Answer:
Explanation:
Hello there!
In this case, since the reaction for the formation of ammonia is:
We can evidence the 1:2 mole ratio of nitrogen gas to ammonia; therefore, the appropriate stoichiometric setup for the calculation of the moles of the latter turns out to be:
And the result is:
Best regards!
Answer:
Option D ()
Explanation:
Acids react with metal to form salt and hydrogen gas.
Metals which are more reactive than hydrogen evolve hydrogen gas on reaction with acid.
For example:
Magnesium reacts with hydrogen chloride to form magnesium chloride and hydrogen.
2HCl(aq) + Mg(s) → MgCl2(aq) + H2(g)
Al and Zn are more reactive than hydrogen, therefore, these metals evolve hydrogen gas on reaction with acid.
reacts with HCl to form NaCl and nitric oxide.
reacts with HCl to form potassium chloride, carbon dioxide and water.
As reaction of does not evolve any gas, therefore, the correct option is D.
