Divide 4.6 billion by 5x1010 which is the half life of Rubidium 87, and you will have your answer.
Divide 4.6 billion by 1.31x109 which is the half life of Potassium-40 and you will have your answer.
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
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.

Chlorine has no "normal" temperature, it will assume whatever the ambient temperature is.
Divide 4.6 billion by 1.31x109 which is the half life of Potassium-40 and you will have your answer.
1000 thousands = 1 million 1000 million = 1 billion 1000 billion = 1 trillion This is what I assume to be correct. But then again does it really matter how many billion are there in a trillion.
Yes
I assume the billion that refers to 109. Then 1 billion grams = 1 million kilograms, which equals 1000 metric tons, which is about 2.2 million pounds or 1100 tons(US).

The earth is roughly 4.5 billion years old, give or take a few 'earthdays'.
I assume you are asking what the 13 stars on the US flag represent. It is representative of the 13 original conlonies.
60000000000
I assume you are talking about a political map. In that case it would be donkey or Democrat.

if you are talking about world in flames (I assume you are) then there were over 8.2 million sold in the US and 4 billion worldwide
I assume you are asking: z + 2 = 12Then z would be 12-2=10
