Answer the following question given this paragraph: An empirical formula is a formula that shows the elements in a compound in their lowest whole-number ratio. Glucose is an important simple sugar that cells use as their primary source of energy. Its molecular formula is C 6 H 12 O 6 . Since each of the subscripts is divisible by 6, the empirical formula for glucose is CH 2 O. When chemists analyze an unknown compound, often the first step is to determine its empirical formula. There are a great many compounds whose molecular and empirical formulas are the same. If the molecular formula cannot be simplified into a smaller whole-number ratio, as in the case of H 2 O or P 2 O 5 , then the empirical formula is also the molecular formula. Q: What is the term for a formula that shows the elements in a compound in their lowest whole-number ratio? Choices: - measured formula - intrinsic formula - Dwarf Formula - empirical formula A:
empirical formula

Answer the following question given this paragraph: When you use a machine, you apply force to the machine. This force is called the input force. The machine, in turn, applies force to an object. This force is called the output force. The output force may or may not be the same as the input force. The force you apply to the machine is applied over a given distance, called the input distance. The force applied by the machine to the object is also applied over a distance, called the output distance. The output distance may or may not be the same as the input distance. Q: What do you call the force a machine applies to an object? Choices: - premium force - drop force - optimal force - output force A:
(A).
output force
Ques:Answer the following question given this paragraph: Q: The energy that enters the chloroplasts as sunlight becomes stored as what type of energy in organic compounds? Choices: - radiation energy - thermal energy - defect energy - chemical energy A:

Ans:chemical energy
Answer the following question given this paragraph: The ice ages were very recent as Earth history goes. The animals are familiar, but they're still very different from modern ones. For one thing, most of them were huge. A small surface area-to-volume ratio is better for keeping warm (less surface to lose heat from). Although the dominant animals were mammals, the Pleistocene Earth still does not look quite modern. Q: The mars rover collected round clumps of crystals that, on earth, usually form in what? Choices: - rocks - volcanoes - air - water A:
water
