The correct answer is D. chemical reaction.
Answer:C
Explanation:
did it
no.mole of H2= mass/RAM
=20/2(2)
=5mol
no.mole of H20=mass/RAM
=5molx2(2+16)mol/g
=180g
Answer:
a
first one i did the test trust me
It may seem sensible to use a very low temperature in order to maximise the yield of ammonia but lower temperatures reduce the rate of reaction.
