Atmospheric properties, tectonic plates... there are multiple.
An Olympic decoration is granted to effective contenders at one of the Olympic Amusements. There are three classes of decoration: gold, granted to the victor; silver, granted to the first sprinter up; and bronze, granted to the second sprinter up.
Observations in the scientific method lead to questions which need answers. The hypothesis is a testable argument presented in scientific method to address a question. Experiments (often with controls and variables) are formulated in the experimental method for evaluating theories. Hope this helps ✨

<h3>Further explanation </h3>
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
11.5 g of Ethanol-C₂H₅OH contains 6.00 g of Carbon and 1.51 g of Hydrogen.
mass of Oxygen :
![\tt 11.5-(6+1.51)=4~g](https://tex.z-dn.net/?f=%5Ctt%2011.5-%286%2B1.51%29%3D4~g)
Percent composition :
![\tt \dfrac{6}{11.5}\times 100\%=52.2\%](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B6%7D%7B11.5%7D%5Ctimes%20100%5C%25%3D52.2%5C%25)
![\tt \dfrac{1.51}{11.5}\times 100\%=13.1\%](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B1.51%7D%7B11.5%7D%5Ctimes%20100%5C%25%3D13.1%5C%25)
![\tt \dfrac{4}{11.5}\times 100\5=34.7\%](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B4%7D%7B11.5%7D%5Ctimes%20100%5C5%3D34.7%5C%25)
Answer: When converting from Scientific Notation to a standard or normal notation, use the value of the exponent to determine the number of places to move the decimal point. Move the decimal place to the right if the exponent is positive and move the decimal place to the left if the exponent is negative.
Explanation: I got this from a website but I still hope it helps!
