cause chemical reactions cant be reversed
No, a chemical reaction involves the rearrangement of atoms to form new substances with different properties. It is not possible to retrieve the original substance once it has undergone a chemical reaction.
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
In a reversible reaction, the products can convert back into the reactants given appropriate conditions. This is often seen in chemical equilibrium where the forward and reverse reactions occur at the same rate.
A chemical change is the same as a chemical reaction.
Carving a statue out of marble is a physical change because the marble is simply being reshaped without undergoing a chemical reaction. The composition of the marble remains the same throughout the carving process.
Yes, chemical weathering involve chemical reactions.
It's chemical because you can't get the pear back to a whole.
A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.
true
They are just two different terms that mean the same thing.

A catalyst doesn't undergo a chemical change during a chemical reaction.
