IUPAC name for BaSO3
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.

What suprising result is explained using this model
Answer:
B. A few positive particles bounced back because they were pushed away from the positive center.
Explanation:
The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.
This is the central theme of Rutherford's experiment on a thin gold foil.
In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost. He bombarded a thin gold foil with alpha particles. He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.what is the mass of 10 moles of helium
Answer:
The mass of 10 moles of helium is: 2.5

Question 3 (1 point)
Which of the following elements is the most electronegative: arsenic, phosphorus,
sulfur, or selenium?
selenium
arsenic
phosphorus
sulfur
Answer:
sulfur
Explanation:
From the given lists of elements, the one with the most electronegativity is Sulfur.
Electronegativity is of an element is a property that combines the ability of its atom to lose and gain electrons.
It is a measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.
Using the Pauling's electronegative table of elements;
Here are electronegativity values of the given elements;
selenium 2.4
arsenic 2.0
phosphorus 2.1
sulfur 2.5
We see that the value of sulfur is the highest.
Pedro is baking a cake for his experiment on chemical changes. He knows a chemical change will occur when he puts the cake mixture in the oven. He would like to know what will happen when the cake is removed from the oven. What prediction would you make for Pedro's experiment? A. The chemical changes occurred because the chemicals changed. B. The chemical changes occurred because there was a change in light energy. C. The fruit and the hamburgers were affected by an increase in heat energy. D.The fruit and the hamburgers were affected by a decrease in heat energy.
Answer:
A. The chemical changes occurred because the chemicals changed.
Explanation:
When baking a cake several chemical reactions occur that change the chemical composition of the ingredients used in baking. An ingredient like baking powder releases carbon dioxide when it undergoes a temperature change in the oven. A chemical change is supposed to change the form of a substance.
An endothermic reaction also occurs when the ingredients absorb heat energy to produce several changes. The firmness of the cake occurs because of the heat absorbed by the proteinous content of the egg.

How many atoms are in the following formula?
3Al2O3
Answer:
15 atoms total
Explanation:
2 Al atoms + 3 O atoms = 5 Al2O3 atoms
5 Al2O3 atoms * 3 = 15
another way to do it is:
2 Al atoms * 3 = 6 Al atoms
3 O atoms * 3 = 9 O atoms
6+9 =15 atoms total
The number of atoms in the given 3Al₂O₃ is 15 atoms.
What are atoms?Atoms are the smallest unit of every matter. It contains charged particles present inside the atoms. They are electrons, protons, and neutrons. Atoms are of four types, description, isotopes, radioactive, and ions.
These atoms are the ions, that are charged, and the charged ions make bonds with each other to form compounds. Aluminum oxide is a compound that is formed by combining aluminum and oxygen atoms.
The compound is 3Al₂O₃
This means there are three moles of aluminum, and three moles of oxygen.
2 Al atoms + 3 O atoms = 5 Al₂O₃ atoms
5 Al₂O₃ atoms x 3 = 15
The elaborative way is:
2 Al atoms x 3 = 6 Al atoms
3 O atoms x 3 = 9 O atoms
6 + 9 =15 atoms total
Thus, the number of atoms is 15 atoms.

If carbon monoxide (CO) leaked into your home, would you predict that if would float to the
top of the room or stay near the floor? Answer the same question for carbon dioxide (CO2),
would it float or sink?
Answer: It will sink
Explanation:
To solve this we must be knowing each and every concept related to carbon monoxide. Therefore, carbon monoxide float to the top of the room.
What is carbon monoxide?When the carbon in fuels burns inefficiently, a toxic gas known as carbon monoxide is created. It is emitted both naturally—from forest fires or volcanic eruptions, for example—and artificially—through procedures. It is lighter than the air.
By attaching to and removing oxygen from myoglobin, carbon monoxide reduces the oxygen storage capacity in muscle cells, which is another way it upsets the body's processes. If carbon monoxide (CO) leaked into your home, carbon monoxide float to the top of the room. Numerous manufacturing and medicinal items employ carbon monoxide.
Therefore, carbon monoxide float to the top of the room.

Not all protists use flagella or cilia to move. Give an example of another way protists move and identify the type of protist that uses that mode of movement.
Answer: One of the most striking features of many protist species is the presence of some type of locomotory organelle, easily visible under a light microscope. A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively. (Those organelles give their names to informal groups—flagellates and ciliates—of protists.) A lesser number of protists employ pseudopodia. Those same organelles may be used in feeding as well.

1. Solid Definition: firm and stable in shape; not liquid or fluid.
Example: A hard kitchen countertop.
2. Crystalline Solid Definition: Crystalline solids consist of atoms, ions and molecules arranged in definite and repeating three-dimensional patterns in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Example: Salt, diamonds
3. Amorphous Solid Definition: an amorphous or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal.
Example: rubber, plastic, and gels
4. Liquid Definition: A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a constant volume independent of pressure. As such, it is one of the four fundamental states of matter, and is the only state with a definite volume but no fixed shape.
Example: Water, juice, rain
5. Surface Tension Definition: the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
Example: Walking on water: Small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface.

2.70 g/cm3. Calculate volume to the correct number of significant
figures.
Answer:
9.99L
Explanation:
you can see the answer at the pic
Answer:
The volume of aluminum is 9.99 cm³.
Explanation:
Given data:
Mass of aluminum = 26.98 g
Density of aluminum = 2.70 g/cm³
Volume of aluminum = ?
Solution:
Formula:
d = m/v
now we will put the values in formula.
2.70 g/cm³ = 26.98 g / v
v = 26.98 g / 2.70 g/cm³
v = 9.99 cm³
Thus, the volume of aluminum is 9.99 cm³.
