Your classmate says that the farther the two atoms are apart in a bond, the larger the dipole moment will be, this statement is correct.
What is bond ?An enduring attraction between atoms or ions known as a chemical bond is what allows molecules and crystals to form. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds.
Chemical bonds are formed when the atoms in a compound's molecule are brought together and kept together by a powerful combining force. Ionic and covalent bonds are the two different kinds of chemical bonding.
Atoms trade or exchange valence electrons to create bonds. The electrons at an atom's outermost energy level, known as valence electrons, have the potential to interact chemically. All chemical bonds are built on valence electrons.
Thus, the farther the two atoms are apart in a bond, the larger the dipole moment will be, this statement is correct.

The atomic mass of helium is the bottom number underneath its symbol. The atomic mass is 4.0026. Since helium only have 2 protons, then helium has 2 neutrons because you subtract the atomic number from the atomic mass to find the neutron count. The atomic number is the top number above "He". The atomic number of helium is 2 and it refers to the amount of protons.
ILL GIVE YOU BRIANLIEST! PLEASE HELP: Every compound is a molecule, but every molecule is not a compound. Why is this? Give an example with your answer.
Answer:
This is because some molecules contain only one chemical element, and a compound, by definition, contains 2 or more elements.
Explanation:
Consider molecular Hydrogen (H₂) as an example. It is a molecule, albeit very simple, because it is made up of multiple atoms (2 Hydrogen atoms, to be precise). It is not a compound, however, because it only contains one chemical element: Hydrogen.

Does this chemical equation demonstrate conservation of matter? (Yes or No) How do you know this? Li2CO3 + CO2 + H2O → 2LiHCO3
Answer:
No, it does not demonstrate conservation of matter because there are not the same number of atoms of the products and reactants. For example, the carbon dioxide and water reactants are not represented on the product side of the equation.

Why does the total mechanical energy stay the same as kinetic and potential energy change?
total mechanical energy is the sum of kinetic energy and potential energy so it will remain same always
Answer:
Explanation:
Because the kinetic and potential energy are constant. A good example of kinetic and potential energy are throwing a ball up. It leaves your hand with kinetic energy. When it reaches the top it doesn’t have any kinetic force but potential energy equal to the kinetic energy the ball had when you threw it up. And, when it comes back to your hand it has the same kinetic energy it had when it left your hand. Thus, the sum of the kinetic energy plus potential energy is a constant.
Make predictions about how changing the mass or speed of an object will change the object's kinetic energy.
Help, please science btw
Answer:
speed inscreases mass decrreases, but when no friciton mass dont matter
Explanation:
Mass does not affect speed directly, but it does affect how fast an object can change its speed by accelerating or decelerating. Objects with larger masses require more time for acceleration or deceleration compared to lighter objects. The law of inertia states that objects that are still remain still and that objects in motion remain in motion regardless of the object's mass.
In a bond between Na & Cl, which is considered the more-negative atom?
Answer:
Chlorine(Cl) is a bit more negative than Sodium(Na)
Explanation:
Cl has an electronegativity of 3.0
Na has an electronegativity of 1.0
Answer:
The bond between Na & CI is ionic. One atom will form a a negative ion and the other will form a positive ion. Sodium (Na) has 1 valence electron, so it will give it away in order to become stable (octet rule). Chlorine has 7 valence electrons. So when Na and Cl bond, chlorine will take sodium's 1 valence electron and become stable. Now both atoms are stable but each form a specific ion. Since sodium lost its electron, It now has an imbalance where there are more protons than neutrons. This makes the sodium atom a positively charged ion (Na+). Since chlorine gained an electron, it now has an inbalance where there are more electrons than protons. This makes the atom a negatively charged ion (Cl-)

Liquid water (H2O) is formed when two gases, hydrogen (H2) and oxygen (O2), react. Why are the properties of water different than those of the reactant gases?
Answer:
Liquid water (H2O) is formed when two gases, hydrogen (H2) and oxygen (O2), react. ... The difference in the properties of water can be attributed to physical changes to the hydrogen and oxygen atoms on a subatomic level. The properties of the gases are combined to give water its properties.

Lead has a density of 11.4 grams per mL. If I make a statue out of 3.78 grams of lead, what is the statues volume
Answer:
0.332mL
Explanation:
11.4g/mL is 11.4 for every one mL
11.4g / 1mL needs to be the same ratio as 3.78g to an unknown value, let's call it x.
11.4g/1mL = 3.78g/x
We cross multiply: 1*3.78 = 11.4*x
3.78 = 11.4x
Now isolate x by diving 11.4 on both sides: 0.331578974mL = x
In chemistry, we usually round to significant figures, so our answer would be 0.332mL

How many moles is 1.7 × 1023 atoms of Ne
Answer:
0.282 moles
Explanation
I assume you meant How many moles is 1.7 × 10^23 atoms of Ne?
1 mole is 6.02X10^23 .Avogados number=
(1.7X10^23)/(6.02X10^23)= 0.282 moles
Answer:
[tex]\boxed {\boxed {\sf 0.28 \ mol \ Ne}}[/tex]
Explanation:
We are asked to find how many moles are in 1.7×10²³ atoms of Ne or neon.
Atoms are converted to moles using Avogadro's Number or 6.022 ×10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. For this problem, the particles are atoms of neon.
We convert using dimensional analysis, so a conversion factor (using Avogadro's Number) must be set up.
[tex]\frac {6.022 \times 10^{23} \ atoms \ Ne}{ 1 \ mol \ Ne}[/tex]
We are converting 1.7×10²³ atoms of Ne to moles, so we multiply the ratio by this value.
[tex]1.7 \times 10^{23} \ atoms \ Ne *\frac {6.022 \times 10^{23} \ atoms \ Ne}{ 1 \ mol \ Ne}[/tex]
Flip the ratio so the units of atoms of neon cancel out.
[tex]1.7 \times 10^{23} \ atoms \ Ne *\frac { 1 \ mol \ Ne}{6.022 \times 10^{23} \ atoms \ Ne}[/tex]
[tex]1.7 \times 10^{23} *\frac { 1 \ mol \ Ne}{6.022 \times 10^{23} }[/tex]
[tex]\frac { 1.7 \times 10^{23}}{6.022 \times 10^{23} } \ mol \ Ne[/tex]
Divide.
[tex]0.2822982398 \ mol \ Ne[/tex]
The original measurement of atoms (1.7×10²³) has 2 significant figures (1 and 7). Our answer must also have 2 significant figures. For the number we found, that is the hundredth place.
The 2 in the thousandth place tells us to leave the 8 in the hundredth place.
[tex]0.28 \ mol \ Ne[/tex]
1.7×10²³ atoms of Neon are equal to approximately 0.28 moles of neon.

The monomers used to make sodium polyacrylate polymer chains acrylic acid (H₂C=CHCOOH) and its sodium salt (H₂C=CHCOONa) .
What are Monomers ?Monomers are small organic molecules that have the capability to bond to form larger molecules known as polymers.
The reaction between acrylic acid (H₂C=CHCOOH) and its sodium salt (H₂C=CHCOONa) produces sodium polyacrylate.
A long-chain copolymer made up of alternate units of acrylic acid and sodium acrylate is the result of this process.
Acrylic acid and sodium acrylate form a copolymer, which is a polymer made up of two distinct monomers.
