Assume that the age of the Earth is 4.6 billion years. How many half-lives of Rubidium-87 does the age of the Earth represent?
Divide 4.6 billion by 5x1010 which is the half life of Rubidium 87, and you will have your answer.
The attractive force between sodium ions and chloride ions results in an arrangement of ions in repeating units arrangement of ions in repeating units arranged to form what?
I assume you have Chemistry, not my favorite class this year but anyways..The attractive force pulls many ions together into a tightly packed structure. The tight packing of the ions causes any salt, such as sodium chloride, to have a distinctive crystal structure. Crystal structure is your answer.Cool fact.The smallest crystal of table salt that you could see would still have more than a billion billion sodium and chloride ions!Good day
How many houses were destroyed in the US April 2011 tornado outbreak?
There were several major tornado outbreaks in the US in April 2011, but you are most likely referring to the catastrophic outbreak of April 25-28 with most of the damage on April 27. Reliable sources are hard to come by. One article states that approximately 6,200 homes were destroyed in Alabama alone. Alabama suffered about $4.3 billion of the approximately $4.8 billion in damage from the outbreak. If we assume all of these figures are accurate and that the ratio of cost to homes destroyed remains about the same, then we can arrive at a very rough estimate of about 6,900 homes destroyed.
