Given the fictitious chemical equation below 2 cups of tea 1 tablespoon of dry tea + 2 cups of water what is the appropriate stoichiometric factor relating the two "reactants"?
calculate the molar ratios from balanced equations

Explanation:

It is known that for each one tablespoon of dry tea we need 2 cups of water if we want to make two cups of tea.

As 1 cup has 16 tablespoons.

Hence, number of tablespoons present in two cups of water will be as follows.

                    1 cup contains 16 tablespoons

                    2 cups will contain = 2 × 16

                                                     = 32 tablespoons

Therefore, the stoichiometry is 1 : 32.

Thus, we can conclude that the molar ratios from balanced equations is 1 :32.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
