boron because the farther down the table you go the stronger the elements get
Transition Metals can have more than one possible charge.
Answer:
At chemical equilibrium, the amount of product and reactant remains constant, because the rates of the forward and reverse reactions are equal.
Explanation:
At equilibrium, the forward and reverse rates become constant, so the concentrations of reactants and products also become constant.
Answer: (3) silicon
Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Silicon (Si)
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: ethane , propanone and water
