Mole fraction and Partial pressure can be calculated from the expression of mole and Ideal gas law.
Ideal gases are defined as the theoretical gasses that can be used to model the behavior of real gasses. In order for it to be considered ideal, individual gaseous particles must both not attract or repel one another and also not have any volume. The expression for ideal gas law is,
PV = n RT
Take an example, if a 6.000L tank at 19.2°C is filled with 18.0g of carbon monoxide gas and 10.6g of chlorine pentafluoride gas.
mole CO = 18/28 = 0.6428
mole ClF5 = 10.6/130.445 = 0.081260
then
mole total = 0.081260+0.6428 = 0.72406 mole
PV = n RT
P = n RT/V = (0.72406) (0.082) (19.2+273) / (6) = 2.89146 atm.
mole fraction CO = 0.6428 /0.72406 = 0.8877
Partial pressure of CO = 0.8877 *2.89146 = 2.5667 atm.
mole fraction CF5 = 1-0.8877 = 0.1123
Partial pressure of CF5 = 0.1123*2.89146 = 0.32471 atm.

COOH Hc N=N; CH3
Methyl esters are created when carboxylic acids and diazomethane interact. Diazomethane is used to create methyl esters and has a high degree of reactivity.
Diazomethane reacts swiftly and extremely effectively, producing just N2 as a byproduct, making it an appealing alkylating agent for carboxylic and phenols (Black, 1983). As it responds, its inherent yellow color releases, automatically indicating the status of the reaction. Methyl esters are created when carboxylic acids and diazomethane interact. Diazomethane is created in-situ and then interacted with the carboxyl group right away to create the methyl ester due to its high reactivity. Diazomethane has mostly been used to transform carboxylic acids into esters (diazoalkales) that may be examined using GC/MS or HPLC-MS. In etherate solutions, methyl esters can be produced at room temperature quickly, thoroughly, and quantitatively.

what volume of 0.162 mna3po4 solution is necessary to completely react with 91.4 ml of 0.104 m cacl2 ?
The volume of 0.162 mna3po4 solution is necessary to completely react with 91.4 ml of 0.104 m cacl2 is 0.137 L
To determine the volume of 0.162 M Na3PO4 solution that is necessary to completely react with 91.4 mL of 0.104 M CaCl2, you can use the concept of stoichiometry..
The chemical reaction between Na3PO4 and CaCl2 can be represented by the following balanced chemical equation:
3 Na3PO4 + 2 CaCl2 -> Ca3(PO4)2 + 6 NaCl
First, you need to convert the volumes of the solutions to moles using the molarities and the volume/molarity formula:
moles Na3PO4 = (0.162 M) * (91.4 mL / 1000 mL/L) = 0.0150 moles
moles CaCl2 = (0.104 M) * (91.4 mL / 1000 mL/L) = 0.0095 moles
Next, use the molar ratios in the balanced chemical equation to determine the volume of Na3PO4 solution that is necessary to react with 0.0095 moles of CaCl2:
(Volume Na3PO4 / 3) = (Volume CaCl2 / 2)
Solving for the volume of Na3PO4, you get:
Volume Na3PO4 = (3 / 2) * (Volume CaCl2)
Plugging in the values, you get:
Volume Na3PO4 = (3 / 2) * (91.4 mL / 1000 mL/L)
Solving, you get:
Volume Na3PO4 = 0.137 L
Therefore, the volume of 0.162 M Na3PO4 solution that is necessary to completely react with 91.4 mL of 0.104 M CaCl2 is approximately 0.137 L.

How does transfer of thermal energy by radiation differ from convection and conduction?
Radiation is different from convection and conduction.
Heat transfer is the transport of heat from an area with higher heat content to one of lower heat content. When all of the components of the system are in thermal equilibrium, or when everything is at the same temperature, heat transfer ceases.
Because radiation transfers heat through light instead of a medium, it differs from convection and conduction. Heat is transported during convection through air or water currents. Conduction happens when two materials come into direct contact, like when a pan touches a heat source directly. However, radiation is the transfer of heat using light. This is how heat from the Sun reaches the Earth. This kind of heat transfer enables the transport of heat from space to Earth without the need for a medium.

The alkali metals, found in group 1 of the periodic table, are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they readily lose that one electron to form ionic bonds with other elements. Sodium (na) is an alkali metal that bonds with chlorine (cl), a halogen, to form table salt (nacl). Based on what the periodic table can tell you about these two elements, explain how and why they bond to form nacl.
Answer:
The periodic table is a useful tool for understanding the properties of elements and predicting how they will interact with each other. The alkali metals, including sodium, are located in group 1 of the periodic table. These elements have only one electron in their outermost shell, which makes them very reactive. They readily lose this outer electron to form an ion with a positive charge, which is called a cation.
Chlorine, on the other hand, is a halogen located in group 17 of the periodic table. Halogens have seven electrons in their outermost shell, which makes them highly reactive. They readily gain an electron to form an ion with a negative charge, which is called an anion.
When sodium and chlorine interact, they form an ionic bond to create the compound sodium chloride, or table salt. In this process, sodium loses its outer electron to form a sodium cation, and chlorine gains an electron to form a chlorine anion. The positive sodium cation is then attracted to the negative chlorine anion, forming an ionic bond. This bond is strong enough to hold the two ions together, creating a stable compound.
Therefore, sodium and chlorine bond to form table salt because they have the opposite charges and opposite reactivities that are necessary to form an ionic bond. The periodic table can help us understand this bonding process by providing information about the number of electrons in the outermost shell of each element, which determines their reactivity and ability to form ions.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, in below given ways, periodic table helps in explaining the reason of bonding.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.
Because sodium and chlorine have the opposing charges and reactivities required to create an ionic bond, they bind to make table salt. The periodic table can help us comprehend this bonding process by revealing the amount of electrons in each element's outermost shell, which governs their reactivity and capacity to generate ions.
Therefore, in above ways, periodic table helps in explaining the reason of bonding.

What is displacement reaction?Displacement reaction is a type of reaction in which one or two group from the reactants displaces by other groups. There are both single displacement and double displacement.
In single displacement reaction, only one group is displaced. Whereas, in double displacement reactions, two groups are displaced each other between reactants.
In the given reaction, the iodine atom and sulphide group are displacing as written in the equation.

according to the building-up principle or aufbau principle, which subshell is typically filled next after the 6s subshell?
Aufbau's principle states that an electron in an atom is filled according to the energy of orbitals, orbital with minimum energy is first filled, and so on.
so the order of filling of electrons in orbitals are 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p 8s.
so, the 4f subshell is filled after the complete filling of electrons in 6s.

which of the following has the lowest conductivity? a. 0.1 m cuso4 b. 0.1 m koh c. 0.1 m bacl2 d. 0.1 m hf e. 0.1 m hno3
The following has the lowest conductivity are the bacl2 that is 0.1 m as bacl2 is not good electrolyte.
Therefore BaCl2·2H2O is a great selec- tion for growing a polymer electrolyte in addition to for right ionic conductivity results.The molar conductivities at countless dilution of barium chloride, sulphuric acid and hydrochloric acid are 280, 860 and 426 S cm2 mol–1 respectively.
BaCl2 can not behavior energy in fused kingdom due to the fact charged debris can not flow in the crystal. BaCL2 is less in conductivity as it has not any of the conductive character and thus cannot definitely says about the conductive.
