Answer:

LiCl because the total negative charge on Cl is one.

Explanation:

Lithium has a charge of 1+ and Chlorine has a charge of 1-.

There are two types of chemical compound one is covalent compound and other is ionic compound. LiCl because the total negative charge on Cl is one. The correct option is option A.

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

Covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Ionic compounds are hard, these have higher melting and boiling point than the covalent compounds. Li act as cation Li⁺ and Cl act as Cl⁻. These two combine to form LiCl. LiCl is an ionic compound.

Therefore, LiCl because the total negative charge on Cl is one. The correct option is option A.

Most all of the visible light striking the snow or ice surface is reflected back without any particular preference for a single color. Most natural materials absorb some sunlight, which gives them their color. Clean snow, however, reflects most of the sunlight, creating a white appearance.

Explanation:

Answer:

For Feo is 2+

For Fe2O3 is 3+

Btw I did it and got it right!

Explanation:

The charge of the Fe ion in the compound [tex]\rm FeO[/tex]is +2 and the charge of the Fe ions in the compound [tex]\rm Fe_2O_3[/tex] is +3, respectively.

Ion can defined as any atom or molecule having positive or negative charge on it.

In [tex]\rm FeO[/tex]: In the compound, oxygen is in group 16 and has a charge of -2, the iron ion must have a charge of +2 to balance the charges and make the compound neutral.

In [tex]\rm Fe_2O_3[/tex]: In the compound, oxygen is in group 16 and has a charge of -2, the three oxygen atoms in [tex]\rm Fe_2O_3[/tex] contribute to a total charge of -6. To make the compound neutral, the two iron ions must have a total charge of +6. Therefore, each iron ion must have a charge of +3 to balance the charges and make the compound neutral.

Therefore, Fe ion has a charge of +2 in the compound [tex]\rm FeO[/tex] and has a charge of +3 in the compound [tex]\rm Fe_2O_3[/tex].

Answer:

Mole

Explanation:

In solids, amount of substance is given by;

n = mass/molar mass

n will have a unit of mole

However, in liquids, amount of substance is;

n = concentration × volume

Again, n will be in mole

Thus, the SI unit that represents the amount of substance is mole

Answer:

2.1 atm

Explanation:

We are given the following variables to work with:

Initial pressure (P1): 2.5 atm

Initial temperature (T1): 320 K

Final temperature (T2): 273 K

Constant volume: 7.0 L

We are asked to find the final pressure (P2). Since volume is constant, we want to choose a gas law equation that relates initial pressure and temperature to final pressure and temperature. Gay-Lussac's law does this:

[tex]\frac{P_{1}}{T_1} =\frac{P_{2}}{T_2} \\[/tex]

We can rearrange the law algebraically to solve for [tex]P_{2}[/tex].

[tex]{P_{2}} =\frac{(T_2)(P_{1} )}{T_1} \\[/tex]

Substitute your known variables and solve:

[tex]P_2 = \frac{273K(2.5atm)}{320K} = 2.1 atm[/tex]

1s2  2s2  2p6  3s2  3p6  3d10 4s2  4p6  4d10

Explanation:

To write the configuration for the Silver and the Silver ion, first we need to write the electron configuration for just Silver (Ag).  We first need to find the number of electrons for the Ag atom (there are 47 electrons) using the Periodic Table.   When we write the configuration, we'll put all 47

Either way,  the Silver  electron configuration will be 1s2  2s2  2p6  3s2  3p6  3d10 4s2  4p6  4d10  5s1    

Note that when writing the electron configuration for an atom like Ag and Ag+, the 4d is usually written before the 5s.   Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written (see below for an explanation why).

For the Ag+, called the Silver ion,  we remove one electron from 5s2 leaving us with:

1s2  2s2  2p6  3s2  3p6  3d10 4s2  4p6  4d10

Answer:

3(NH4)2S + 2AlCl3 → 6NH4Cl + Al2S3

Explanation:

Firstly, ammonium sulfide has a chemical formula of (NH4)2S while aluminum chloride has a chemical formula of AlCl3. These two chemical substances react as follows:

(NH4)2S + AlCl3 → NH4Cl + Al2S3

This chemical equation is however, unbalanced. To balance the chemical equation, one has to ensure that the atoms of each element on both the reactant and product side equates with one another.

If we carefully observe each atom on both the reactants and product side, we will have the following balanced equation:

3(NH4)2S + 2AlCl3 → 6NH4Cl + Al2S3

That is;

- 6 moles of N and Cl on both sides

- 24 moles of H on both sides

- 3 moles of S on both sides

- 2 moles of Al on both sides

Answer:

Explanation:

Since salt is composed of two ions Na+ and Cl- it will attract to the opposite poles of the water and form a ion-dipole bond. This will cause the phenomenon freezing point depression where as the name states it will take a lower tempertature to freeze it. So instead of freezing at 0 degrees c it will freeze at a negative 2 or so on.

The salt ions end up slowing the growth of ice as the water molecules re-freeze.

Freezing point depression can be defined as the decreasing of the freezing point of pure solvents upon the addition of different kinds of solutes.

Depression in the freezing point can be defined as a colligative property that is proportional to the molality of the solution.

As liquid water gets colder and colder, the motions of water molecules become slower and slower. When salt is added to water, the saltwater solution is composed of both water molecules and dissolved salt ions.

As a result, salt ions can easily replace some of the water molecules. Saltwater freezes more slowly than pure water due to many of the water molecules would be "crashing" into the ice's surface in pure water and are replaced by salt ions.

Therefore, the salt water will freeze at a lower temperature than the pure water.

Answer:

This is not a chemical change

Explanation:

The dark green solution mixed with the water, but the water is still water. There were no bubbles, smell, temperature change, or any other signs of a chemical change

Have a great day!

A student mixes a dark green solution with water, and the result is pale green. This is a physical change.

Composition distinguishes a physical change from a chemical change. A physical change is a difference inside the look, smell, or straightforward presentation of a material sample without the need for a change in composition, whereas a chemical change alters the makeup of the substances in issue.

Despite the fact that we refer to them as physical "reactions," nothing is actually changing. A change in the substance in question's elemental composition is necessary for a reaction to occur. So, from now on, we will simply refer to bodily "reactions" as physical changes. A student mixes a dark green solution with water, and the result is pale green. This is a physical change.

Therefore, a student mixes a dark green solution with water, and the result is pale green. This is a physical change.

Answer: The partial pressure of the dry gas is 599.8 torr

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

[tex]p_{total}=p_{dry gas}+p_{H_2O}[/tex]

Given : [tex]p_{total}[/tex] =total pressure of gases = 642 torr

[tex]p_{dry gas}[/tex] = partial pressure of dry gas = ?

[tex]p_{H_2O}[/tex] = partial pressure of water = 42.2 torr

putting in the values we get:

[tex]642torr=p_{\text {dry gas}}+42.2torr[/tex]  

[tex]p_{\text {dry gas}}=599.8torr[/tex]

Thus the partial pressure of the dry gas is 599.8 torr
