Write the nuclear reaction equation for the beta decay of Iodine-131

Explanation:

In a beta (minus) decay, a neutron in a nucleus turns into a proton, emitting a fast-moving electron (called beta particle) alongside with an antineutrino.

The general equation for a beta decay is:

(1)

where

X is the original nucleus

Y is the daughter nucleus

e is the electron

is the antineutrino

We observe that:

In this problem, the original nucles that we are considering is iodine-131, which is

where

Z = 53 (atomic number of iodine)

A = 131 (mass number)

Using the rule for the general equation (1), the dauther nucleus must have same mass number (131) and atomic number increased by 1 (54, which corresponds to Xenon, Xe), therefore the equation will be:

i. like it i'm gonna edit it tomorrow

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
