This question has multiple parts: Radium-226 undergoes nuclear decay according to the following : 226, 88 Ra->2, 4 He+___ (a) Complete /Balance this nuclear equation. What is the element that completes the equation? (b) What type of radioactive decay is this? (alpha , beta, or gamma ) (c) Radium -226 has a half -life of 1600 years. If a reactor starts with 500.g of radium -226 , how many grams will be left after 4800 years?
(c ) Iodine-131 has a half-life of 8 days. How many grams of I-131 in a 4.0 g sample remain after 24 days? (d) The half-life of 32P, which is used as a label on red blood cells to determine blood volume, is 14.3 days.

(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. Radioactive elements gain stability by single emission, and a successive emission creates a series. Half-life is the half of the amount of life that a radioactive material will continue to exist before it decays completely. 2. When water is mixed with metals, a metal hydroxide is formed and oxygen gas is evolved. The evolution of the oxygen gas from the reaction of metals and water is indicated by the hastened consumption of the splinter. 3. When water is mixed with sodium carbonate, a weak base will be formed. When water is mixed with sodium chloride, a weak base will be formed. 4. In the Winkler Titration Method, sodium thiosulfate is standardized against a known concentration of magnesium iodate. The normality (N) of a solution is always equal to its molarity (M). 5. Dissolved oxygen (DO) refers…
