Explanation: just add the atomic masses on the periodic table together for each atom.
The magnesium dissolves to form magnesium chloride and hydrogen gas is released.
Mg + 2HCl -----> MgCl2 + H2(g).
Characteristic properties are used because the sample size and the shape of the substance does not matter.
Answer:
8.20 % → Percent yield reaction
Explanation:
To find the percent yield of reaction we apply this:
(Produced yield / Theoretical yield) . 100 = %
Produced yield = 112.9 g
Theoretical yield = 1375.5 g
We replace → (112.9g / 1375.5 g) . 100
8.20 % → Percent yield reaction
The two molecular characteristics of substances that typically form liquid cyrstals and there phases are long, cylindrical shape and between molecules & strong intermolecular forces exist
All these enables different application of liquid crystals
