Answer:
Never leave an open flame unattended
Explanation: if an open flame is left unattended it can cause a fire outbreak so we have to watch it at all times to prevent the fire outbreak
What happens to temperature as a substance melts and heat energy is used to break the connections between molecules, until all melting is complete?.
Answer : Stays the same
<span><span>1) Calculate the total number of nucleons (protons and neutrons) in the nuclide
<span>--> If the number of nucleons is even, there is a good chance it is stable.
</span></span><span><span>
2) Are there a magic number of protons or neutrons?
</span>--> 2,8,20,28,50,82,114 (protons), 126 (neutrons), 184 (neutrons) are particularly stable in nuclei.
</span><span>
3) Calculate the N/Z ratio.
<span>--> Use the belt of stability (Figure 1) to determine the best way to get from an unstable nucleus to a stable nucleus</span></span></span>
