2. A storyboard is a series of panels that shows the visual and verbal components of a video you intend to make. Create a storyboard that explains this phenomenon. It must • be one to two minutes in length.
• demonstrate an understanding of Earth’s rotation and revolution.
• include evidence for these motions.
• include the terms: pattern, rotate (rotation), revolve (revolution), axis, Earth’s orbital plane, and Polaris.

You may use any of the aspects of the models used in class and in the Student Text.

i understand the question fully well but what I dont get is what the story board will look like... a write up?

it is the most commonly accepted one

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
