Explanation:
Mol is the amount of molecules in something. Mol are similar to donuts, if you have a dozen of something you have 12 of them. If you have a mol of Hydrogen gas you 6.02•10^23 molecules of Hydrogen gas. If you are taking a chemistry class you will probably receive questions involving converting grams to mol and vice versa.
Converting Grams to Mol:
grams of x•(1/molecular mass of x)
note: you can find molecular mass of x by looking at the masses of the elements you need to add up in the periodic table
Converting Mol to Grams:
mol of x•(molecular mass of x)
<h2>The net ionic equation that correspond to Fe(ClO4)2 +Na2CO3 is</h2>
<u>Fe ^2+(aq) +CO3^2-(aq) → FeCO3 (s)</u>
<h3>Explanation</h3><h3 /><h3>write the balance chemical equation</h3>
Fe(ClO4)2 (aq) + Na2CO3(aq)→ FeCO3 (s) + 2 NaClO4
<h3>write the ionic equation</h3>
Fe^2+(aq) + 2ClO4 ^-(aq) + 2Na^+(aq) +CO3^2- (aq) → FeCO3 (s) + 2Na^+ + 2ClO4^-
<h3>cancel the spectator ions in both side</h3>
- that is ( 2ClO4^- and 2Na+)
the ionic equation is therefore
<u>Fe^2+(aq) + CO3^2- →FeCo3(s)</u>
An endothermic reaction needs energy to proceed, such energy is usually taken from the environment surrounding the reaction. In the typical case this energy is expressed as heat. Heat is an state of atomic activity, that energy is transferred to an ENDOthermic reaction so the initial threshold of reaction is overcome and the final reaction can occur.
