Jason is mistaken in equating a one-time weather event, such as snow in northern Florida, with climate change. Weather is short-term and local, whereas climate represents long-term regional patterns. An isolated weather occurrence does not contradict the extensive evidence of global climate change.
Jason has confused a singular weather event with the overall climate in his reasoning. The correct statement that explains what is wrong with Jason's reasoning is:
A) Jason has confused the weather for one day with the climate of a region.
Weather refers to short-term atmospheric conditions in a specific area, such as a snowy day in northern Florida. Climate, on the other hand, is the average weather in a region over a long period, typically taken over 30 years. A single instance of snow in a typically warm region does not refute the evidence of global climate change. It's the long-term trends and patterns, not isolated incidents, that indicate climate change. Therefore, the occurrence of snow in northern Florida is simply an irregular weather event and not an indicator of the overall climate or a disproof of global climate change.

Answer: C
Explanation:
B. 39 protons, 30 neutrons, 30 neutrons
C. 39 protons, 30 neutrons, 39 electrons
D. 30 protons, 39, neutrons, 30 electrons
Answer:
D. 30 protons, 39 neutrons, 30 electrons
Explanation:
The atomic number (Z) is the number of protons (p) in the nucleus. Since
Z = 30, p = 30.
In a neutral atom, the number of electrons (e) equals the number of protons. Since p = 30, e = 30.
The mass number (A) is the number of protons plus the number of neutrons (n).
A = p + n
For an atom of zinc-69,
69 = 30 + n Subtract 30 from each side and transpose
n = 39
Zinc has the chemical symbol Zn and the atomic number 30. D. 30 protons, 39, neutrons, 30 electrons
Zinc has the chemical symbol Zn, and its atomic number is 30. This means that every atom of zinc contains 30 protons in its nucleus.
An atom of zinc-69 (Zn-69) is one that contains:
- 30 protons (since zinc has an atomic number of 30).
- 39 neutrons (subtract the atomic number from the mass number: 69 - 30 = 39).
- 30 electrons (in a neutral atom, the number of electrons is equal to the number of protons).
So, the correct option is option d 30 protons, 39 neutrons, 30 electrons.
