what has very good electrical conductivity

Answers

Answer 1
Many metals have very good electrical conductivity. This is because metals have a large number of free electrons in their outermost energy levels, which are able to move freely through the metal's structure. This allows metals to easily conduct electric current.

Some examples of metals with very good electrical conductivity include copper, silver, and gold. These metals are often used in electrical wiring and other applications where good conductivity is important.

In addition to metals, other materials can also have very good electrical conductivity. For example, some electrolytes, such as certain solutions of salts, can conduct electricity very well. This is because electrolytes contain ions that are able to move freely through the solution, allowing electric current to flow.

Overall, materials with good electrical conductivity have a high number of free electrons or ions that are able to move freely through the material, allowing electric current to flow easily.

The volume of the solution is 1.84 × [tex]10^{4}[/tex] L.

The formula used to get the molarity of the solution is used to determine the volume of the solution:

Molarity= [tex]\frac{Mass of the solute}{molar mass of solute * Volume of solution(in L)}[/tex]

We are given:

Molarity of solution = 8.75 × [tex]10^{-5}[/tex] M

Given the mass of silver (II) oxide = 200 g

Molar mass of silver (II) oxide = 124 g/mol

Put the values in the formula:

8.75 × [tex]10^{-5}[/tex][tex]10^{-5}[/tex] = [tex]\frac{200}{124* Volume}[/tex]

Volume= 1.84 × [tex]10^{4}[/tex] M

A chemical species' concentration in a solution, specifically the amount of a solute per unit volume of solution, is measured by its molar concentration. The most used molarity unit in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units.

if we use a to represent the cations (in blue) and x to represent the anions (in green), what is the empirical formula of this ionic compound?

Answers

The empirical formula for the compound if A denotes the cations and X denotes the anions is AX₂

It is given that the cations are denoted by Blue color and the anions with green color. There are 8 atoms in the corners and 6 in the face center. Then,

No of atoms in a total of all corners = 8 x 1/8

No of atoms in the corners = 1

No of atoms in the faces = 6 x 1/2

No of atoms in the faces = 3

Then,

Total no of cations atoms = total number of atoms in the corners + the total number of atoms in the faces

Total number of cations (A) = 1 + 3

Total number of cations (A) = 4

The total number of anions in the cell is 8 from the figures as they aren't shared with another lattice arrangement. Therefore,

Number of anions (X) = 8

when 2.16g of h2 reacts with excess o2 by the following equation, 258kj of heat are released.  the change of enthalpy associated with the reaction of 1.00mol of hydrogen gas is -241 KJ

Molar mass of H2 = 2.016 g/mol,mass(H2)= 2.16 g

use:number of mol of H2,n = mass of H2/molar mass of H2=(2.16 g)/(2.016 g/mol) = 1.071 mol

For 1.071 mol of H2, heat released = 258 KJ So,

for 1 mol, heat released = 258/1.071 KJ = 241 KJ

Since this is heat released, sign will be negative

Answer: -241 KJ. The amount of energy progressed or subsumed in a reaction at constant pressure is referred to as enthalpy change. It is represented by the symbol ΔH, read as "delta H". It should be noted that the term "enthalpy change" only pertains to reactions performed at constant pressure.
