The nuclear decay equation is
Explanation:
First of all, we look at the periodic table to see what is the atomic number of the two elements involved.
We notice that:
- The atomic number of strontium is 38
- The atomic number of yttrium is 39
This means that in the decay, a neutron from the nucleus of strontium transforms into a proton (because the atomic number, which is the number of protons, increases by 1 unit).
Therefore, this means that the decay involved is a beta-minus decay, in which a neutron converts into a proton emitting an electron (to conserve the charge) alongside an anti-neutrino.
Therefore, the balanced nuclear decay equation is:
where the mass number (94) does not change, since the number of nucleons (protons+neutrons) remains the same.

Answer:
288.2 K
Explanation:
= Volumetric expansion coefficient =
= Initial temperature = 273.1 K
= Final temperature
= Original volume = 150 mL
Change in volume is given by
The temperature of the ethyl alcohol should be 288.2 K to reach 150 mL
