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.
The measured amount of product.
A first-order reaction will never be completed because the reaction rate depends only on the concentration of one reactant. As the reaction progresses and the reactant is consumed, the concentration of the reactant decreases, causing the reaction rate to also decrease. This gradual decrease in reaction rate means that the reaction will continue indefinitely, given enough time.
it can never be spontanious
The Law of Conservation of Mass states that matter cannot be created nor destroyed. Since atoms comprise matter, any reaction must involve the same number of atoms on the reactants side and the product side.
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.
No, actual yield cannot exceed 100% in a reaction. A yield of 110% would imply that more product was obtained than theoretically possible based on stoichiometry, which is not physically possible. It usually indicates experimental error or incomplete purification of the product.
Reversible reactions never complete because they reach a state of dynamic equilibrium, where the rate of the forward reaction is equal to the rate of the reverse reaction. This means that products are constantly being converted back into reactants and vice versa, preventing the reaction from reaching completion.
why average product labour never gets to zero
No, enzymes are not consumed in a reaction. Instead, they facilitate and speed up chemical reactions by lowering the activation energy required for the reaction to proceed. Enzymes remain unchanged and can be used repeatedly.
The measured amount of product.
When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.

The synthesis of chemicals was so explosive poor Kelly lost a few fingers and his eyebrows.

No, my cat has never licked garlic butter and had a reaction to it.
Not true.
