Are Fossil Fuels Our Savior and What Are Their Chemical Properties?

AI Thread Summary
The discussion centers around various aspects of fossil fuels and their properties. It begins with the equation for complete combustion of hydrocarbons, questioning whether energy is considered a product. The topic then shifts to laboratory practices, specifically the use of glass wool in fractional distillation of crude oil, which serves to filter impurities. The shape of the flame produced by burning crude oil is noted to be triangular and pointed upward, though there is uncertainty about this observation. The advantages of liquid fuels over solid fuels are highlighted, emphasizing their ease of storage and lighter weight due to their ability to conform to the shape of their containers. Additionally, a distinction between toxic and poisonous substances is briefly mentioned. The conversation suggests that the questions posed are relatively straightforward and encourages more independent thinking before seeking answers.

Fossil fuels-- rescue me please

Equation of complete combustion of hydrocarbon-- hydrocarbon + oxygen -> carbon dioxide + water. Is energy included in the products?

Simple fractional distillation of crude oil carried out in laboratory-- Why the crude oil is soaked by the glass wool? Can we add crude oil into the test tube without the glass wool?

Why is the shape of the flame of crude oil a triangle pointed 'very upward'?

A sentences in my chem notes-- Liquid fuels are easier to store and lighter than solid fuels. Why?

How to distinguish between toxic and poisonous?

You seem to have no brainstorming. These are almost fairly easy to answer.

How do you heat your home? Don't you burn something to obtain thermal energy?

Crude oil may have some impurities, glass wool is an impermeable plug here. You somewhat "filter" the crude oil by doing this.

I have not heard of a triangle, so I'm stuck here.

Remember-liquids are easier to store, since they get the shape of the container.

I must say that these are very easy to answer, please do some brainstorming before submitting your thread.
 
okay...thx
 

Thread 'Solubility of MgSO47H2O in water'

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...

Thread 'Why does having 8 valence electrons make an element inert?'

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!!
