Learn how to determine the correlation between the mass spectrum & the isotopes masses, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.
How can stable isotopes determine origin and authenticity of food and beverage samples?Food and beverage products have an isotope fingerprint, a unique chemical signature that allows the product to be identified. The variations of isotope fingerprints indicate the real origin and history of...
It's difficult to determine the carbon footprint of a cremation because different amounts of energy are used depending on factors such as the time of day, body size and type of container. To make cremation more ecologically sound, crematory operators can batch cremations to avoid using extra e...
Radiometric dating is a powerful scientific method used to determine the age of the Earth and various geological materials with remarkable precision. The fundamental principle behind radiometric dating lies in the decay of radioactive elements found in rocks and minerals. Certain naturally occurring radio...
For example, let’s go back to the 2-chlorobutane starting with the wedge chlorine: Chlorine is the first priority, then we have two carbons and a hydrogen which gets the lowest priority. We need to determine the second prioritycomparing two carbon atomsandthere is a tiesince they both (ob...
How to Determine HS Code for Chemicals Determining right HS Code for a chemical product is not as difficult as you think. You need to gather the following info as a minium requirement. Whether it is a substance or mixture?Inorganic substances and organic substances are usually classified in Cha...
Determine the abundance of each isotope. If the average atomic mass of a chlorine atom is 35.45 amu, and the first isotope has a mass number of 35 and an abundance of 75.77%, what is the mass number and abundance of the second isotope?...
Explain the isotopic property of C-14 that enables it to determine the age of fossils. How are the carbon cycle and the phosphorus cycle similar? How are they different? How does a negative ion form? What charge ion would the atom Calcium (Ca) make, and why? Explain how hypothyroidism ...
How would you find the atomic number, atomic mass, protons, neutrons and electrons for ions and isotopes? How many isotopes does darmstadtium have? What does the number next to isotopes signify? How could you determine the number of neutrons in a carbon 14 atom? How many total number of ne...
LADEE’s mission was designed to determine the origins of the moon’s atmosphere. Scientists hoped that the probe’s remote measurements of soil and atmospheric composition might correlate with certain space weathering processes that could then explain how the moon’s atmosphere came to be. ...
