Answer:
Barium Sulfite
Explanation:
Barium Sulfite
The IUPAC name for BaSO₃ is barium sulfite.
"Ba" stands for barium, which is the chemical symbol for the element with atomic number 56. Barium is an alkaline earth metal and belongs to Group 2 of the periodic table.
"SO₃" stands for sulfite, which is a polyatomic ion composed of one sulfur atom (S) and three oxygen atoms (O). The chemical formula for the sulfite ion is SO₃²⁻. The sulfur atom in the sulfite ion has a +4 oxidation state.
When barium (Ba) reacts with the sulfite ion (SO₃²⁻), they combine to form barium sulfite (BaSO₃). The balanced chemical equation for the reaction is:
Ba²⁺ + SO₃²⁻ → BaSO₃
Barium sulfite is an ionic compound, where the Ba²⁺ ion and the SO₃²⁻ ion are held together by electrostatic attractions (ionic bonds). In its solid form, barium sulfite appears as a white crystalline powder.

How did Thomson's experiment change Dalton's atomic model?
A. Thomson discovered that atoms changed properties when put in
an electric field.
B. Thomson discovered that atoms did not rearrange when forming
compounds.
C. Thomson discovered that atoms of one kind of element could
have different masses.
D. Thomson discovered that the atom contained smaller particles
called electrons.
Answer:
D. thomson discovered that the atom contains smaller particles called electrons
Thomson discovered that the atom contained smaller particles called electrons. The correct option is D.
What is Dalton's atomic model?Dalton proposed that all matter is composed of tiny indivisible particles known as atoms, which he envisioned as "solid, massy, hard, impenetrable, movable particle(s)."
Thomson's experiment altered Dalton's atomic model by revealing the existence of smaller particles known as electrons within the atom.
The first part of his theory states that all matter is made up of indivisible atoms. According to the second part of the theory, all atoms of a given element have the same mass and properties.
One of Dalton's most important contributions is that it does not violate several fundamental laws of chemical combination, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.
Thus, the correct option is D.

Radio
Which has the highest frequency?
X-rays Visible
Microwave
WWW
Answer:
Radio waves
X-rays Visible
Explanation:
The wavelength of a wave is the difference between successive crests on a wave line. Waves with a very high wavelength have low energy.
Frequency is the number of waves that pass a point per unit of time. The higher the frequency, the higher a wave's energy.
From the given spectrum, wavelength increases from left to right. This puts radio waves as the wave with the longest wavelength. It is also right to say, it has the least energy. Also, frequency decrease from left to right. Gamma rays have the highest frequency in the spectrum. This is followed by x-rays.Answer:
Radio waves
X-rays Visible

1. Calculate the average atomic mass of iron if its abundance in nature is 15%-iron-55 and
85% iron-56
The average atomic mass of iron : 55.85 amu
Further explanationThe elements in nature have several types of isotopes
Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.
An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.
The 'amu' unit has now been replaced with a unit of 'u' only
Atomic mass is the average atomic mass of all its isotopes
atomic mass X = mass isotope 1 . % + mass isotope 2.% ...
The average atomic mass of iron
[tex]\tt =0.15\times 55+0.85\times 56\\\\=\boxed{\bold{55.85~amu}}[/tex]
The average atomic mass of iron : 55.85 amu
Calculation for average atomic mass:Isotopes are atoms whose atoms have the same number of protons while still having a different number of neutrons.
An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.
The 'amu' unit has now been replaced with a unit of 'u' only
Atomic mass is the average atomic mass of all its isotopes.
Atomic mass X = mass isotope 1 * Mas % + mass isotope 2* Mass %
The average atomic mass of iron:
=0.15 * 55 + 0.85 * 56
=55.85 amu
Thus, the average atomic mass of iron : 55.85 amu

Explanation:
A student combines two clear liquid chemicals together in a beaker. When the two chemicals are combined, bubbles are formed, the solution turns blue, and you can see flakes of something forming on the bottom of the beaker. Is this a physical or chemical change? Why?
Answer:
chemical change
Explanation:
A physical change is one that makes changes to the physical properties of matter. In many cases, the difference is usually reversible. Examples include boiling, melting, freezing, the magnetization of metals, etc.
A chemical change is one in which a new kind of matter is formed. It is usually accompanied by energy changes, i.e., the evolution or absorption of energy in the form of heat or light. This process is not easily reversible. Examples include; combustion, rusting of iron, precipitation, the souring of milk, etc.
From the question given, the combination of two clear liquid in a beaker which results to formation of bubbles and changes in coloration of the solution is a chemical change.
What purpose do neutrons serve in the nucleus ? What happens if there are too many or too few neutrons?
Answer:
These nuclei with different numbers of neurons are called isotopes
Answer:
neutrons' main function is to attract each other and keep the nucleus of an atom intact. a nucleus will become unstable if there are too many or too few neutrons in it.
Explanation:
too many= it will undergo beta decay (the neutrons will changes into proton)
too few= there will be an imbalance between forces which leads to nuclear imbalance

A student states that photosynthesis is conducted only in plant cells and that cellular respiration occurs only in animal cells. Tell whether the student is correct and why. In your response, be sure to describe both processes and the structures involved. Upload your answer below.
Answer:
This is correct
Explanation:
This is correct because for photosynthesis you need organelles such as chloroplasts, chloroplasts absorb light energy and convert it into usable energy for plants. Animal cells do not have chloroplasts/similar organelles so they can't absorb energy from the sun, Animal cells use mitochondria which takes energy from our food and breaks it down into usable energy(such as ATP) to be transported.

What is the mass obtained of Ag from the reaction of 3 moles of AgCl
Given= Zn + 2AgCl —> ZnCl2 + 2Ag
Answer:
323.7g
Explanation:
Given parameters:
Number of moles of AgCl = 3 moles
Unknown:
Mass of Ag = ?
Solution:
We solve this problem by working from the known to the unknown;
The known here is AgCl;
From the balanced equation:
Zn + 2AgCl → ZnCl₂ + 2Ag
2 moles of AgCl will produce 2 moles of Ag
3 moles of AgCl will produce 3 moles of Ag
The mass of Ag will be;
Mass of Ag = number of moles x molar mass
Molar mass of Ag = 107.9g/mol
Mass of Ag = 3 x 107.9 = 323.7g

During evaporation, what causes certain liquid molecules to become vapor molecules? A. Decreased fluidity A. Increased viscosity A. Decreased kinetic energy A. Increased kinetic energy.
Answer:
The answer is A. Decreased Fluidity
Explanation:
Taking the test on preformance matters
In evaporation, particles of liquids take energy in the form of sunlight from the surrounding and then convert into vapor phase. Increased kinetic energy causes certain liquid molecules to become vapor molecules.
What is evaporation?Evaporation is a physical process in which the water in liquid state converts to gaseous state at the temperature below its boiling point. Evaporation happens before the boiling process.
Evaporation causes cooling effect in the surrounding. During summer when water is kept in earthen pot water cools, this is because of the evaporation process.
Evaporation is affected by temperature. As the temperature increases, kinetic energy of liquid molecules also increases and hence the rate of evaporation increases.
Therefore, increased kinetic energy causes certain liquid molecules to become vapor molecules.
