In a bronsted lowry proton transfer reaction, the
hydroxide functions as a/an <u>proton acceptor.</u>
Bases are the opposite of acids. Bases are basic since they
take or accept protons. For example, a Hydroxide ion can accept a proton to
form water.
The answer should be C.
In the website, the purpose of it is to promote the product, therfore, they will claim all the benefits, no matter it is true or not.
However, in a university study, the purpose is not to promote. They will make sure the test fair and reliable. They have the best equipments and tools and the top investigators.
Therfore, a university study is the best source.
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.

Answer:
The correct answer is - B. dissolving → evaporation filtration → crystallisation
Explanation:
The method of the preparation of a pure sample of copper(II) sulfate from dilute sulfuric acid and copper II oxide is given as follows:
step 1. Adding dilute sulfuric acid into a beaker. Using bunsen burner heat the beaker.
step 2. Adding the copper (II) oxide into the beaker and give it a little time at a time to the warm dilute sulfuric acid and stir
step 3. Filtering the mixture into an evaporating vessel to remove the excess copper (II) oxide and water from the filtrate.
Step 4. leave the rest filtrate to crystallize.
Copper (II) Oxide {CuO (s)} + Dilute Sulfuric Acid {H2SO4 (aq)} → Copper (II) Sulphate {CuSO4 (s)} + Water {H2O}
