<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:

^{234.043}_{92}\textrm{U}\rightarrow ^{137.159}_{54}\textrm{Xe}+^{A}_{38}\textrm{Sr}+3^{1.0087}_0\textrm{n}+180MeV

<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:

^{234.043}_{92}\textrm{U}\rightarrow ^{137.159}_{54}\textrm{Xe}+^{93.858}_{38}\textrm{Sr}+3^{1.0087}_0\textrm{n}+180MeV

Hence, the nuclear fission reaction of U-234.043 is written above.

Define climate and weather. What is climate change? Why is it important to know about climate change?
olga55 [171]

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
