To convert each percentage of abundance to a decimal, divide it by 100. Add the atomic mass of the isotope to this value. The atomic mass is obtained by averaging the atomic masses of each isotope.

To calculate the weighted average, we must take each isotope's % natural abundance into effect. The weighted mean of the atomic masses of an element's naturally occurring isotopes serves as the element's atomic mass.

The proportion of atoms with a particular atomic mass that can be found in a found naturally sample of an element is known as the relative abundance of an isotope.

Isotopes are atoms of the same element that have differing mass numbers but the same atomic number. Example: Protium (Z=1, A=1), Deuterium (Z=1, A=2), and Tritium (Z=1, A=3) are hydrogen isotopes.

Atom is defined as the smallest particle of matter and is composed of subatomic particles protons, Neutrons and Electrons. Protons have a positive charge and Neutrons have neutral charge; they are concentrated at the Nucleus. Electrons are electrically negative and spin around the Nucleus in specialized pathways called Orbits or shells.

The Atom is electrically neutral due to equal number of Protons and Electrons. Nucleus has a positive charge so negatively charged electrons are attracted to the positive core or Nucleus. The number of electrons in orbit is in increasing order of energy level. The orbits near the nucleus have less number of electrons and this is called the Principal Quantum Number.

From the data in the table, it can be seen that the rate of reaction is independent of the concentration of O3, meaning that the reaction order with respect to O3 is 0. The value of k is 0.472 mol/(L.s)-1

On the other hand, the rate of reaction is directly proportional to the concentration of SO2, meaning that the reaction order with respect to SO2 is 1.

b. Based on this information, the rate law for the reaction is:

rate = k[SO2].

c. To determine the value of the rate constant, we can use the rate data for one set of conditions. For example, when [SO2] = 0.25 mol/L and [O3] = 0.40 mol/L, the initial rate is 0.118 mol/(L.s). Plugging these values into the rate law, we get:

0.118 = k × 0.25.

Solving for k, we find that the value of k is 0.472 mol/(L.s)-1. The units of k are (L.s)-1.

boron atom has 5 protons and 5 electrons. Its average atomic mass is 10.81.

Boron's atomic number is 5 because it has 5 protons in its nucleus. The number of protons in an atom's nucleus is what determines the element's atomic number.

What is nucleus?

Nucleus is the central core of an atom, consisting of protons and neutrons. It is the heaviest and most important part of the atom, as it contains most of the atom's mass and positive charge. The number of protons in the nucleus determines the element, while the number of neutrons determines the isotope. The nucleus is held together by a strong nuclear force and can be found in the center of the atom. It is surrounded by a cloud of electrons that orbit it at a distance. The nucleus is the key to understanding how chemical reactions occur, as its composition is what determines the type of atom.

The weather pattern that explains these events in Towns A and B is likely a temperature inversion.

This occurs when a layer of warm air is trapped above a layer of cold air, causing the warm air to stay close to the ground and the cold air to remain in the upper atmosphere. In this scenario, Town A would be experiencing the cold, rainy weather because it is located under the layer of cold air, while Town B would experience the warm, rainy weather because it is located above the layer of warm air. This type of weather pattern can last for several days and is caused by differences in air pressure and temperature.

The reason dissolving salt in water an endothermic process is because it requires the absorption of heat from the environment. This happens because the bonds between the salt ions and the water molecules are disrupted, and energy is needed to overcome these bonds and allow the salt ions to dissolve in the water.

Any thermodynamic process with an increase in the enthalpy H (or internal energy U) of the system is referred to as an endothermic reaction in thermochemistry (from the Greek v (endon) "inside" and -(therm) "hot, warm"). A closed system often transfers heat into itself during such a process by absorbing thermal energy from its surroundings.

As a result, an endothermic reaction typically results in a rise in the system's temperature and a fall in the environment's. It could involve a chemical reaction, such when ammonium nitrate (NH4NO3) is dissolved in water (H2O), or a physical action, like when ice cubes melt.

The number of moles of water that vaporized during the first five minutes would be 2.78 moles (50 g / 18 g/mol = 2.78 moles).

Moles are a kind of small mammal found in many parts of the world. They are burrowing animals, living underground in burrows and tunnels. They have adapted to life underground and have physical features that help them survive in this environment, such as small eyes and ears, short legs and strong claws. They feed mainly on grubs, worms, and other small invertebrates found underground. They also eat some plant material and occasionally small animals. Moles are solitary animals and live in small family groups. They play an important role in the ecosystem, aerating and fertilizing the soil.

In order to calculate the number of moles of water that vaporized during the first five minutes, we must first calculate the mass of water vaporized during the same time period. This can be done by subtracting the mass of water remaining in the beaker after five minutes from the initial mass of water in the beaker. Once the mass of water vaporized is determined, it can then be converted to moles using the equation mass (g) = moles x molar mass (g/mol).

Assuming the initial mass of water in the beaker was 100 g, and the mass of water remaining in the beaker after five minutes was 50 g, the mass of water vaporized during this time period would be 50 g. To convert this to moles, we would use the equation mass (g) = moles x molar mass (g/mol). Since the molar mass of water is 18 g/mol, the number of moles of water that vaporized during the first five minutes would be 2.78 moles (50 g / 18 g/mol = 2.78 moles).

The carbon dioxide was dissolved in the soft drink under high pressure. When the bottle was opened, the pressure inside the bottle dropped, causing the carbon dioxide to escape from the solution in the form of bubbles. Which was dissolved in the liquid under pressure. When the student opened the bottle, the pressure inside the bottle was released, causing the CO2 gas to escape from the liquid and form bubbles on the inside of the bottle.

The shorthand electron configuration of a potassium ion (K+) is [Ar] 4s1.

Electron configuration refers to the arrangement of electrons in an atom or ion. In a neutral atom, the number of electrons is equal to the number of protons, resulting in a neutral charge. However, in an ion, the number of electrons is not equal to the number of protons, resulting in a charge.

The shorthand electron configuration uses symbols from the periodic table to represent the elements, with electron configurations being abbreviated by using the noble gas symbol (in square brackets) that precedes the element in question in the periodic table. In this case, the noble gas symbol [Ar] represents Argon, and the electron configuration of K+ is then given as [Ar] 4s1, indicating that the electron configuration of potassium has lost one electron from its 4s orbital, leaving a single electron in the 4s orbital and a positive charge on the ion.

In more detailed terms, the electron configuration of a neutral potassium atom would be [Ar] 4s1 3d10, where the [Ar] represents the electron configuration of Argon (the preceding noble gas in the periodic table), and the 4s1 and 3d10 indicate the number of electrons in the 4s and 3d orbitals, respectively.

The electronegativity values of elements can be found on the periodic table and can be used to determine whether the bond is ionic or covalent.

The type of bond present in a molecule can be determined based on the electronegativity difference between the atoms that make up the bond. If the electronegativity difference between the atoms is large, then the bond is considered ionic. On the other hand, if the electronegativity difference is small, the bond is considered covalent. The electronegativity values of elements can be found on the periodic table.

For example, the elements present in sugar (C12H22O11) are carbon, hydrogen, and oxygen, with carbon having an electronegativity of 2.5, hydrogen of 2.2, and oxygen of 3.5. As the electronegativity difference between these elements is small, the bonds present in sugar are covalent.
