This problem is providing us with two reactions between gold (III) chloride and cobalt in order to obtain the two possible cobalt chlorides and gold. Thus, it asks for the most feasible reaction, which is found to be the second one.
<h3>Uses of stoichiometry</h3>
In chemistry, relationships between moles and grams in chemical reactions can be studied via stoichiometry, which is based on proportional factors relating molar masses and mole ratios in chemical equations.
In this case, since we have two reactions and the same initial amount of cobalt, one can calculate the grams of solid gold, with the 1:1 mole ratio of these two in the first reaction and the 3:2 mole ratio in the second one and their atomic masses of 58.933 g/mol and 196.966 g/mol respectively:
![6.087gCo*\frac{1molCo}{58.933gCo}*\frac{1molAu}{1molCo} *\frac{196.966gAu}{1molAu}=20.34gAu\\ \\6.087gCo*\frac{1molCo}{58.933gCo}*\frac{2molAu}{3molCo} *\frac{196.966gAu}{1molAu}=13.56gAu](https://tex.z-dn.net/?f=6.087gCo%2A%5Cfrac%7B1molCo%7D%7B58.933gCo%7D%2A%5Cfrac%7B1molAu%7D%7B1molCo%7D%20%20%2A%5Cfrac%7B196.966gAu%7D%7B1molAu%7D%3D20.34gAu%5C%5C%20%5C%5C6.087gCo%2A%5Cfrac%7B1molCo%7D%7B58.933gCo%7D%2A%5Cfrac%7B2molAu%7D%7B3molCo%7D%20%20%2A%5Cfrac%7B196.966gAu%7D%7B1molAu%7D%3D13.56gAu)
Thus, since the second reaction would produce 13.56 grams of gold, and it is pretty much the same to the recovered amount of 13.572 grams, one concludes the second reaction took place in the experiment.

Answer:
<h2>Acetylene to ethene</h2>
First, acetylene is converted into ethene ( CH2 = CH2 ) using hydrogen gas and Lindlar catalyst. Ethene is an an alkene compound.
<h2>Lindlar catalyst</h2>
Alkynes are converted to alkenes by in the presence of hydrogen gas and lindlar catalyst.
lindlar reagent contains CaCO3, Pd and various forms of sulfur and lead
<h2>Ethene to ethanol</h2>
Then ethanol is prepared from the reaction of ethene with dilute sulfuric acid.
The particles can move around each other because they do not have as strong bonds as solids do.
Answer:
Saturation is the maximum amount of water vapor in the air at an existing temperature and pressure. Air is said to be saturated at 100 percent relative humidity when it contains the maximum amount of moisture possible at that specific temperature. Dew point is the temperature when air reaches 100% relative humidity.
