Base your answers to the following questions on the information below. Uranium-238, a solid, is a naturally radioactive element found in the earth's crust. As it decays one of the products is radon-222 which is a gas and is very radioactive. A: Write the equation for the alpha decay of Rn -222. B: The half-life of Radon-222 is 3.82 days. How many grams of a 1.0 gram sample of Rn -222 would remain after 7.64 days? Show table format for work (you may do this on the back if you do not have space). C: Describe the penetrating power of the nuclear particle released during the alpha decay of Uranium-238. Compare it to the penetrating power of other forms of radiation such as beta or gamma radiation.
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
