [X2Y]^2 / ( [X2]^2 . [Y2] ) for reaction 2: Kc = ( [X2] . [Y2]^1/2 ) / [X2Y] If you look closely u will see that Kc for 2 is reciprocal of underroot of Kc for 1. The numerator for Kc 1 is the denominator for Kc2 and vice versa. then power on every substance of Kc1 is twice...
