Chlorine (Cl) lost electrons to form Cl2, it was oxidized and made the reducing agent.
so the correct answer should be chlorine.
hope this helps :)
Answer: B) The rate of reaction
Explanation: Rate of reaction describes the speed at which the reactants of the reaction are getting converted into the products with respect to time.
The equilibrium explains that how much concentration of reactant is in equilibrium with the product.
Solution concentration is the number of moles of solution divided by volume.
The catalyst is the substance which increases the rate of the reaction which bringing any change in other things.
Explanation:
The given data will be as follows.
7 kg of dimethyl terephthalate + 5 kg of Ethylene glycol = 12 kg of product
Formula for weight average number is as follows.
=
Molecular weight of DMT = 198.21 g/mol
Molecular weight of ET = 62.07 g/mol
Hence, calculate the weight average number as follows.
=
= (115.62 + 25.862) g/mol
= 141.482 g/mol
Since, efficiency is given as 50% = 0.5
0.5 =
=
= 70.741 g/mol
As, =
=
= 24 g
Thus, we can conclude that the amount of given polymer is 24 g.
