How can I use an infrared spectrum with a mass spectrum to identify an unknown compound?

You’ll need to use both spectrums to pick out information and piece them together to identify the compound, similar to a puzzle. First, you could use the infrared spectrum to identify which functional groups...

A curve has equation y = 20x - x^2 - 2x^3 . The curve has a stationary point at the point M where x = −2. Find the x- coordinate of the other stationary point of the curve

A stationary point on a curve is when the differential of the equation of the curve = 0. In other words when dy/dx = 0Take the equation in the question: y = 20x - x 2 - 2x 3 A simple rule to find the differe...

Explain how an acceleration-displacement graph could be used to determine the frequency of oscillation of a metal plate.

Acceleration (A)= Angular Velocity 2 (w 2 ) Displacement (x)Angular Displacement= 2pi Frequency (f)Gradient= A/x = w 2 = [2pi*f] 2 Rearrange the equation to get - f= (sqrt)gradient/ 2pi

Find the equation of the line through the following points: (-2, -3) and (1, 5)

Note the formula: y - y 1 = m(x - x 1 )x, y, x 1, y 1 refer to the values of your given coordinates. 'm' symbolises the gradient of the line you are asked to findRearrange the formula to make 'm' the subject...
