Answer:

D. 2 NaNO₃

Explanation:

A double displacement reaction is a type of reaction where two reactants exchange ions to form two new compounds. Double displacement reactions typically result in the formation of a product that is a precipitate.

Double displacement reactions take the form:

AB + CD → AD + CB

For the reaction:

Zn(NO₃)₂(aq) + Na₂S(aq) → ZnS(s) + X

If Zn bond with S, NO₃ must be react with Na to produce NaNO₃ that is a soluble salt (Is in aqueous state (aq)). As there are 2 Na and 2 NO₃ the right answer is:

Explain with equations and calculations, when necessary, whether an aqueous solution of each of these salts is acidic, basic, or

Lelechka [254]

(CH₃)₂NH₂Br is an acidic salt.

<h3>What are acidic salts?</h3>

Neutralization of a strong acid with a weak base gives an acidic salt.

Examples: Ammonium chloride, Copper sulfate, Silver nitrate

<h3>What are basic salts?</h3>

Neutralization of a weak acid with a strong base gives a basic salt.

Examples: Sodium Acetate, Potassium cyanide, Sodium sulfide

<h3>What are neutral salts?</h3>

They are formed by the neutralization of strong acids and strong bases, are called neutral salts because their aqueous solutions are neutral to litmus.

Examples: The compounds like NaCl, KCl, K2S04, NaN03, KCl03, KClO4 etc. are neutral salts.

irinina [24]

These are diseases that affect primarily the lungs or any other part of the respiratory system.

<h3>What are respiratory disorders?</h3>

The term respiratory disorders refers to those diseases that affect primarily the lungs or any other part of the respiratory system. These are the diseases that prevent a person from breathing in and out normally and prevent the lungs from playing its usual role in gaseous exchange.

The respiratory disorders could be able to make a person not to be able to breathe well and it may lead to hospitalization and death of the patient of adequate treatment is not sought from an expert who could diagnose and treat such respiratory disorders.

The common types of respiratory disorders are;

asthma
cystic fibrosis

Materials in Earth's interior?

Alina [70]

Answer:

The inner core is the Earth's "interior".

P-waves pass through both the mantle and core, but are slowed and refracted at the mantle / core boundary. Whereas, S-waves pass from the mantle to the core and are absorbed due to shear waves being incapable of transmitting through liquids. Therefore, this is (further) proof the outer core does not behave like a solid substance.

Determine the net number of sigma bonds, the net number of pi bonds, and the overall bond order for N2+. Use 0.5 to indicate a f

trapecia [35]

Answer:

Net number of sigma bonds = 1

Net number of pi bonds = 2

Overall bond order = 3

Explanation:

Electronic configuration of N2 ia

1s2 2s2 2p3

There is head to head overlap in pz orbital. Thus, there is one sigma bond

Pi bond is formed whenever there is side wise overlapping. Since both px and py undergoes overlapping to form pi bond, there are two pi bonds

Bond order = 0.5 (bonding electron – antibonding electron)

= 0.5 (8-2) = 0.5*6 = 3
