As we know so far, c = f / λ. This equation comes from a much simpler version of speed = distance/ time. As the λ  (with units "m") can be seen as distance and the frequency (with units "...

Use Brady's Reagent (2,4-DNPH) to test for the presence of the C=O bond in a carbonyl compound. The formation of a yellow precipitate indicates a positive test result. Then determine the melting point ...

The passé simple is used to describe an action that belongs exclusively in the past and was not a habit, as in it happened only once in the past; whereas the imparfait is used to decribe an action that...

To differentiate the quotient of two functions f(x)/g(x) you can use the quotient rule, the formula of which is: (f'(x)*g(x)-f(x)*g'(x))/g²(x)

it is important to remember which...

x = 4.5 

Rearrange the equation, so that like terms are on the same side:

5x - 3x = 2 +7

2x = 9

Then to find x, divide 9 by 2

x = 4...
