Mass of Li = 237.38 g
<h3>Further explanation</h3>
The mole itself is the number of particles contained in a substance amounting to 6.02.10²³
<h3>Known</h3>
Moles of Li = 34.2
Molar mass(MW) of Li = 6.941 g/mol
then mass of Lithium (Li) :
Answer:
Ketone.
Explanation:
Alkynes experience additions of water catalyzed by acids, across the triple bond in the presence of <u>mercuric ion as a catalyst</u>. Generally, a mixture of mercuric sulfate and aqueous sulfuric acid is used.
Under acidic conditions, mercury is replaced by hydrogen to form a vinyl alcohol, called enol.
<u>Enoles tend to be unstable</u> and isomerize in ketones. This quick equilibrium is known as the keto-enol tautomerism.
Answer:
263.1 is exactly three half-life, so the remaining portion is (1/2 x 1/2 x 1/2) of the original sample. That's 1/8 which is 12.5%
Answer: 7.81 mol HgO (How many moles of mercury(II) oxide, HgO, are needed to produce 125 g of oxygen, O2?)
