Show why Australia gets more UV light than Brazil by
modeling how UV light waves travel through the
atmosphere above each place.
Complete the model by extending each UV light
wave. Use the key to show how the light wave
Interacts with the molecules in the air. If the light
hits a material in the atmosphere, show what
happens to the UV light.
• Use a yellow highlighter to trace the path of energy
• Annotate your model to help show why Australia
gets more UV light than Brazil.
• Tips: Some materials will not be hit by a UV light
wave in your model.

chemistry sucks a**

explanation:

un recipient conține 6,4 moli de gaz. gazul hidrogen reprezintă 25% din totalul kilometrilor din container. în cazul în care presiunea totală este de 1.24 atm ceea ce este

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
