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.

An object has a mass of 4 grams and a volume of 2 cm3. What is the density of the object
Answer:
The answer is 2.0 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 4 g
volume = 2 cm³
We have
[tex]density = \frac{4}{2} \\ [/tex]
We have the final answer as
2.0 g/cm³Hope this helps you
Answer:
D = 2 g/cm³
Explanation:
Density = mass over volume
D= m/v
Step 1: Define
m= 4 grams
v= 2 cm³
Step 2: Substitute and Evaluate
D= 4 g/2 cm³
D= 2 g/cm³

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.Describe the main differences beA human cell has 46 chromosomes.

Answer:
At the end of meiosis, there are four cells, each with 23 chromosomes, for a total of 92 chromosomes split between the four cells.
Explanation:
During meiosis, a diploid cell (46 chromosomes) replicates its DNA (making 92 chromosomes) then undergoes two cell divisions to generate four haploid cells (23 chromosomes).
These haploid cells are the gametes which, during fertilization, fuse to become a zygote with 46 chromosomes.

Answer:
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.

Choose the best statement of the octet rule from those listed below atoms lose 8 electrons to become valent atoms lose 8 electrons to become valent, atoms want 8 valence electrons atoms want 8 valence electrons atoms tend to react until they have 8 valence electrons atoms tend to react until they have 8 valence electrons, atoms tend to react in order to have the s2p4 configuration atoms tend to react in order to have the s2p4 configuration, atoms tend to react in order to gain 8 valence electrons atoms tend to react in order to gain 8 valence electrons
Answer:
atoms tend to react in order to gain 8 valence electrons
Explanation:
The octet rule describes the tendency of atoms of elements to react in order to have eight electrons in their valence shell. This is because having eight valence electrons confers stability to the atoms of these elements in the compounds they form.
The octet rule only does not apply to the transition elements or the inner transition elements as only the s and p electrons are involved. the electronic configuration in atoms having an octet is s²p⁶.
For example, sodium atom has one valence electron in its valence shell but a complete octet in the inner shell; it will react with chlorine atom which has seven valence electrons to form a stable compound, sodium chloride by donating its one valence electron in order to have an octet. Similarly, the chlorine atom will then have an octet by accepting the one electron from sodium atom.

A sample of aluminum has mass 26.98 g and has a density of
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.
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.

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.
