AI Thread Summary
The discussion focuses on the process of creating chemicals from molecular formulas and the importance of understanding chemical equations. It clarifies that molecular formulas represent compounds but can also indicate multiple isomers. Making a compound requires specific precursors rather than simply mixing elements in proportion. The conversation highlights that while molecular formulas help determine the quantities of substances in a reaction, they do not indicate the feasibility of the reaction itself. For example, the synthesis of butane from pentanoic acid is discussed, illustrating a specific reaction with its corresponding equation. Learning chemistry is emphasized as essential for understanding how to derive equations from molecular formulas and for grasping the complexities of chemical reactions.

Hey guys i wanted to know how make some chemicals when i have an equation, for example:

First of all, you don't have any equations in the graphic above. These are called the molecular formulas for the various compounds shown.

A typical chemical formula, or reaction, looks like this:

A + B → C + D,

where A and B are the molecular formulas of the reagents, and C and D are the molecular formulas of the reaction products.

There are many different chemical reactions which are studied in chemistry. Some of these reactions can be quite dangerous if proper safety precautions are not employed.

Study some chemistry and then come back if you have any questions.

1- Although these molecular formulae would be recognised as the compounds named, it is not always the case that a molecular formula represents a single compound. It could represent several isomers with different structures.
2 - How you make a compound depends on what precursors you have. In general you can't just mix the elements in the required proportion, heat it and hope to get what you want. Strangely enough the compounds you list are more likely to be starting points for the production of other compounds. (Well glucose certainly; butane and octane are mainly fuels, though they could be partially oxidised to produce more reactive compounds.) They would generally be obtained from a biological source (glucose) or petroleum (butane and octane.)
 
Ok thanks guys, and last question, when i learn chemistry, is that possible i will know how to make equations from a molecular formula?
 
Yes, the molecular formulae help you work out the number of molecules of each substance to put in the equation.
When you make equations, the molecular formulae tell you what numbers to put in, but they don't help you know whether the reaction is likely. If you know that a reaction works, it simply gives you the correct quantities. For example, it is possible to make butane from pentanoic acid by removing CO2, using soda lime. The overall reaction is:
Pentanoic acid + Sodium Hydroxide -> Butane + Sodium Carbonate + water
C5H10O2 + 2 NaOH -> C4H10 + Na2CO3 + H2O

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
