Answer:
28.25 F per hour
Explanation:
It has a rather very easy solution. First find the temperature difference between the the initial and final internal temperatures which is 145 - 32 = 113 F. The time span is about 4 hours, divide 113 F by 4 , which is 28.25 F per hour.
Option 4. ratio of electrons to protons
Isotope that has atomic number of 82 is stable. An element that has an atomic number ∠82 more stable except Tc and Pm. Also there is the concept that isotopes consisting a combination of even-even,even-odd,odd-even, and odd-odd are all stable. Many isotopes with no magic numbers of nucleons are stable
What are the statements? A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction
Atomic number of an element is the number of protons present in that element. It is unique for each element. The atomic number of carbon is 6.
