How many atoms are in the molecule nitrogen trichloride NCl3 )? There are3 chlorine atoms and one nitrogen atomin NCl3. Nitrogen trichloride (NCl3) lewis structure contains three N-Cl bonds. There are one lone pair on nitrogen atom and three lone pairs on each chlorine atom. What can bond...
How many chlorine atoms are in 4.3 grams of phosphorous trichloride? If sodium and potassium are both ions with a positive charge, how can they make something negative? Why does an electron cloud want to have a stable amount of electrons per energy l...
How many moles of atoms are in 4.63 x 10^21 Ca atoms?Question:How many moles of atoms are in 4.63 x 10^21 Ca atoms?The Mole:In chemistry, the mole is used for working with large numbers of atoms. Specifically, 1 mole of a substance contains 6.022×1023 atoms of the substance. This...
An atom, ion, or elements with a valence of one (they can either donate or accept two electrons), which can form one covalent bond is called monovalent. Examples for monovalent atoms are Hydrogen, Sodium, Chlorine, etc. An atom, ion, or elements with a valence of two, is called divalen...
How many single bonds are in the Lewis structure for CH4? Lewis Structure: An atom forms a single covalent bond with another atom through the atoms sharing one valence electron pair. If the starting atom originally contains several valence electrons, then it can form multiple covalent bonds ...

To deal with this issue, scientists came up with a way to standardize talking about how many atoms or molecules are reacting in a given situation. The mole (abbreviation mol) is the SI unit for the amount of a substance. It is defined as about 6.022 x 1023 atoms or particles or things...
Although there are many types of lasers, all have certain essential features. In a laser, the lasing medium is “pumped” to get the atoms into an excited state. Typically, very intense flashes of light or electrical discharges pump the lasing medium and create a large collection of excited-...
H2O = 2 + 16 = 18 g/mol (look at the subscript to note there are 2 hydrogen atoms) Use this value to convert the total number of grams of water into moles: (1 mol / 18 g ) * 100 g = 5.56 moles of water Now you have the information needed to calculate mole fraction. ...
A pair of sunglasses seems so simple -- it's two pieces of tinted glass or plastic in some sort of plastic or metal frame. How much more straightforward can something get? It turns out that there are many different things you can do with two pieces of glass, and these things can have...
