Answer:

C) Ni(NO₃)₂.6H₂O

Explanation:

<u>Given:</u>

Formula name : nickel(II)nitrate hexahydrate

<u>To determine:</u>

The molecular formula

<u>Explanation:</u>

In the given compound:

Nickel is a transition metal with the symbol Ni and occurs as a cation

Nitrate is a polyatomic anion with a charge -1 i.e. NO₃⁻

The roman numeral 'II' implies that the oxidation state of Ni is +2

Since the compound is neutral the charge on the cation and anion needs to be balanced. As a result the molecular formula is: Ni(NO₃)₂

Hexahydrate implies that there are six (hexa) molecules of water of hydration

The formula is therefore: Ni(NO₃)₂.6H₂O

When is an electric charges neutral ??
dangina [55]

Answer:

Atoms of matter are electrically neutral because their nuclei contain the same number of protons as there are electrons surrounding the nuclei. Electric current and charged objects involve the separation of some of the negative charge of neutral atoms.

Identify the precipitate(s) of the reaction that occurs when a silver nitrate solution is mixed with a sodium chloride solution.
klio [65]
Hello!

The precipitate of the reaction that occurs <span>when a silver nitrate solution is mixed with a sodium chloride solution is silver chloride (AgCl). 

The chemical equation for this precipitation reaction is the following:

AgNO</span>₃(aq) + NaCl(aq) → AgCl↓(s) + NaNO₃(aq)

Silver Chloride is a chemical compound that is poorly soluble in water because the chemical bond between Ag⁺ and Cl⁻ is very strong as the two ions are nearly the same size and have similar electronic densities. If the chemical bond is strong, it is more difficult for water molecules to break this bond to surround the individual ions, and thus solubility will decrease. 

Have a nice day!

The following is an example of which type of chemical reaction?Na (s) + H2O (l) Imported Asset NaOH (aq) + H2 (g)
lora16 [44]

Answer:

The answer to your question is Single replacement

Explanation:

Data

Chemical reaction

                 Na  +  H₂O  ⇒   NaOH  +  H₂

Single replacement  is a chemical reaction in which a metal replaces the cation of a compound.

Decomposition  is a chemical reaction in which a compound forms 2 or more products.

Double replacement  in this chemical reaction two compounds react interchanging their cations and anions.

Combustion in this chemical reaction the reactants must be a compound with carbon and the other oxygen and the products must be carbon dioxide and water.
