Answer:
The strongest intermolecular force in sulfur dioxide is dipole-dipole forces.
Explanation:
The interparticle force in [tex]SO_{2}[/tex] (sulfur dioxide) is the dipole-dipole interaction.
What is dipole-dipole interaction?
Dipole-dipole interaction is a type of intermolecular force that occurs between polar molecules. Polar molecules have a permanent dipole moment, which means they have a partial positive charge on one end and a partial negative charge on the other end. This creates an electrostatic attraction between the partial charges of neighboring molecules. The stronger the dipole moment of a molecule, the stronger its dipole-dipole interaction will be with other polar molecules.
Dipole-dipole interactions are responsible for a variety of physical properties of substances, including their boiling and melting points. Substances with strong dipole-dipole interactions tend to have higher boiling and melting points than substances with weaker interactions. In addition, the strength of dipole-dipole interactions can affect solubility, as polar substances tend to dissolve better in other polar substances due to their ability to form dipole-dipole interactions.

How many grams are in 3.4 moles of Lead (IV) Sulfate (Pb(SO4)2)? ) Molar mass: 303.26 g/mol 131.0840
Answer:
1031.084g
Explanation:
n=m/M
m=n(M)
m = (3.4mol)(303.26g/mol)
1031.084g
Hope that helps
Answer:
1031.08
Explanation:
You start with 3.4 moles and you know that 6.022 x 10 ^ 23 = 1 mole( Avogadro's Number), so you just multiply those 2 numbers and the moles will cancel leaving you with grams of Lead Sulfate.

2) Imagine that a loudspeaker is producing quiet note with a low pitch
How will it’s viberation change
a) If the pitch of the note becomes higher?
b) If the note become louder
Answer:
Higher pitched sounds produce waves which are closer together than for lower pitched sounds. (Think of the slinky - if you produce waves rapidly they will travel quite close to each other, thus demonstrating a higher pitched sound.)
The pitch of a note will depend on a number of factors. One of these is the size of the vibrating object. On a glockenspiel or xylophone the high notes are made by the smaller bars. A smaller triangle or cymbal will make a relatively higher pitch note. On a stringed instrument such as a guitar or violin a thinner string will generally make a higher note, but also shortening the string by stopping it with the finger will produce a similar effect. On a set of pan pipes or a church organ it is the shorter pipes which make the higher notes when the air inside them vibrates.
Another factor which produces higher pitched notes is the tension within the vibrating object. A guitar string can be tuned to a higher pitch by adjusting the string tensioner. An elastic band can be stretched tighter and a drum skin can be tensioned to increase the pitch of the sound it produces.

Which neutral atom is isoelectronic with N-3?
The neutral atom is isoelectronic with N⁻³ is Neon (Ne).
Isoelectronic are those which have same number of electrons or we can say that same electronic structure.
For finding out that the species are isoelectronic , we just have to count there no. of electrons of atoms and if they have same no. of electron then they said to be isoelectronic species.
no. of electrons in Nitrogen N = 7 ( atomic no.)
no. of electrons in Nitride ion N⁻³ = 7 + 3 = 10
no. of electrons in Neon Ne = 10 ( atomic no. and neutral atom)
so, no. of electrons in Nitride ion N⁻³ = no. of electron in Neon Ne
this means , N⁻³ , Nitride ion is isoelectronic with Neon Ne.
Thus, The neutral atom is isoelectronic with N⁻³ is Neon (Ne).

A sample of tin (Cp = 0. 227 J/g•°C) is placed in a freezer. Its temperature decreases from 15. 0°C to â’10. 0°C as it releases 543 J of energy. What is the mass of the sample? Round your answer to three significant figures. G.
Taking into account the definition of calorimetry, the mass of the sample is 478.41 grams.
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
So, the equation that allows to calculate heat exchanges is:
Q = c× m× ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
Q= -543 J because the energy is releasesc= 0.227 [tex]\frac{J}{gC}[/tex]m= ?ΔT= Tfinal - Tinitial= 10 C - 15 C= -5 CReplacing:
-543 J= 0.227 [tex]\frac{J}{gC}[/tex]× m× (-5 C)
Solving:
[tex]m=\frac{-543 J}{0.227 \frac{J}{gC}x(-5 C)}[/tex]
m=478.41 grams

The molecular formula for a compound with a molar mass of 180.18g that contains 40.0% carbon, 6.7% hydrogen, and 53.3% oxygen by mass is
Answer:
C6H12O6
Explanation:
First you need to find the empirical formula by the percents that they're giving you. You assume that is 100 grams and if for example you have 40% of carbon you will have 40 grams of carbon.
1.Find the number of moles of each atom
C: 40g÷12g/mol= 3.33 mol
H: 6.7g÷1g/mol= 6.7 mol
O: 53.3g÷16g/mol= 3.33 mol
You divide all ratios by the minimum ratio and you obtain the empirical formula
CH2O
Since you're given the molar mass, you now have to find the molar mass of CH2O by adding the molar mass of each element present and repeated in the compound.
CH2O= 30g/mol
Now you know that the molar mass of the molecular formula we are looking for is 180.18 g/mol, and since the empirical formula is the molecular formula in its smaller ratio, by logic you can say that:
180.18g/mol ÷ 30g/mol= 6
So, you now know that the empirical formula is being multiplied by a factor of 6 to reach a compound with a molar mass of 180.18g/mol, so you multiply each subscript of the empirical formula by 6 obtaining:
C6H12O6
The compound of ammonium sulfate consists of two ions. NH4+ and SO42- both of which are polyatomic ions. a molecule of the compound consists of (one, two , or four) NH4+ ions and (one, two, or four) SO42- ions?
Answer:
Blank #1: Polyatomic
Blank #2: 2 (see explanation)
Blank #3: 1 (see explanation)
Explanation
Both the ammonium ion and the sulfate ion contain more than one atom in each ion. The two species are thus polyatomic. The chloride ion , for example, is monoatomic.
Superscripts above formulae of the ions indicate their charge. Each ammonium ion carries a positive one (+1) charge. Each sulfate ion carries a charge of negative two (-2).
Ammonium sulfate is an ionic compound. A sample of this compound contain myriads of ammonium ions and sulfate ions. The ions are packed in three-dimensional lattices. Thus unlike water, ammonium sulfate does not exist as molecules in nature.
Assuming that the second and third blanks refers to a formula unit, rather than a molecule, of ammonium sulfate. The empirical formula of ammonium sulfate gives the minimum whole-number ratio between the two ions in a sample.
Charges shall balance between the two ions. Ammonium ions are of charge +1. Sulfate ions are of charge -2. The sample shall thus contain two ammonium ions for every one sulfate ion.
The empirical formula of ammonium sulfate is therefore .
There are thus two ammonium ions and one sulfate ion in each formula unit of ammonium sulfate.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, a molecule of the ammonium sulfate consists of one NH₄⁺ ions and one SO₄²⁻ ions.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond. The compound of ammonium sulfate consists of two ions. NH₄⁺ and SO₄²⁻ both of which are polyatomic ions. A molecule of the ammonium sulfate consists of one NH₄⁺ ions and one SO₄²⁻ ions.
Therefore, a molecule of the ammonium sulfate consists of one NH₄⁺ ions and one SO₄²⁻ ions.
