<h3>First we find out the freezing point:</h3>
→(-23.0)-(0.0_
→-23.0 degrees C
<h3>Calculate target Colligative Molarity:</h3>
→ -23=1.86 * Cm
→ 12.37= Cm.
→i* molality
→i= 1
→12.37= 1*m
→12.37= m
<h3>molality= moles of solute(C2H6O2)/kg of solvent water</h3>
12.37m= moles C2H6O2/ 10.0kg water
123.7= moles of C2H6O2
123.7moles C2H6O2 * 62.26g C2H6O2
<h2>= 7701.56 g of C2H6O2</h2>

<h2>Answer:</h2>
The correct answer is option B which is neutron absorbing material.
<h3>Explanation:</h3>
- In nuclear reactors, uranium absorbs a neutron, broke into two nuclei and releasing 3 more neutrons and energy. These neutrons further absorbed by other uranium atoms.
- Control rods are used to control the fission reaction in nuclear reactors by absorbing neutrons.
- Hence the material used in control rods is neutron absorbing material.
Answer:
I think you would pretty much get the answer wrong.
You won´t get full credit. sorry for your wrong test answer, :(
Explanation:
The correct answer would be copper and mercury do NOT react with hydrochloric acid.
