A substance that alters the rate of a chemical reaction without being permanently changed by the reaction is known as a catalyst.

Catalysts are substances that accelerate chemical reactions without being consumed or transformed by them.Catalysts work by reducing the activation energy required for a chemical reaction to take place. The activation energy is the minimum energy required for reactant molecules to react and transform into product molecules. Catalysts provide an alternative reaction pathway that involves a lower activation energy than the uncatalyzed reaction.

Because the catalyst isn't used up in the reaction, it can be recovered and reused.Catalysts can be classified into two categories: homogeneous and heterogeneous. A homogeneous catalyst is a catalyst that is present in the same phase as the reactants. A heterogeneous catalyst is a catalyst that is present in a different phase than the reactants. For example, a solid catalyst can be used to speed up a gaseous or liquid reaction.

Catalysts are used in a variety of applications, including the production of chemicals, pharmaceuticals, and fuels. They are also used to clean up industrial pollutants and to convert biomass into useful products. As a result, catalysts play an essential role in modern chemistry and industry.

The organic product formed when 1−hexyne is treated with H₂O, H₂SO₄, and HgSO₄ will be 2-hexanone (structure attached).

This reaction is an example of an oxymercuration reaction of the organic product 1−hexyne.

Oxymercuration is shown in three steps to the right. The nucleophilic double bond attacks the mercury ion, releasing an acetoxy group. The mercury ion's electron pair attacks carbon on the double bond, generating a positive-charged mercuronium ion. Mercury's dxz and 6s orbitals give electrons to the double bond's lowest unoccupied molecular orbitals.

In the second stage, the nucleophilic H₂O attacks the highly modified carbon, freeing its mercury-bonding electrons. Electrons neutralize mercury ions by collapsing. Water molecules have positive-charged oxygen.

In the third stage, the negatively charged acetoxy ion released in the first step attacks the hydrogen of the water group, generating the waste product HOAc. The two electrons in the oxygen-hydrogen link collapse into oxygen, neutralizing its charge and forming alcohol.

The atom with the lowest first-ionization energy would be the one with the electron configuration: 1s2 2s1, as it has a partially filled valence shell in the 2s orbital.

Ionization energy is the energy required to remove an electron from an atom or ion in the gaseous state. This energy is frequently measured in terms of an ionization potential or ionization energy, which is the minimum energy required to remove an electron from a neutral atom or molecule to a point where the ion's charge is zero.

The first-ionization energy is the energy required to remove the outermost (valence) electron from an atom in the gas phase. The lower the first-ionization energy, the easier it is to remove the electron.

Out of the given ground-state electron configurations, the atom with the lowest first-ionization energy would be the one with the electron configuration that has a partially filled valence shell, as it requires less energy to remove an electron from a partially filled orbital compared to a filled orbital..

The electron configurations of the other options are:

1s2 2s2 2p2: This configuration has a filled valence shell, so it would require more energy to remove an electron.

1s2 2s2 2p6: This configuration has a filled valence shell, so it would also require more energy to remove an electron.

1s2 2s2 2p6 3s1: This configuration has a partially filled valence shell, but the electron is in a higher energy level (3s) compared to the first option, so it would require more energy to remove an electron.

The number of deciliters in 2.2 kL or kiloliters is 22,000.

Deciliters and kiloliters are units of measurement of volume. The SI unit of the volume is Liters.

Since the deciliter is a smaller unit than kiloliters that is why their conversion is done through multiplication by the appropriate number by the exponent of 10. To convert kiloliters into deciliters we have to convert it by multiplying the given number by \(10^5\).

These conversion units can be described by the formula \(n_1u_1=n_2u_2\) where n is the magnitude and u is the unit

Number of deciliters in 1 kL = 10,000

Thus, the number of deciliters in 2.2 kL = 2.2 * 10,000

The Pressure  inside the container 5.56 atm

Explanation:

Given that:

the mass of CO2 = 50.0g

molar mass of CO2= 44 g/mol

So; the number of moles of CO2 = mass/molar mass

= 50.0 g/44 g/mol

= 1.1364 mol

Volume of the container = 5.0 L

Temperature = 25°C = ( 25+273.15)K = 298.15 K

universal gas constant R  = 0.08206 L atm mol⁻¹ K⁻¹

Using Ideal Gas Equation PV = nRT

P = nRT/V

P = (1.1364 × 0.08206  ×  298.15) / 5.0

P =  27.80337718/ 5.0

P = 5.560675436 atm

The evaporation of water from your skin is an example of an endothermic reaction because heat is lost from the body as the water evaporates from the skin.

Based on the heat changes that occur in reaction, reactions can be classified into two types;

Exothermic reactions are reactions in which the heat content of the reactants is greater than the heat content of the products. Hence, heat is given out during the reaction. An example is the dissolution of acids in water.

Endothermic reactions are reactions in which the heat content of the reactants is less than the heat content of the products. Hence, heat is absorbed during the reaction. An example is the evaporation of water from the skin.

Other types of endothermic reactions are the melting of ice and thermal decomposition.

The number of moles of gas added to the container is 6.11 mol.

We know that for a fixed amount of gas, pressure and temperature are directly proportional to volume (Boyle's Law). This means if the pressure and temperature remain constant, then the ratio of the initial and final volume should be the same as the ratio of the initial and final number of moles of gas, given by Avogadro's Law.

Initial volume = 5.12 L, Initial moles of gas = 4.51 mol
Final volume = 12.1 L, Final moles of gas = x (unknown)
Using the Avogadro's Law formula:

Initial moles / Initial volume = Final moles / Final volume
4.51 mol / 5.12 L = x mol / 12.1 L

Solving for x:

x = (4.51 mol / 5.12 L) * 12.1 L
x = 10.62 mol

Therefore, the final number of moles of gas in the container is 10.62 mol. The number of moles of gas added to the container is the difference between the final and initial moles of gas:

Moles added = 10.62 mol - 4.51 mol
Moles added = 6.11 mol

However, we are asked to find the number of moles of gas added to the container from the initial volume to the final volume. Therefore, we only need to calculate the number of moles added beyond the initial 4.51 mol.

Moles added = Final moles - Initial moles
Moles added = 10.62 mol - 4.51 mol
Moles added = 6.11 mol.
