To do this, look up atomic masses on the periodic table and use the formula mass to know how many atoms of each element are in a compound. Remember, subscripts in a formula indicate number of atoms. If there is no subscript, it means there is only one atom of that element in the fo...
How many eggs are in 8.11 *106moles of eggs? Mole: The mole is a unit of measurement, a specific quantity of items similar to a dozen. The unit of mole is convenient because one mole of atoms or molecules weighs a specific mass, referred to as the molar mass of a substance. ...
Ideally, the level of pH in the pool should be between 7 and 8; 7.4 is ideal -- this is the pH of human tears. Once the HOCl and OCl- are done cleaning the pool, they either combine with another chemical, such as ammonia, or are broken down into single atoms. Both of these ...
In this video, we learn how to properly balance chemical equations. You will see what substances are in each side of the equation. You will then need to count the atoms that are on each side of the chemical equation. Once you write down the number of atoms on each side, you will need...
17.Toothpaste– After reading many online testimonials of people using toothpaste on cold sores, as well as articles written by doctors, I now have a detailed overview of this subject matter. Here are the key concepts: Some bloggers claim the ingredient sodium lauryl sulfate (SLS) found in man...
My “combinatorics” starts from doing the permutations of every combination of just a few atoms, to see what exists. Many of the small molecules polymerize, if they are reactive. Methylamine is really the only alternative. Hydrazine is I doubt a gas, and I suspect carcinogenic. Nongas items...
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-...
the grand-scale frequency comb, the new atomic clock is more than just a clock. In the future it may be used to map the Earth's gravitational field, perform tests of fundamental laws of physics, including dark matter searches, and explore the quantum behavior of many atoms working ...
It would not be wrong to say that many of us have had this question buzzing in my head since childhood. But as they say, necessity is the mother of invention. So, submarines have their means of producing oxygen continuously to help their crew stay underwater for days at a stretch. ...
the luminol loses nitrogen and hydrogen atoms and gains oxygen atoms, resulting in a compound called 3-aminophthalate. The reaction leaves the 3-aminophthalate in an energized state -- the electrons in the oxygen atoms are boosted to higher orbitals. The electrons quickly fall back to a lower...
