<u>Answer:</u> The nuclear fission reaction of U-234.043 is written below.
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given fission reaction:

<u>To calculate A:</u>
Total mass on reactant side = total mass on product side
234.043 = 137.159 + A + 3(1.0087)
A = 93.858
Now, the chemical equation becomes:

Hence, the nuclear fission reaction of U-234.043 is written above.
The molar mass of an element represents how many grams of that specific element are in one mole of that specific element
This is classified as a "Formation Reaction"
Answer:
It's important that we understand how the climate is changing so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures.
Weather is the state of the atmosphere at any given time and place.
Climate is the long-term average of the weather in a given place
The answer is B, distillation.
