What is the net charge of the ionic compound calcium fluoride

yKpoI14uk [10]

Answer:

The net charge of the ionic compound calcium fluoride is zero (0).

Explanation:

Ionic compounds, such as covalent ones, have zero net charge; this is, they are neutral.

Substances with net positive charge are cations and substances with net negative charge are anions.

The charges in the ionic compound calcium flouride are distributed in this way:

Compound formula: CaF₂

Calcium charge: Ca²⁺: this is, each calcium ion has a 2 positive charge

Fluoride charge: F⁻: each fluoride ion has a 1 negative charge.

Then, the net charge is: 1 × (2+) + 2 × (1-) = +2 - 2 = 0.

So, a two positve charge, from one calcium ion, is equal to two negative charges, from two fluoride tions, yielding a zero net charge.

What is the atomic structure of an atom

icang [17]

Answer:

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus. All these three subatomic particles construct an atom.

The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.

Symbol= e-

Mass= 9.10938356×10-31 Kg

It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.

While neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.

Symbol of proton= P+

Symbol of neutron= n0

Mass of proton=1.672623×10-27 Kg

Mass of neutron=1.674929×10-27 Kg

A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

The following data was collected when a reaction was performed experimentally in the laboratory.

Reptile [31]

The maximum amount of $AlCl_3$ produced during the experiment can be find out by knowing the Limiting Reagent.

Here, The maximum amount of $AlCl_3$ produced during the experiment is 400 grams

<h3>What is Limiting reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is stopped.

Now, According to the question,

Given ;

Number of moles of $Al(NO_3)_3$ - 4 moles

Number of moles of NaCl - 9 moles

To Find - Maximum amount of $AlCl_3$ produced during the reaction.

Solution ;

complete reaction ;

$Al(NO_3)_3$ + 3NaCl --> $3NaNO_3$ + $AlCl_3$

To find the maximum amount of $AlCl_3$ produced during the reaction,

we need to find the limiting reagent.

Mole ratio $Al(NO_3)_3$ = 4/1 = 4

Mole ratio NaCl = 9/3 = 3

Thus, NaCl is the limiting reagent in the reaction.

Now, 3 moles of NaCl produces 1 mole of $Al(NO_3)_3$

9 moles of NaCl will produce = 1/3 x 9 = 3 moles.

Weight of $Al(NO_3)_3$ = 3 x 133.34 = 400 grams

Thus, 400 grams of $Al(NO_3)_3$ is the maximum amount of $Al(NO_3)_3$ produced during the experiment.
