A sample of 6.81 moles of cesium fluoride is reacted with 8.23 moles of xenon hexafluoride to produce cesium xenon heptafluoride. Using the balanced equation below, predict which is the limiting reactant and the maximum amount in moles of cesium xenon heptafluoride that can be produced. CSF + XeFg → CsXeF7

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

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.

the answer would be a
