Answer: gasoline
Explanation:
An aqueous solution is one which contains water as a solvent. A non- aqueous solution is the one in which the solvent of the solution is a liquid but it is not water.
Among the options given, gasoline is the correct option. This is because of the fact that gasoline is a crude oil which does not include water as an ingredient.
The chemical reaction produces a new substance with new and different physical and chemical properties. Matter is never destroyed or created in chemical reactions. The particles of one substance are rearranged to form a new substance. .
All substances are matter but all matters are not substance. Matter is generally a loose term used in respect to a substance. Matter and substance are sometimes used for the same context, this is certainly not correct. Various examples have already proved that a matter will not always be a substance depending on its physical nature, but a substance is always a matter.
(cc/ to Taskmasters , I just switched it up a little bit.)
A 'spontaneous reaction' in chemistry refers to a reaction that continues on its own once started, not a reaction that starts spontaneously. A sparkler, once lit, undergoes a combustion reaction that needs no additional energy input.
The term spontaneous reaction in chemistry does not mean that a reaction starts spontaneously without any trigger. It actually refers to a reaction that, once started, continues without any additional external input. In the case of a sparkler, the initial energy to start the reaction is provided by lighting the sparkler. Once lit, the combustion reaction continues on its own, making it a spontaneous reaction.
The reactants in the sparkler (often metal powders and an oxidizing agent) are in a higher energy state than the products (typically metal oxides and heat) they form during burning. This difference in energy drives the reaction forward, making it spontaneous. The overall energy of the system decreases, which aligns with the principle of thermodynamics stating that a spontaneous process leads to a decrease in the system's free energy.
