show two wrong ways to write the symbol of calcium
an arrow -> or sometimes a pair of arrows, one pointing to the right and another under it pointing to the left indicating that the change proceeds in both directions
There is no symbol that will show weather or not heat is needed in a decomposition reaction.
A chemical formula that shows the number and types of atoms in a molecule is known as a molecular formula. Molecular formulas are written by writing the symbol for each element followed by a subscript to show the actual number of atoms in the molecule.
This cannot be shown correctly on Answers. Firstly, if it's charged it's an ion not an atom. The correct notation is symbol then the number as a superscript, then the plus or minus as a superscript.
subscript lower a round the baseline e.g H2O superscript rises a word above the baseline e.g4th

All forms of water are shown as H2O. To show the different states use (g) for gas, (s) for solid, and (l) for liquids. To show added heat, you can use the triangle or "delta" symbol. Just like when writing a balanced chemical equation.
The exponent in this case is the small number written in superscript (raised) to the right of the 10.
900 = 9 x 100 9 can be written as 3 to the power of 2 100 can be written as 10 to the power of 2 It is then written as (3 squared) x (10 squared) I cannot with the editor we use show how to write 3 squared or 10 squared but I hope you know ( 3 superscript 2) x (10 superscript 2).
Yes. However, it is not possible to show them on the browser that we have to use.A superscript o - like in degrees, to indicate hour and a single quotation mark to indicate minutes. A double quotation mark will represent seconds.
A properly written chemical equation will always show the same number of atoms of each elemental on each side, showing that no atoms are created or destroyed in the chemical reaction.
Looks like cubic meters per hour to me, i.e. it should have been written with the 3 as a superscript and a slash between the m3 and the hour - I'll try to show you: m3/hour
Balancing an equation is simply a matter of ensuring that the number of atoms of each specific element that you start with (reactants) are the same as the number that you wind up with (products) in the new arrangements or compounds that they form. And a subscript is the number written halfway below the line, to show how many atoms are in a given molecule; it does not appear (contrary to your assertion) in front of chemical symbols or formulas.
