Answer:
D.HI
Explanation:
because this is the most different
The right answer for the question that is being asked and shown above is that: "d. does not produce energy in nuclear power plants." The model most likely represents a reaction which d. does not produce energy in nuclear power plants<span>

Ionic compounds are compounds composed of a metal as the cation (positive charge) and non-metals as anion (negative charge). Covalent compounds are composed of both non-metals. In this respect, a) water is covalent b) covalent c) ionic d) ionic e) covalent f) ionic.
Gilbert N. Lewis (1875-1946) was an American physical chemist.
His work with heavy water and resources were adapted by Ernest Lawrence in the development of the cyclotron.
SCIENTIFIC CONTRIBUTIONS
Lewis made many contributions to science. He was nominated for the Nobel Prize 41 times, though he was never awarded the prize.
He discovered covalent bonds and electron pairs. He worked with isotope separation, and became the first person to purify a sample of heavy water. The heavy water was later used as projectiles in Lawrence’s 27-inch cyclotron.
He also made contributions in ideas on relativity and acid-base reactions and coined the term “photon” as the smallest unit of light.
A solute rises the boiling point of a solution, in direct relation with the number of particles added to the solution. Sucrose remains a molecule, does not separate into anything. NaCl gives Na+ + Cl-.
<span>Molar mass of sucrose is 12*12+22*1+11*16=144+22+176=342 </span>
<span>105g sucrose is 105/342=0.3moles ---> 0.3 moles of particles (molecules) </span>
<span>Molar mass of NaCl is 23+35.5=58.5 </span>
<span>35 grams of NaCl is 35/58.5=0.598 ----->0.598*2=1.1974 moles of particles (ions, Na+ and Cl-) </span>
<span>So, 35 grams of sodium chloride in 500 grams of water will have a higher boiling point</span>
