What type of reaction will occur with the following reactants?
zalisa [80]

Answer:

A) double replacement

Explanation:

Chemical equation:

NaCl +CaS    →    Na₂S + CaCl₂

Balanced chemical equation:

2NaCl +CaS    →    Na₂S + CaCl₂

The given reaction is double replacement reaction in which cation and anions of each reactant exchange with each other.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AD +CB

Other options are incorrect because,

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

AB → A + B

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

lorasvet [3.4K]

Answer:

n = 0.01302 moles

Explanation:

Pressure = 1.3 atm

Temperature = 31 °C + 273 = 304 K ( Converting to kelvin temperature)

Number of moles = ?

Volume = 250 mL = 0.250 L

These quantities are related by the equation below;

PV = nRT

n = PV / RT

n = (1.3 * 0.250) / (0.0821 * 304)

n = 0.01302 moles

2.41 What is an ionic compound? How is electrical neutrality maintained in an ionic compound?
kiruha [24]

Answer:

Explanation:

An ionic compound is a compound in which electrovalent bonds joins the atoms together. Here, electrons move from a less electronegative atom to a more electronegative one. The formation of ionic bonds involves the transfer of elecrons.

The transfer of electrons makes the atoms charged i.e ionized. These oppositely charge ions establishes an electrostatic force of attraction to form the ionic compounds.

How is electrical neutrality maintained in an ionic compound?

Electrical neutrality is maintained in an ionic compound because the compound is made up of ions in which the net charge is zero. There is a transfer of electrons which is completely recieved by the more electronegative atom.
