If the atoms come from different elements, the molecule will be called a compound. Molecules can have as few as two atoms or hundreds of atoms.Answer and Explanation: There is no way to know how many molecules are in a tablet weighing 500 mg without knowing the molecules in the table. E...
How many valence electrons are in each of the following atoms? a. Mg b. C c. Br d. Cs How many valence electrons are visible in the Lewis structure of phosphorus (P)? Construct the Lewis structure model for the covalent compound sulfur difluoride using the following steps...
Sulfur occurs naturally as the element, often involcanic areas. This has traditionally been a major source for human use. It is also widely found in many minerals including iron pyrites, galena, gypsum and Epsom salts. Elemental sulfur was once commercially recovered from wells by the Frasch pr...
Into how many peaks is each signal split? Nuclear Magnetic Resonance Nuclear Magnetic Resonance spectroscopy is an analytical method to predict the structure of an organic compound. The NMR spectra show signal peaks, indicating hydrogen atoms' splitting. The n+1 rule calculates the splitting. ...
In this upper atmosphere, ozone is made when ultraviolet light from the sun splits an oxygen molecule (O2), forming two single oxygen atoms. If a freed atom collides with an oxogen molecule, it becomes ozone. Stratospheric ozone has been called "good" ozone because it protects the Earth's...
their atoms. A hole is left behind in each case. These electrons, called free carriers, then wander randomly around the crystalline lattice looking for another hole to fall into and carrying an electrical current. However, there are so few of them in pure silicon that they aren't very ...
There are many other ways to generate thrust however. Any system that throws mass would do. If you could figure out a way to accelerate baseballs to extremely high speeds, you would have a viable rocket engine. The only problem with such an approach would be the baseball "exhaust" (high-...
formation. Combined with nitrogen, sulfur forms many amino acid chains, which are the building blocks of proteins. Sulfur is also critical in the process of photosynthesis. Since photosynthesis is a crucial process where a plant synthesizes its own food, ensuring sufficient sulfur is present is ...
How many atoms does a molecule of CO2 have? How many molecules of silicon dioxide are there in 560 g of silicon dioxide? How many electrons are in a double bond? What is a pi bond? How many p orbitals are present on an sp3-hybridized carbon atom?
