Answer:
HI(aq) + NaOH(aq)-------------> NaI(aq) + H2O(l)
Explanation:
The molecular reaction between hydroiodic acid and aqueous sodium hydroxide is shown above. It is a reaction of one mole of hydroiodic acid with one mole of sodium hydroxide to yield salt and water only. It is a neutralization reaction. Hydrogen iodide dissolves in water to produce hydronium ions which agrees with Arrhenius description of acids. Hydroiodic acid is a strong acid with PKa of -9.3
Correct Answer: option B. moderately polar covalent
Reason:
Both phosphorus and oxygen are non-metals, and hence they are bonded by covalent bonds. Furthermore, the electro negativity of P and O is 2.1 and 3.5 respectively. The difference in electro negativity is 1.4. Due to the difference in electro negativity, nature of the P-O bond in phosphorus pentoxide (P2O5) is moderately polar covalent.
X * 0.10 mg/mL = 0.50 mg
x = 0.50 mg / 0.10
x = 5.0 mL

Answer: there are 90 lemons in 10 oranges
Answer:
Mineral hydration.
Explanation:
Mineral hydration is a chemical reaction where water is added to the crystal structure of a mineral, usually creating a new mineral sometimes called a hydrate. The process called mineral hydration is known as retrograde alteration and is a process occurring in retrograde metamorphism.
Examples are: Silicates - Chlorites and Non-sillicates - Carbonates, oxides etc.
