50.0 kg of N2 (g) and 10.0 kg of H2(g) are mixed to produce NH3 (g).Calculate the NH3 (g) formed. Identify the limiting reagent in the production of NH3 in the situation
By suspending a mass of 0.50 kg, a spring is stretched by 8.20 m. If a mass of 0.25 kg is suspended, then its period of oscillation will be :(Take g = 10 ms^-2 )
