Answer:
The attached figure shows the structure of dimethyl terephthalate.
Explanation:
Dimethyl terephthalate is a compound whose formula is C6H4 (COOCH3) 2. It is a diester produced from terephthalic acid and methanol. It is characterized by being a white solid. Another method for the preparation is from p-xylene and methanol, which is characterized by having an oxidation and an esterification.
Answer:
2.1
Explanation:
Calculation of moles of
Mass of copper = 5.3 g
Molar mass of copper = 315.46 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of = 0.0168 moles
According to the reaction,
1 mole of react with 1 mole of
0.0168 moles of react with 0.0168 moles of
Moles of = 0.0168 moles
Molar mass of = 126.07 g/mol
Thus,
<u>Mass = Moles * Molar mass = 0.0168 moles * 126.07 g/mol = 2.1 g</u>
<u>Answer - 2.1</u>
The given thermochemical reaction is between hydrogen gas and chlorine gas to form hydrogen chloride.
This can be represented as:
Δ
=-184.6 kJ/mol
So when two moles of HCl is formed, 184.6 kJ of energy is released.
Calculating the heat released when 3.18 mol HCl (g) is formed in the reaction:
Therefore, 293.5 kJ of heat is released when 3.18 mol HCl is formed in the reaction between hydrogen and chlorine.
