Answer:
1. CBr4
2. C5H12
3. CF4
4. C8H17NH2
Explanation:
1. The boiling point of a molecule depends on its structure. Because the boiling point of molecules of similar size, depends on the differences in functional groups of the molecule.
For example CBr4 have a higher boiling point than other compounds because they have both London dispersion forces and dipole-dipole interactions.
2. Non-polar molecules like C5H12 will have low melting and boiling points, because they are held together by the weak van der Waals forces.
Answer: 55.56 moles of MgO
Explanation:
1 mole = avogadro number
if 6.21x10^25 atoms then molecules of MgO (equal numbers of Mg and O atoms)
= 0.5*6.21x10^25 = 3.105 molecules of MgO
So moles of MgO = 0.5*6.21*10^25/avogadro number = 55.56
Answer:
The answer option which best describes nuclear fission is: C. A nucleus collides with a neutron and splits, releasing energy.
A nuclear reaction can be defined as a type of reaction in which the nucleus of an atom is transformed by either being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive element and accompanied by a release of energy.
