Thermochemical modeling energy change project Step 4: Model the energy change in the reaction. a) Create an energy graph that illustrates the energy change in the reaction.
b) Construct your graph on a blank sheet of paper. Be sure to label the axes, provide a title, and
identify the reactants and products on the graph.
Step 5: Explain the energy change in the reaction.
a) Create a new blank document. Type your name at the top.
b) Write a few paragraphs describing the chemical reaction and explaining the energy change in
the reaction. Your document should:
i. identify the reactants and products.
ii. describe the change in energy that occurs as bonds are broken and formed.
iii.
iv.
identify how the potential energy of the reactants compares to the potential energy of
the products.
state and explain the net change in enthalpy.
identify whether the reaction is endothermic or exothermic.
explain how energy is conserved between the reaction and the surrounding
environment.

1. explain hydrogen peroxide, h 2 o 2 properties and decomposition reaction. 2. describe how each of the following natural cycles plays a part in earth’s climate system. (a) the water cycle (b) the carbon cycle

How many moles are contained in 5.6 l of h2 at stp

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
