Answer:Pressure of NH3 increases at the rate of 160torr/hr
Explanation:
According to the equation below
N2H4 (g) + H2 (g) ==> 2 NH3 (g)
It shows that 1mol of N2H4 will gives 2mol of NH3
Therefore, if the partial pressure rate of N2H4 is 80torr/hr, the partial pressure of NH3 increases by 2×80=160torr/hr
Mass of barium is 137.327 g/mol. Mass of radium is 226 g/mol.
Hence, radium has more mass therefore it will have the greatest density at STP.
Hope this helps :)
Answer:
matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
