Hope this helps!!
Please tell me if I have made a mistake!!
I enjoy learning from them:)
Answer:
0.32L
Explanation:
Use formula of V= wt/mm•M.
To get this information we need to first get the molar mass (mm).
mm:
K - 2 x 39.09
S - 1 x 32.06
K2S - 110.262 g/mol
Now we plug it back into the equation.
3.5g/ (110.262 g/mol) • (0.100M)
= 0.317 L of solution
To round to the correct number of siginficant figures the answer is.
= 0.32 L

if the atoms that share electrons have an unequal attraction for the electrons, the bond is called
Answer:
A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is no longer symmetrical.
Explanation:
What is held together by a metallic bond?
Answer:
metallic bond, force that holds atoms together in a metallic substance. The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together.
Explanation:
mass is the gravitational pull on the earth
-tru
-fals
plz help
Answer:
I believe the answer is false
Explanation:
Earth's gravity comes from all of its mass. All the mass makes a combined gravitational pull on all the mass in an object. If you were on a planet with less mass than Earth, you would weigh less than you do here. Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. Mass is not the gravitational pull on the earth.

Is this a male cat or female?
Explanation:
Lift the kitten's tail. The opening just under the tail is the anus. Below the anus is the genital opening which is round in males and is a vertical slit in females. In kittens of similar size, the distance between the anus and the genital opening is greater in the male than the female.
TW: use of inapropate words*
Answer:
not enough information to tell
Explanation:
One way you can tell this difference is the distance between the cat's genitals (organs seen on the outside of the body) and the anus. A male will have a much greater distance between the genitals and anus than females, 1/2 inch apart on a male kitten and over 1 inch apart on a male adult cat. However, if the two are almost adjacent on a kitten or less than 1/2 inch apart on an adult, it’s a female.

one liter of gas has a pressure of 150.00kPa at 25 degrees celcius. if the pressure increases to 600.kPa and the temperature to 100.0 degrees celcius, what would be the new volume of the gas
Answer:
0.313 liters
Explanation:
You want to use the Combined Gas Law Equation: (P1*V1)/(n1*T1)=(P2*V2)/(n2*T2). You then want to cross off things that don't change, so moles(n) in this example. Then convert the temperature to Kelvin (always), and solve algebraically.

Answer · 47 votes
The properties can be influenced by many factors. The most common are the shape of the object, the lighting where the object is located, the environment (colors, shapes, density of other objects, etc.), and the viewing angle of the observer.
pls answer thisss it's due today
Answer:
1.correct
3.correct
Explanation:
pls mark me as brainliest
Answer:
I believe A is the correct answer.
Explanation:
I note that another response includes C. as another correct answer. It is possible, but it depends on what is meant by "fixed shape." I interpret "fixed shape" as the collection of the gases forming a fixed shape on their own. Gases fill the container they are in (be it a flask, room, or a planet, so they have a fixed shape by that definition. But a primary definition of gases is that that take on the shape of their container, not a shape of their own.
A. is correct because perfect gases have no interactions (AKA the Ideal Gas Laws). They may have interactions, and often do, but they are weak. That's why the ideal gas laws are a good first approximation to how gases change volume based on temperature and pressure.
10 facts about “molecules”
Answer:
Explanation:
A perfect diamond is a single molecule made of carbon atoms.
DNA is a super long molecule that has information uniquely describing every human being.
When two or more atoms chemically bond together, they form a molecule.
They are very small in size.
They have space between them.
They are in constant random motion.
molecules move when Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
In 1926, French physicist Jean Perrin received the Nobel Prize in physics for proving, conclusively, the existence of molecules.
Molecules can exist in free state because they are very stable.
The smallest particle of a compound capable of existing on its own is a Molecule-not a atom.
In which of the following reactions is chlorine (Cl) oxidized? Br2 2Cl⒠→ Cl2 2Br⒠Cl2 2e⒠→ 2Cl⒠2ClO3⒠12H → Cl2 6H2O 2Na Cl2 → 2NaCl.
The reaction in which Cl has been oxidized is [tex]\rm Br_2\;+\;2\;Cl^-\;\rightarrow\;Cl_2\;+\;2\;Br^-[/tex]. Thus, option A is correct.
In a reaction, the oxidation has been defined as the loss of electrons by the atom, while reduction has been depicted as the gain of electrons.
The loss of electrons imparts a positive charge to the atom, while the gain of electrons imparts a negative charge to the atom.
In the following reactions, the Cl has been given as:
[tex]\rm Br_2\;+\;2\;Cl^-\;\rightarrow\;Cl_2\;+\;2\;Br^-[/tex]The chlorine has loses the electron and is converted to diatomic molecule. Thus, the Cl has been oxidized. The oxidation state of Cl has also been increased from -1 to 0.
[tex]\rm Cl_2\;+\;2\;e^-\;\rightarrow\;2\;Cl^-[/tex]The chlorine gains 2 electrons in the reaction and has been reduced.
[tex]\rm 2\;ClO_3^-\;+\;12\;H^+\;\rightarrow\;Cl_2\;+6\;H_2O[/tex]There has been no change in the oxidation state of chlorine. Thus, Cl has not been oxidized.
[tex]\rm 2\;Na\;+\;Cl_2\;\rightarrow\;2\;NaCl[/tex]The chlorine gains electron and has been converted to the Cl ion. With the gain of electrons, Cl has been reduced.
The reaction in which Cl has been oxidized is [tex]\rm Br_2\;+\;2\;Cl^-\;\rightarrow\;Cl_2\;+\;2\;Br^-[/tex]. Thus, option A is correct.

a hypothesis is a prediction based on a theory. If the Hypothesis comes true the theory is more accepted.
A scientific theory differs from a scientific fact or scientific law in that a theory explains "why" or "how": a fact is a simple, basic observation, whereas a law is a statement (often a mathematical equation) about a relationship between facts.

As the ionic compound increases in
complexity, the melting point
A. increases
B. decreases
C. stays the same
Given what we know, we can confirm that as an ionic compound grows more complex, its melting point will increase.
What is an Ionic compound?An ionic compound is one in which atoms of elements share electrons between them to form compounds.These shared electrons generate powerful electrostatic forces that we refer to as ionic bonds. Electrostatic forces cause an increase in the melting point of a compound. As a compound grows more complex and adds more elements to its composition, it will gain new electrostatic forces, and thus increase its melting point.Therefore, as an ionic compound grows more complex, its melting point will increase due to the increasing number of strong electrostatic forces present in the compound.
