It can. As an example Hydrogen gas - an element, is produced by a metal reacting with an acid or water. There are many other examples. Photosynthesis produces oxygen which is an element. Reduction of iron ore and other ores produces elements.
A reactant in a decomposition reaction can never be an element because by definition, an element can not be broken down any further.
Man, I'm looking for this answer too.
The measured amount of product.
Catalysts are never consumed in the reaction. that's what makes them catalyst! not a reactant. they increase the rate of reaction by lowering the activation energy for the reaction. One of the ways to do this by providing an alternative route for the reaction to follow.
In any reaction, a catalyst is never used up or changed. This means that at the end of every reaction you should always get your catalyst back. sometimes in the course of the reaction, the catalyst is used up, but by the end of the reaction it will always be reformed completely.
Firing a forest is a chemical change because you change a wood into ashes and never reverse it back again
it can never be spontanious
No. There is no type of a catalyst that is consumed in a reaction.
No, a reaction can never have an actual yield of 110. If an actual yield of 110% if obtained, then the product must contain impurities which increase the experimental mass.
The measured amount of product.
When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.
Because reversible reactions are continuting process as well two way process.reactant n product convert into one another and in this way reaction will continue.
The synthesis of enzymes would stop.
why average product labour never gets to zero
The synthesis of chemicals was so explosive poor Kelly lost a few fingers and his eyebrows.
never
Enzymes are specialized proteins that facilitate chemical reactions in the body by lowering their activation energy, or the energy required to initiate a reaction. They are never consumed by the reaction themselves; therefore, enzymes can be re-used many times. Enzymes are specific to a particular substrate and usually facilitate the reaction by undergoing a conformational change when encountering the substrate, transforming it into a product or an intermediate.
they never did
The product of two odd numbers is never even.
