Law of Conservation of Mass You are to write a lengthy CER paragraph. Below is an outline/organizer. Your final product should be a well organized paragraph. Your paragraph will probably be about 10-15 sentences. You will need to use data from past activities we have done in class as well as your notes about Lavoisier from Friday. Your paragraph should be below the directions. This is homework if you do not finish in class.

The claim should be highlighted in yellow.

Evidence concerning a physical change should be highlighted in green.

Evidence concerning a chemical change should be highlighted in blue.

Evidence concerning a balanced equation should be highlighted in purple.

Reasoning should be highlighted in red.

You are to make a claim stating if mass is conserved in physical and chemical changes.

You will give 3 pieces of evidence to support your claim.
Explain and give data from one activity showing a physical change
Explain and give data from one activity showing a chemical change
Explain and give one example of a balanced equation

Reasoning- State the Law of conservation of mass, tell who came up with this Law, and how he did that.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
