Answer: The percent yield of lithium chloride if a reaction starts with 20.0 g lithium hydroxide and yields 6.00 g lithium chloride is 17.2 %
Explanation:
The balanced chemical reaction is
To calculate the moles, we use the equation:
a) moles of
b) moles of
According to stoichiometry :
1 mole of produces = 1 mole of
Thus 0.83 moles of produce= of
Mass of
The theoretical yield of = 34.9 g
The experimental yield of ethanol = 6.00 g
Now we have to calculate the percent yield of ethanol.
Therefore, the percent yield is, 17.2 %
Answer:
Hyoid bone adapted for roaring or B.
Explanation:
Physiological basically means physical. So a physical adaptation would be B.
The average speed is 160 meters a minute.
Sodium is a metal that belongs to group 1 of the periodic table.
<h3>What is my favorite element?</h3>
My favorite element is sodium. Sodium is found in group one of the periodic table. The element is univalent and also forms univalent positive ions. Like every other metal, sodium is able to react with dilute acids to liberate hydrogen gas.
Sodium is a light metal and is known to react with mercury to form the sodium mercury amalgam which is obtained during the electrolysis of sodium chloride. All of the compounds that are formed by sodium are ionic in nature. However the hydrides of sodium are unstable.
Sodium is highly reactive thus it must not be exposed to air since it could ignite spontaneously in air. As such, sodium must be stored under paraffin oil. All the compounds of sodium are ionic in nature.
