let's start by finding the location on the periodic table for the atoms for substances that conduct when dissolved. what do you notice about where the atoms are (metals/non-metals/metalloids)?

Answers

Answer 1

Both will conduct electricity.

Compound Cu(I) chloride - CuCl Compound potassium iodide = KI

Solution:

Both compounds are ionic compounds and in molten or in aqueous solution, both will provide the ions. Ions are conducting chemical species.

As we see the position of K, I, Cu, and Cl in the periodic table, we observe that -

K, Cu are metals

I, Cl are nonmetals.

So when compounds are formed by metals and nonmetals by electrostatic attraction force they are ionic compounds and they are conducting material.

Substances that are insoluble in water and do not conduct electricity are composed of non-metallic atoms. Metals are to the left of the line, non-metals are to the right of the line, and the elements immediately next to the line are semimetals. The physical and chemical properties of the atoms of an element depend on their electronic configuration.

which combination of ionic charge and ionic radius give the largest lattice enthalpy for an ionic compound?

Answers

Combination of ionic charge and ionic radius give the largest lattice enthalpy for an ionic compound are:

 Ionic charge = high, Ionic Radius = small

Understanding Ionic bonds

Understanding Ionic bonds Ionic bonds occur due to the handover of electrons to form positive ions and negative ions whose electron configuration is the same as that of the noble gases.  Positive ions and negative ions are bound by an electrostatic force.  The resulting compounds are called ionic compounds.  One example that we often encounter everyday is table salt.

Well, the chemical formula for table salt is NaCl (Sodium chloride).  In solid NaCl there is a bond between Na⁺ ions and Cl⁻ ions by electrostatic forces, so it is called an ionic bond.  The crystal form of NaCl is a series of Na⁺ ions and Cl⁻ ions.  One Na⁺ ion is surrounded by six Cl⁻ ions and one Cl⁻ ion is surrounded by six Na⁺ ions .

Formation of Ionic bond

Each element must try to have an electron configuration like that of a noble gas, either by releasing electrons or accepting electrons, so that it is stable.  This electron handover event occurs in the NaCl compound/ table salt.

Na belongs to group IA where IA has 1 valence electron, so that to be stable IA must release 1 electron.  If you look at the electron configuration, 11Na: 2, 8, 1. So when removing 1 electron, the last electron becomes 8 (according to the octet rule).  Due to removing 1 electron, the originally neutral Na becomes charged +1 (Na⁺).

 The reaction:

Na → Na⁺ + e⁻   (meaning Na loses 1 electron, see the electron is to the left of the arrow)

Greta passed a comb through her hair several times. She then placed the comb next to a stream of water flowing from a faucet. Greta observed the stream of water bend toward the comb. How did passing a comb through her hair allow the comb to bend the stream of water?.

Answers

Passing a comb through her hair allows the comb to bend the stream of water is option B. by giving the comb an electrical charge.

The comb draws the movement of water in an equal way. The price of the comb attracts the molecules of water within the flow. due to the fact the molecules inside the circulation may be moved without difficulty, the circulate bends toward the comb. because water molecules are polarized molecules, the effect is stronger than with dust.

While a comb is run thru your hair charges pass between your hair and the brush, so the comb turns into charged both definitely or negatively, and the hair is oppositely electrical charge.

The brush, blanketed in negatively charged electrons, becomes negatively charged as nicely, and your hair is left with a high-quality fee.

a gas mixture contains 84 % nitrogen and 16 % oxygen. if the total pressure is 1.19 atm , what are the partial pressures of each component?

Answers

If the total pressure is 1.19 atm than partial pressure of N2 is 0.99 atm and O2 is 0.19 atm.

Define partial pressure.

An idea is the partial pressure of a gas (rather than something we can measure). We consider the pressure of each gas in a mixture to be a component of the combination's overall pressure. Each gas has a certain pressure when contained by itself.

Given,

A gaseous mixture which contains 84% of N₂ and

16% of O₂

The total partial pressure  Ptotal = 1.19atm

Ptotal =  P N₂ + P O₂

% of various component of the mixture, we know the fractional composition of each components:

Partial pressure of component = Fractional composition of component × Total pressure

Partial pressure of component = [tex]\frac{percentage composition}{100}[/tex] × Total pressure

Partial pressure of component of N2 =  84/100 × 1.19 = 0.99 atm

Partial pressure of component of O2 =  16/100 × 1.19 = 0.19 atm

Thus,

partial pressure of N2 is 0.99 atm and O2 is 0.19 atm.

What are the electron and molecular geometries, respectively, for hydrogen sulfide, h2s?.

Answers

Since there are four groups encircling the sulphur atom, the electron geometry is tetrahedral ( 2 lone pairs and 2 hydrogens). Due to the lone pair repulsion of the S-H bonds, the hydrogen sulfide's molecular geometry is bent, something I hadn't encountered in university. As a result, the angle will be much less than 109.5 degrees, or roughly 92 degrees.

The difference between molecular and electronic geometry is that the latter is the geometry of the localised electron densities, whilst the former simply considers the bound substituents around the sulphur, such as the hydrogens ( bonds and lone pairs).

Four of the five geometries linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral are referred to as electron group geometries. The form of the molecule is changed but the electron geometry remains the same if one or more of the bonding pairs of electrons are swapped out for a lone pair.

A student is studying barium, a highly reactive element that is used in some paints. Which characteristic of barium is most closely related to its chemical reactivity?.

Answers

High ionization energy is the property of barium that is most directly connected to its chemical reactivity.

Has barium a high level of reactivity?

Each of their atoms contains two valence (outermost) electrons. Barium has valence electrons in its fifth shell because it is in period 5, or row 5, however it can lose its valence electrons very quickly.

This explains why oxygen and other electronegative substances, like barium, make it so reactive. In a nutshell, when atom size increases, the ionization energy drops.

Barium is larger and has higher energy levels than strontium because it is in a different period—the sixth—than strontium, which is in a different period. As a result, barium will have a lower ionization energy.

Answers

The 4s orbital in the electronic configuration of a germanium should be filled first before 3d orbital because 4s orbital has a less energy than 3d orbital.

The electronic configuration of element is written in the order which is given in the attached image. The order of filling electron is given by Madelung rule in which electrons tries to achieve the order which fills the energy sublevels of atoms. According to the Aufbau principle, electrons occupy the lowest energy sublevel.

In other words, the orbital with a smaller value of n+l will be filled first. The n and l value for 4s orbital is 4 and 0 respectively. The n and l value for 3d orbital is 3 and 2. Hence, their n+l value will be

The solute can have infinite solubility in the solvent when the molecule-to-molecule attractions in the solute are comparable to those in the solvent. The correct option to this question is B

On the basis of the concept, solute has a lower tendency to dissolve in water the stronger the interactions between the solute particles. Likewise, there is a greater chance that solubility will rise the stronger the interactions between the molecules of the solute and the solvent.

Water molecules cluster together as a result of stronger water hydrogen bonds, making them unavailable for biomolecular hydration. If the hydrogen bonds between the proteins significantly strengthen or weaken, the extended denatured forms of the proteins typically become more soluble in water.

Calcium carbonate can be broken down by heating. What is the scientific term for this?.

Answers

The term is called Thermal Decomposition. Calcium Carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium). Bubbling carbon dioxide through these forms a milky suspension of calcium carbonate.

Thermal decomposition is a chemical reaction where heat is a reactant. Since heat is a reactant, theses reactions are endothermic meaning that the reaction requires thermal energy to break the chemical bonds in the molecule.

A common example of thermal decomposition reaction is calcium carbonate decomposes into calcium oxide and carbon dioxide. This process is employed in the manufacturing of quick lime, which is an important substance in many industries.
