1. How is the electron configuration of an element determined? How do you know how many valence electrons an element has? (You may use nitrogen as an example
element if it helps you explain.)

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?

What is produced from neutralization of an acid and a base? a. hydronium ions b. citric acid c. salt and water

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.
