Write a nuclear equation to describe the spontaneous fission of 95 244 Am to form I-134 and Mo-107. Determine how many neutrons
MissTica

<u>Answer:</u> 3 neutrons are produced in the above nuclear reaction.

<u>Explanation:</u>

In a nuclear reaction, the total mass and total atomic number remains the same.

The nuclear reaction for the fission of Americium-244 isotope follows:

^{244}_{95}\textrm{Am}\rightarrow ^{134}_{53}\textrm{I}+^{107}_{42}\textrm{Mo}+Y^1_0\textrm{n}

<u>To calculate Y:</u>

Total mass on reactant side = total mass on product side

\Rightarrow 244=134+107+(Y\times 1)\\\\\Rightarrow Y=244-241=3

Hence, 3 neutrons are produced in the above nuclear reaction.

Which of the following is a mixture <br><br> Water<br><br> Ink<br><br> Alcohol <br><br> Mercury
Zepler [3.9K]
Paper chromatography can be applied to "ink" to determine if it is a pure substance or a "mixture" of pure substances (in which two or more pure substances are combined). Since, tested with paper chromatography, "ink" separates into its constituent pure substances, Ink is a mixture.

I hope this helps.

P.S. Thank you for choosing me as brainliest answer on my last.
