Electrons and positrons are produced by the nuclear transformations of protons and neutrons known as beta decay. (a) If a proton
Julli [10]

Answer: a) if a proton transforms to a neutron, a positron is produced

B) when an neutron transforms into a proton, an electron is produced

Explanation:

The both are nuclear decay processes which produce a neutrino and tremendous energy. The conversion of protons to neutrons is an energetically difficult process. However, the conversion of neutrons to electrons is commonly called beta decay in nuclear physics.

How many moles are found in a 100.0 g sample of CuF2?
labwork [276]
You can solve this by dividing the mass by the molar mass. The molar mass of CuF2 is about 101.5 g/mol. Therefore there are 100.0/101.5 = 0.985 mol.
