The correct answer is option D, that is, two new compounds.
Double displacement also known as double replacement reactions, metathesis or exchange reactions. It take place when two ionic compounds are exchanged forming two new compounds. One can consider the reaction as swapping the anions or the cations.
Water usually functions as the solvent for a double replacement reaction, and the products and reactants are generally ionic compounds, however, they can also be bases or acids. The example of a double replacement reaction is:
BaCl₂ (aq) + Na₂SO₄ (aq) = BaSO₄ (s) + 2NaCl (aq)
In this, the cations are Na⁺ and Ba²⁺, and the anions are SO₄²⁻ and Cl⁻. If the anions or cations are swapped, the products obtained are BaSO₄ and NaCl.
Answer:
The given statement is false.
Explanation:
Ionic bond is formed by strong electrostatic attraction between two atoms having large difference in their electronegativity.This strong electrostatic attraction provide structural stability to the ionic compounds.For example NaCl.
The ionic compounds generally are solid in nature.As a result their melting point and boiling point are higher that covalent compounds as covalent compounds exist in liquid of gaseous state.
The myth that peppermint makes you smarter, is false, but there are
benefits to the scent of peppermint. Although, eating peppermint
flavored candies is not as beneficial as actually smelling the
peppermint before the test.
Peppermint in
many forms such as tea, candy, and oil can be used to help improve
mental awareness. The menthol “stimulates the Hippocampus area of the
brain which controls mental clarity and memory. The odor triggers you to
wake up and pay attention.” This explains why many people believe that peppermint makes you smarter, when really it makes you more alert.
Peppermint also has the ability to improve athletic performance as well as helping to improve reaction times.
Overall, peppermint can improve your mental awareness but, no, it does not actually make you smarter.
