You overhear someone say that two objects with the same mass have the same gravitational potential energy Do you agree? Explain.

What energy is it when you flip on a switch on a lamp

In order to complete this lab. you will need to be familiar with some common chemistry terms. complete the chemical change puzzle and list the relevant terms and their meaning below a. rectant b. product c. supernate

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.
