Conductivity is directly related to the number of ions present in a solution. Insoluble compounds do not dissociate to any appreciable extent. What kind of conductivity would you expect such a solution to have?.

Answers

Answer: Referring to a solution that does not completely disassociate, the conductivity would be low.

Explanation: Ions that are completely disassociated conduct better than ions that still are connected by bonds.

The kind of conductivity that would you expect insoluble compounds have is very poor or low. Due to this, these compounds do not dissociate to any appreciable extent.

How is Conductivity measured?

Conductivity is measured through the utilization of salinity measurement. This measurement most frequently determines the parts per thousand or grams per liter.

A Siemen is also referred to as its smaller equivalents, the milli-Siemen, and the micro-Siemen, which are each one-millionth of a Siemen, is a unit used to determine the conductivity of any given solution.

Some solutions like NaCl, HCl, NaOH, etc have high electrical conductivity because they readily dissociate into their ions. While insoluble compounds do not have this capability to dissociation, so they generally have low or poor electrical conductivity.

Therefore, insoluble compounds generally have low or poor electrical conductivity.

An atom has a diameter of 2.00 Å and the nucleus of that atom has a diameter of 9.50×10−5 Å . Determine the fraction of the volume of the atom that is taken up by the nucleus. Assume the atom and the nucleus are a sphere.

Answers

fraction of the volume of the atom that is taken up by the nucleus is 1.07x10⁻¹³Å³

Sphere volume is calculated by formula =

V=4/3(πr³) , V is volume , r is radius
Radius = diameter/2

Radius of atom = 2/2=1

Radius of nucleus = (9.50x10⁻⁵)/2 = 4.75x10⁻⁵


now we may calculate the volume for the atom and the nucleus

atom volume = (4/3) × 3.14 × (1 )³ = 4.186 ų

nucleus volume = (4/3) × 3.14 × (4.75× 10⁻⁵)³ = 4.48 × 10⁻¹³Å³

now the fraction of volume of the atom that is taken up by the nucleus:

fraction = nucleus volume / atom volume 

fraction =4.48 × 10⁻¹³/4.186 = 1.07x10⁻¹³Å³

How many of the above contain ionic bonding in them. Write their formulas below. Write one major
reason that how do you come to know that your given answers contain ionic bonding in them

Answers

Answer:

1) The number of the listed compounds that have ionic bonds between them are 5 compounds

2) Their formulas showing their charges within the compounds are;

NaCl ↔ Na⁺+Cl⁻

MgO ↔ Mg²⁺+O²⁻

K₂O ↔ 2K⁺+O²⁻

LiF ↔Li⁺+F⁻

CaO ↔ Ca⁺+O²⁻

3) The major reason they were selected is because they are compounds formed by the combination of a metal and a nonmetal

Explanation:

1) An ionic bond involves the transfer of an atoms valence to another atom, such that the ions formed by the ionic chemical bond will be oppositely charged

Therefore, metals, which are elements that mainly have a few electrons in their outermost shell, loses their valence electrons and become positively charged, while non metals, which require a few electrons to complete the stable octet electronic configuration, receive the electrons from the metallic atoms and become negatively charged

Therefore, the compounds formed between a metal and a nonmetal in the list are the the compounds containing ionic bonds, including

NaCl, MgO, K₂O, LiF, and CaO

Therefore, 5 compounds contain ionic bonds between them;

2) Their formulas are;

NaCl, MgO, K₂O, LiF, and CaO

3) The major reason that the chosen compounds contain ionic bonding between them is because they involve the combination of a metal and a nonmetal as follows;

a) NaCl → Na⁺ (metal ion) + Cl⁻(nonmetal ion)

b) MgO → Mg²⁺ (metal ion) + O²⁻(nonmetal ion)

c) K₂O → 2K⁺ (metal ion) + O²⁻(nonmetal ion)

d) LiF → Li⁺ (metal ion) + F⁻(nonmetal ion)

e) CaO → Ca⁺ (metal ion) + O²⁻(nonmetal ion)

Would neon (ne) normally be expected to form compounds? a. yes, because neon has eight electrons in its outermost level and is unreactive b. no, because neon has eight electrons in its outermost level and is unreactive c. yes, because neon needs six electrons to fill its outermost level d. no, because neon needs six electrons to fill its outermost level

Answers

No, neon normally does not form any compounds because neon has eight electrons in its outermost shell and is unreactive.

Neon belongs to the Group 18 of the periodic table.

The other elements(Helium, argon, krypton, radon, xenon) along with neon present in group 18 are known as noble gases.

All the elements of this group are unreactive and gases.

All these gases except Helium have 8 electrons in their outermost level, which is a stable electronic configuration.

As they have a stable electronic configuration, they don’t have any tendency to accept electrons from other elements or donate their electrons, which makes them unreactive.

Thus, neon normally does not form any compounds because neon has eight electrons in its outermost shell and is unreactive.

If you were to measure the mass of magnesium and hydrochloric acid before combining them in the test tube, how would that mass compare to the mass of reactants left in the test tube after the reaction? Explain your answer and how it corresponds to the law of conservation of mass.

Answers

Answer:

Answer: The mass of product left in the test tube will be less than the initial measured mass of the reactants.

Explanation: This is because one of the products of the reaction is a gas (hydrogen) and it escapes as the reaction happens in an open system.

This is the reaction,

Mg(s) + 2HCl(aq) --------> MgCl2(aq) + H2(g)

So, evidently, only MgCl2 is left in the reaction test tube together with unreacted reactants.

But, the hydrogen gas that escapes accounts for the lesser mass at the end of the reaction.

The mass in the test tube at the end of the reaction +

the mass of Hydrogen gas that escapes = the mass of reactants before the reaction; consolidating the law of conservation of mass.

Answers

The balanced equation :

8Al + 3Fe₃O₄→ 4Al₂O₃ + 9Fe

You just have to look for which element is in bold because the question is not clear

Further explanation

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction

Al + Fe₃O₄→ Al₂O₃ + Fe

give a coefficient

aAl + Fe₃O₄→ bAl₂O₃ + cFe

O, left=4, right=3b⇒3b=4⇒b=4/3

Al, left=a, right=2b⇒a=2b⇒a=2.4/3⇒a=8/3

Fe, left=3, right=c⇒c=3

The equation becomes :

8/3Al + Fe₃O₄→ 4/3Al₂O₃ + 3Fe x3

8Al + 3Fe₃O₄→ 4Al₂O₃ + 9Fe
