The Universe is surely a vast, infinite place with an infinite number of forms of matter. The Universe is the house for all that is large and unseen (except with the aid of a telescope) as well as small and unseen (except with the aid of a microscope). With that said, please collect data on three objects found in the universe. For example, you can describe a certain planet, certain building, or certain animal; however, the object should be considered "extreme" in a large or small sense. (An example that you cannot use specifically would be Mount Everest - which is known for its extreme height.) In a blog post, please post the name of each object as well as the reported measurements of the objects. Also, include the link or source of the reported measurements.
If a temperature increase from 11.0degree C to 20.0degrees C doubles the rate constant for a reaction, what is the value of the activation barrier for the reaction

what a friedel crafts acylationmechanism would look like using acetic anhydride as the source of the acyl
The second order reaction for the breakdown of nitric oxide to its elements has the rate constants of 0.0796 L/mol-s at 737 C and 0.0815 L/mol-s at 947 C. What is the activation energy of this reaction?
Salicyclic acid forms a polymeric byproduct as a result of this reaction. It is a small percentage of the final product mixture, but it can be visualized via TLC (the small spot just above the aspirin). Provide a balanced chemical equation for the..
A radio station broadcasts at 99.5MHz. Another radio station broadcasts at 720 kHz. Calculate and compare the wavelengths and energies of the photons emitted by these two radio stations.
Balance the following reactions. You may have to supplement the reaction with H+, H2O, or OHdepending on the reaction conditions
Just based on the orbital occupancy of electrons, is it justifiable to distinguish between the transition and inner transition elements. Should we consider any other factors
Learning Goal: To apply the ideal gas law to problems involving temperature, pressure, volume, and moles of a gas.The four properties of gases (pressure P, volume V, temperature T, and moles of gas n) are related by a single expression known as the i..
In the near future, the college will attempt to reduce the cost of chemicals used in campus laboratories. One option suggests the chemistry department use household chemicals instead of expensive laboratory grade materials were ever possible.
The specimen was found to have a ratio of 14C/12C 0.795 times that found in current living plants. What would be the estimated age of the fossil remains? The half-life for carbon -14 is 5720 years.
