Answer:209.53
Explanation:
Molar concentration=moles/Volume. Volume is given as 750mL which can be converted as 0.75l,so moles of CuBr2 is molar concentration ×Volume= 1.25×0.75=0.9375
Mole =mass of CuBr2/molecular Mass of CuBr2.
Molecular Mass of CuBr2 is 63.5+80×2=223.5(mass number of Cu=63.5 and Br=80).
So mass required= 223.5×0.9375=209.53g
It would be d bc when it’s at its lowest point it means not that much energy and that would be its lowest point which is D

Answer:
The answer is oxygen and silicon
Explanation:
I took the test and it was right
Start the reaction with an excess of methane and only a small amount of chlorine.
When the reaction is over, there will be a small amount of chloromethane and a large excess of methane. These can be easily be separated due to their differing boiling points.
Free Radical halogenation is a substitution reaction in which a hydrogen atom is replaced with a halogen atom, via a free radical reaction mechanism.The halogen radical abstracts the hydrogen from our alkane as the first step. In this phase, we form our side product, in this case HCl. We will then interact with a different halogen molecule to produce a reaction. The halogenated product is produced in this stage, and the halogen radical is also renewed.
