In the reaction, 4 NH3 + 5 O2 → 4 NO + 6 H2O,
when one mole of ammonia and one mole of oxygen are made to react to completion, then
All the oxygen is consumed
1 mole of O2 will react with 4/5 mole of NH3. Hence, all the oxygen is consumed.
If 30mL H2 and 20mL of O2 react to form water, what is left at the end of the reaction?
How many moles of magnesium phosphate, Mg3(PO4)2 will contain 0.25 mole of oxygen atoms?
The decomposition of a certain mass CaCO3 gave 11.2 dm3 of CO2 gas at STP. The mass of KOH required to completely neutralize the gas is
1.520 g of hydroxide of a metal on ignition gave 0.995 g of oxide. The equivalent weight of the metal is
The number of g-atom of oxygen in CO molecules is
500 mL of NH3 contain molecules at S.T.P. How many molecules are present in 100 mL of CO2 at S.T.P.?
An unknown element forms an oxide. What will be the equivalent weight of the element if the oxygen content is 20% by weight?
A metal M of equivalent mass E forms an oxide of molecular formulaMxOy. The atomic mass of the metal is given by the correct equation
Which of the following methods of expressing concentration are independent of temperature?
Pressure is determined as force per unit area of the surface. The S.I unit of pressure, pascal, is as shown below:
1Pa = 1 Nm–2
If mass of air at sea level is 1034g cm-2, calculate the pressure in pascal.
