The solubility constant or Ksp is calculated by the product of the concentration of the ions raise to the stoichiometric coefficient. We calculate as follows:
BaCrO4 = Ba2+ + CrO42-
Ksp = [Ba2+][CrO4]
Ksp = [1.08×10−5<span> ] [1.08×10−5] = 1.1664x10^-10</span>
Answer:
question 3: A
question 4: products and reactants
Explanation:
Explanation:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.
Compound - made out of two or more types of elements chemically combined
Mixture - two or more substances in which the substances retain their identity
Element - simplest form of matter that is present by itself
Put the mixture in water, the pebbles will sink, the pepper will float, and the sugar will dissolve
