Answer:
Organic chemistry
Explanation:
Organic material like alcohols and esters are composed mostly of carbon structures, hence the branch is referred to as organic chemistry
Answer: Cs because its further to the right on the table, meaning its more reactive.
Explanation:
I believe c is the right answer.
No, x-rays do not travel slower than infrared radiation or even the opposite. Both are travelling in vacuum therefore they travel at same speed. They differ in the frequency of the electromagnetic waves.
Answer:
d. 127 g/mol.
Explanation:
Hello!
In this case, since we have the amount of molecules of this this compound, we are able to compute the moles out there by using the Avogadro's number:

Which correspond to the moles of X2. Then, by using the mass we are able to compute the molar mass of X2:

It means that the atomic mass of X halves the molar mass of X2, which is then d. 127 g/mol.
Best regards!
