Which of the following nuclides will likely undergo a beta emission for its dominant radioactive decay mode? a) yttrium-76
b) tin-105
c) cesium-120
d) barium-146

barium-146

Explanation:

Beta emission is said to occur when a neutron is converted to a proton, an electron and a neutrino. Beta emission leads to a decrease in the Neutron/Proton ratio.

Beta emission is common for heavier nuclei having a large number of neutrons. Barium-146 has 90 neutrons, hence it is more likely to undergo beta emission than other nuclides stated among the options.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

you gotta add the following molecules so we can give u an answer

explanation:
