Which of these prevents conduction from occurring? A: Equal Masses

B: Different Masses

C: Equal Temperatures

D: Different Temperatures

I feel like it’s D, let me know if I’m wrong and give me the right answer.

If a sample of radioactive isotopes takes 600 minutes to decay from 400 grams to 50 grams, what is the half-life of the isotope?

Benzonitrile (c6h5cn) is reduced to two different products depending on the reducing agent used. treatment with lithium aluminum hydride followed by water forms k, which has a molecular ion in its mass spectrum at 107 and the following ir absorptions: 3373, 3290, 3062, 2920, and 1600 cm-1. treatment with a milder reducing agent forms l, which has a molecular ion in its mass spectrum at 106 and the following ir absorptions: 3086, 2850, 2820, 2736, 1703, and 1600 cm-1. l shows fragments in its mass spectrum at m/z = 105 and 77. propose structures for k and l and choose an explanation for how this could be concluded.

Food can lose electrons to air. this loss of electrons can create free radicals that destroy chemical bonds, hence spoiling the food. which term describes this process?
