We have learned about balancing chemical equations as well as assigning of state symbols.
Let’s look at some examination questions and my suggested solutions.
Q) Write balanced chemical equations for each of the following reactions. Include the State Symbols.
(a) calcium + chlorine –> calcium chloride
(b) hydrogen + nitrogen –> ammonia
(c) ethane (C2H6) + oxygen –> carbon dioxide + water
My Suggested Answer:
(a) Ca(s) + Cl2(g) –> CaCl2(aq)
(b) 3H2(g) + N2(g) –> 2NH3(g)
(c) 2C2H6(g) + 7O2(g) –> 4CO2(g) + 6H2O(l)
Your answer is correct, balancing in stoichiometri and right in symbolyzing.i think you should be a proffesor in basic concept of chemistry.
And thanks for your couraging emails. its make me survive in these difficult and bad people. hope you will always write more and more simple concept in chemistry for us.
best regards from the biochemist.
