The mass of H2 (in g) which would be obtained from 21g of hydrolith when it reacts with water is________

What is the weight of hydrogen gas (in g) obtained from 42 g of CaH_2 by treatment with water ?

How many grams of H_2 would be produced, if 130 g of zinc reacts with an excess of dilute of H_2SO_4 (Zn-65)

H_(2)O_(2) can be obtained when following reacts with H_(2)SO_(4) except with-

White phosphorus reacts with chlorine and the product hydrolyses In the presence of water, Calculate the mass of HCI obtained by the hydrolysis of the product formed by the reaction of 62 g of white phosphorus with chlorine in the presence of water.

The equivalent mass of a metal is 11.6. when 0.177g of that metal is allowed to react completely with dilute HCl, what will be the volume of H_(2) gas liberated at 12^(@)C and 766mm Hg pressure?

At 986^(@) C the value of equilibrium constant (K_c) for the reaction, CO(g)+H_2O(g)toCO_2(g)+H_2(g) is 0.63At this temperature, 1 mol of H_2O (g) is allowed to react with 3 mol of CO(g). This results in the above equilibrium in which the observed pressure is 2.0 atm. Find the number of moles of H_2 (g) produced at equilibrium and the partial pressure of each gas

A balloon is rising upwards from rest with acceleration (g)/(8) . A stone is dropped from the balloon when it is at height H. Show that the time by which the stone will touch the ground is 2 sqrt((H)/(g)) .

Dinitrogen and dihydrogen react with each other to produce ammonia according to the chemical equation : N_2 (g) + 3H_2 (g) rarr 2NH_3 (g) Calculate the mass of ammonia produced produced if 2.00 xx 10^3 g nitrogen react with 1.00 xx 10^3 g dihydrogen.
