Single replacement reactions. For example copper is more reactive than silver. So a copper wire in a silver solution will cause the silver to become a metal again.
Answer:
Take a long time
Explanation:
Geology is defined as a science mostly concerned with the study of the history of the earth as recorded in different rocks formations.
Geologic processes are events that occur on a geological timescale which may span across many centuries.
The four major geologic process are known to include; impact cratering, volcanism, tectonics, and erosion.
Answer:
Exothermic reactions feel hot
Endothermic reactions feel cool
Explanation:
In an exothermic reaction, heat is given out by the system. The energy of the reactants is greater than that of the products hence the excess energy is given off as heat. The reaction vessel feels hot.
In an endothermic reaction, the energy of products is greater than that of the reactants hence energy is taken into the system and the reaction vessel feels cool.
These ions are polyatomic ions. The prefix "poly-" means "many," and the rest of the word "atomic" clearly refers to the atoms themselves. So, if there are two or more atoms in an ion, this ion is polyatomic.
