Ammonia can be made by reaction of water with calcium cyanamide CaCN2(s).?

Question

When the equation is properly balanced with the smallest ratio of integer coefficients, which of the following statements are true ?


a) The coefficient of calcium cyanamide is 2

b) The coefficient of water is 3

c) The coefficient of ammonia is two thirds that of water

d) The coefficients of calcium cyanamide and calcium carbonate are both 1.


you must enter all true statements in one lower case group,
in alphabetical order
e.g., if a) b) and e) are true you would enter abe

Answer 1

bcd



Solution:
CaCN2 + 3H2O ---> 2NH3 + CaCO3

Answer 2

IF I've got this right, here's the balanced equation:

CaCN2 + 3 H2O --> CaCO3 + 2 NH3

So, bcd would be the answer.

Answer 3

CaCN2 +3 H2O --->2 NH3 + CaCO3

bcd
