The name for SO2 is sulfur dioxide, where 'sulfur' is the name of the element and 'dioxide' indicates the presence of two oxygen atoms.

Explanation:

The name for SO2 is sulfur dioxide. This compound is a mixture of sulfur and oxygen, where the sulfur atom is joined by two oxygen atoms. Sulfur, being lower in the periodic table, comes first in the compound's name. Since there are two oxygen atoms, we use the prefix 'di-' to indicate the quantity, resulting in 'dioxide' when combined with the stem 'ox-' and the suffix '-ide'. Therefore, the complete chemical name is sulfur dioxide. It is important to note that sulfur forms another common compound with oxygen, which is SO3 or sulfur trioxide. Each of these compounds has distinct chemical and physical properties, necessitating unique names for accurate identification.

The weight of a satellite in a geosynchronous orbit is zero. This is because the satellite is in free fall, and the only force acting on it is the gravitational force of the Earth.

Weight is defined as the force of gravity acting on an object. In a geosynchronous orbit, the satellite is orbiting the Earth at the same rate that the Earth is rotating. This means that the satellite is always over the same spot on the equator. The satellite is also at an altitude of approximately 35,768 kilometers, which is very high above the Earth's surface.

At this altitude, the gravitational force of the Earth is much weaker than it is at sea level. In fact, it is only about 0.223 times the gravitational force at sea level.

In a geosynchronous orbit, a 2000 kg satellite experiences a weight of approximately 0.223 N. This significant reduction occurs due to the increased distance from the Earth's center.

The weight of an object, including a satellite, is the gravitational force it experiences due to Earth's gravity. In a geosynchronous orbit, a satellite orbits Earth at a distance where its orbital period matches the Earth's rotation period, typically around 35,786 kilometers above the equator.

The formula to calculate the gravitational force (weight) on the satellite is given by Newton's law of universal gravitation: F = G * (m1 * m2) / r²

where: G is the gravitational constant, approximately 6.67430 x10⁻¹¹ N(m/kg)²

m1 is the mass of the Earth, approximately 5.972 x 1024 kg

m2 is the mass of the satellite, 2000 kg in this case

r is the distance from the center of the Earth to the satellite, about 42,164 kilometers (radius of Earth + altitude of geosynchronous orbit)

Plugging in these values, we get: F = (6.67430 x 10⁻¹¹ N(m/kg)²) * (5.972 x 10²⁴ kg) * (2000 kg) / (4.2164 x 10⁷ m)²

Weight, of approximately 0.223 N.

The Aufbau Principle explains that electrons fill the lowest available energy levels in atomic orbitals before moving to higher levels. It helps determine the electron configuration of atoms, considering the periodic table, Hund's Rule, and the Pauli Exclusion Principle. This principle is essential for understanding atomic structure in chemistry.

The Aufbau Principle (German for “building up” principle) is a fundamental guideline in chemistry used to determine the electron configuration of an atom. It states that electrons fill atomic orbitals of the lowest available energy levels before occupying higher energy levels. In other words, the 1s subshell is filled before the 2s subshell, and the 2s subshell is filled before the 2p subshell, and so on.

This principle helps in constructing the electron configuration of an element by building it up step-by-step through the periodic table. For example, a carbon (atomic number 6) atom has an electron configuration of 1s2 2s2 2p2, which means it has filled the 1s subshell, then the 2s subshell, and finally partially filled the 2p subshell with two electrons.

Additionally, other rules like Hund's Rule and the Pauli Exclusion Principle work alongside the Aufbau Principle to determine the unique arrangement of electrons within orbitals. Hund's Rule states that electrons must occupy every orbital singly before any orbital is doubly occupied, and the Pauli Exclusion Principle asserts that no two electrons can have the same set of quantum numbers.

Utilizing these principles, students can accurately determine the ground-state electron configurations of atoms across the periodic table.

To find the molecular formula from the empirical formula, multiply each subscript in the empirical formula by the number of empirical formula units per molecule. This number can be obtained by dividing the molecular mass by the empirical formula mass.

The molecular formula is derived from the empirical formula by multiplying each of its subscripts by n, which represents the number of empirical formula units per molecule. To find the value of n, you need to compare the molecular or molar mass of the compound to its empirical formula mass. Divide the molecular mass by the empirical formula mass to determine n. Then, multiply each subscript in the empirical formula by n to obtain the molecular formula.

Final answer:

Joseph John Thomson discovered the electron, a fundamental negatively charged particle, developing the plum pudding model of the atom and earning a Nobel Prize for his contributions to physics.

Explanation:

British physicist Joseph John Thomson was the first to identify the electron, a negatively charged particle. In 1897, Thomson conducted groundbreaking experiments with cathode rays, proving that they were composed of particles rather than waves, because of their negative electric charge. He achieved this through meticulous experiments sending a pure beam of these particles through crossed electric and magnetic fields and balancing the fields until there was no net deflection of the beam. This allowed him to calculate the charge-to-mass ratio of the electron, revealing that its mass was significantly smaller than any known atom - precisely 1837 times smaller. Thomson's work led to the development of the plum pudding model of the atom, in which the atom was imagined as a sphere of positive charge with electrons dispersed within it, similar to plums in a pudding. His pioneering work paved the way for our modern understanding of the atomic structure and for this, he was awarded the Nobel Prize in Physics in 1906.

Deviations from the idealized bond angle occur due to the presence of lone electron pairs on the central atom. For the molecules PF3 and SBr2, the bond angles deviate from the ideal angles because of the lone pairs on the central atoms. On the contrary, CS2 and CHCl3, with no lone pairs on the central atom, do not deviate.

In Chemistry, deviations from the idealized bond angle are typically observed in molecules where one or more of the central atoms possess lone electron pairs. These lone pairs keep more space causing the bond angles to be less than the ideal angles predicted by the VSEPR (Valence Shell Electron Pair Repulsion) model.

I just answered on my test. the answer is B.

The statement, that describes which must be true of Solution 2 that poured into Solution 1 with pH of 6.5 is "It is more acidic than Solution 1."

A solution's pH is a measure of its hydrogen ion concentration, which is a measure of its acidity. In other terms, pH is a scale that specifies the acidity or basicity of an aqueous solution.

The scale ranges from zero (the most acidic) to fourteen (the most basic). The pH scale above shows that pure water has a pH value of 7. That is, pH values less than 7 are acidic, while pH values greater than 7 are alkaline (basic). As a result, solution 2 is acidic and contains more hydrogen ions than solution 1, because an acidic solution has a pH value less than 7.

Hence the correct answer is more acidic than Solution 1.
