How can one write a condensed structural formula?
To write a condensed structural formula, use a simplified way to represent the atoms and bonds in a molecule. Instead of showing all the atoms and bonds, only the essential parts are included. This helps to quickly and clearly show the structure of the molecule.
How many H atoms would be needed to react with all the N atoms shown in the transparency?
You would need 6 hydrogen atoms to react with the 3 nitrogen atoms shown in the transparency. This is based on the stoichiometric ratio of 2 moles of hydrogen to 1 mole of nitrogen in the formation of ammonia (NH3).
What are the chemical formulas for water and hydrogen peroxide?
The chemical formula for water is H2O, meaning it has two hydrogen atoms and one oxygen atom. The chemical formula for hydrogen peroxide is H2O2, indicating it has two hydrogen atoms and two oxygen atoms.
How many atoms are in C8H16?
24: The answer to the number of atoms present in a formula that does not include parentheses is always the sum of all the subscript numbers in the formula plus one for each type of atom shown without a subscript. If the formula does contain parentheses, all the subscript numbers inside the parentheses should be multiplied by the subscript number after the closing parenthesis itself before the sum of all subscripts is taken.
What are formulas for a compound with one calcium atom and two fluorine atoms and a compound with two aluminum atoms and three sulfur atoms?
Calcium fluoride has the chemical formula CaF2, where there is one calcium atom and two fluorine atoms bonded together. Aluminum sulfide has the chemical formula Al2S3, where there are two aluminum atoms and three sulfur atoms bonded together.
What is a semi condensed formula?
A semi-condensed formula is a shorthand way of representing a molecule's structure where covalent bonds are shown but not all atoms or bonds are explicitly drawn. It strikes a balance between a fully condensed formula (where only bonds between atoms are shown) and a structural formula (where all atoms and bonds are depicted).
How does a complete structural formula differ from a condensed structural formula?
------ The condensed structural formula is simply a shortened version of the complete structural formula. -------The complete formula indicates all of the carbon and hydrogen atoms. The condenced formula groups the hydrogen atoms with each of the carbon atoms.
How does a complete structural formula differ from condensed formula?
The complete or full structural formula shows all the atoms and their bonds separately. The condensed structural formula shows the atoms present but does not show the bonds.
How can one write a condensed structural formula?
To write a condensed structural formula, use a simplified way to represent the atoms and bonds in a molecule. Instead of showing all the atoms and bonds, only the essential parts are included. This helps to quickly and clearly show the structure of the molecule.
What is a condensed structral formula?
A chemical formula that shows the arrangement of atoms and their bonds. As the previous guy said, it is a representation that shows the arrangement of atoms and their bonds. Types are: 1. Lewis structures...simple representation which do not show the arrangement of atoms in the 3-d space. Hence generally used for small molecules. for the 3-d arrangement, we have Fisher, Newman, and Haworth projections.
What are all chemical formulas called?
All chemical formulas are called chemical notations. They represent the elements and the number of atoms of each element present in a compound.
How do you name formulas?
You name formulas by what they are made of. i.e. sugar= C6H12O6. Since sugar (plant sugar) is made from 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms, they all add up to C6H12O6.
How many H atoms would be needed to react with all the N atoms shown in the transparency?
You would need 6 hydrogen atoms to react with the 3 nitrogen atoms shown in the transparency. This is based on the stoichiometric ratio of 2 moles of hydrogen to 1 mole of nitrogen in the formation of ammonia (NH3).
How do you show formulas all on one page in excel 2007?
By pressing Ctrl and `(apostrophe not single quote) the formulas will be shown instead of the values. However, this will have the effect of widening all of the cells in order to show the formulas, some of which may be quite long. So if there are lots of formulas then it may not be possible to get them all to appear on the screen at the same time or on one printed page.
How many atoms make up a molecule of h2o?
Add all the subscripts in the formula, including an implicit subscript of 1 when no explicit subscript is shown: 2+1 = 3 atoms total for H2O.
Why are the numbers all so small and written lower than normal in chemical formulas?
The subscript Number of atoms of that element in the molecule.
What are the chemical formulas for water and hydrogen peroxide?
The chemical formula for water is H2O, meaning it has two hydrogen atoms and one oxygen atom. The chemical formula for hydrogen peroxide is H2O2, indicating it has two hydrogen atoms and two oxygen atoms.
