To determine the molecular formula, we first need to calculate the empirical formula mass of C2H5. The empirical formula mass can be calculated by adding the molar masses of each element in the empirical formula: 2(12.01) + 5(1.01) = 29.07 g/mol. Next, divide the molar mass of the compound (58 g/mol) by the empirical formula mass (29.07 g/mol) to find the multiplier: 58 g/mol / 29.07 g/mol = 2. This multiplier gives the molecular formula of the compound, so the molecular formula is (C2H5)2 or C4H10.
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.
If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
If Anna Anderson was cremated how could they test her DNA later?
Not from her ashes, but it is possible to chemically examine clothes worn by Anna Anderson and the real Czarevna- if any survive- under special microscopic light- and body stains, etc could conceivably be tested- as has been done with even inanimate object such as the Shroud of Turn, dating to Biblilcal times. Leave Her residuum alone!If you want to analyze fabrics of her clothes, okay.

Approximately how many degrees mark each time zone?
Theoretically, there are 24 times zones to cover the earth. So each time zone is 1 hour of time difference and 15 degrees. (Divide 360 by 24). However, practically, some time zones are larger than others. The line that seperates time zones are not straight. For example you can travel in the Central Time Zone and cover all of Texas, Arkansas, Mississippi and Alabama before the time changes. I'm sure that is greater than 15 degrees of earth's rotation.
How did colonial New England farmers alter their ecosystem?
Colonial New England farmers altered their ecosystem by clearing forests for farming, draining wetlands for agriculture, and introducing non-native plants and animals. These actions disrupted the natural balance of the ecosystem, leading to soil erosion, loss of biodiversity, and changes in the water cycle.

Natural features are significant land or water that is not man-made. By definition, natural is existing in or produced by nature; not produced by man or artificial.
Geologically, a formation is a natural body of earth, such as an outcrop or deposit with distinctive and characteristic properties allowing study and mapping of the structure or strata on or below the surface.
A feature is typically defined as related to archaeology and consists of man-made or altered items that are not portable and must otherwise be recorded. For the purposes of this section the archaeological component of 'feature' is ignored and redefined as an easier way of describing formations not so apparent to the typical definition.
What will happen if you fill your wetsuit with air?
Assuming you are talking about a wet suit and not a dry suit, nearly nothing. Your suit will dispel the air as soon as you put it in the water. How fast depends on how deep you go (pressure) and how long you are there. Mainly it will be no different then when you put on your wet suit for your first dive of the day when the suit was dry. I do not understand why you would fill your wet suit with air other then possibly it being too loose. If that is the case get one that fits better.
