Which of the following complex ions can not demonstrate the cis-trans isomerism? Question 10 options:
[Fe(CO)2(H2O)4]3+
[Fe(CO)3(H2O)3]3+
none of the choices
[Fe(CO)5H2O]3+
[Fe(CO)4(H2O)2]3+

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

hcl + naoh → h2o + nacl

explanation:

hcl + naoh → h2o + nacl   is the reaction that is correctly balanced.

however, pcl3 + h2 → ph3 +3hcl, 2ca+ 3cl2 → cacl3, and c5h12 + 5o2 → 5co2 + 6h2o are not correctly balanced.
