Nuclear Chemistry

10D1) Alpha, Beta, and gamma radiation are all totally different. Alpha radiation is radiation that is made up of Alpha particles. Each particle in it contains 2 protons and 2 neutrons and it has a 2+ charge. On the other hand, Beta radiation consists of fast moving electons called beta particles. Each particle contains a 1- charge. The third one, Gamma radiation has no mass and no charge that account for most of the energy loss in nuclear fission.
10D2)Fission is the joining of atoms of diffent elements, while fission is the splitting of atoms.
10D5) Nucleur energy is the energy that is created when the atoms are apart or split. The reactions change in an atom's nucleus. It is used typically in bombing and destruction. During the process mass gets converted into energy. It is used to split in nuclear fission. You can use it for enviromental saftey, clean water, and reduces the dependence of fossil fuels. For peaceful things you can use it to improve food availibility and quality and you can also you it for the treatment of cancer, or radiotheraphy. To conclude, nuclear energy has enormous benefits but, its up to humans to use it safely, and for peaceful purposes.   
 

The Recycling Factory

Dear Mr.Smith,
There is something wrong in the dump truck. You need to seperate the four materials in it Alumimim, soda cans, steel cans, milk jugs, soda bottles. Here's a way to seperate them.To seperate the four materials, I would take the net and put the same materials in one net. I would use the convayor belt to put everything on it, so that the magnet can attract each material closer, exposing the material. You can use the magnet to caputre the steel. Then you would be left with alumimum soda cans. milk jigs, and soda bottles. Next, I will pour all of them in water and see which one will float. Milk jugs will float since the density is less thank water. Then I only have to seperate aluminum soda cans and soda bottles. Next, I would pour both of then in to the concentrated sugar water and see which one will float. Concetrad sugar water has a density of 1.5 g/cm3. So soda bottles will float because the density of it is less than the concentrated sugar water. So all I am left with in the net is the aluminum soda cans.

Why Chemistry the most important science

Everything you do involoves Chemistry.Chemistry involves chemical, compunds, matter, and compostion of objects. Without chemistry you wouldn't be able to cook or clean because in chemistry you use chemicals to cook and clean, also it explains how food changes throughout time. Units of measurements are related to chemistry. You use these measurements when cooking. For example, if you needed to put 1L of oil in your food, you can measure it in a graduated cylinder and put the exact amount in. One of the most important thing we use chemistry in is breathing.Plants make oxygen through photosynthesis using the carbon dioxide that we exhale.
