How many grams are in 3.4 moles of Lead (IV) Sulfate (Pb(SO4)2)? ) Molar mass: 303.26 g/mol 131.0840​

Answers

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.

Which neutral atom is isoelectronic with N-3?

Answers

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).

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

Answers

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.

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

Answers

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

What should the IUPAC name for a binary covalent compound lack? prefixes Roman numerals an -ide ending the name of a nonmetal.

Answers

The IUPAC name for a binary covalent compound will lack roman numerals.

Binary covalent compound comprises of two elements which forms a

compound through the sharing of electrons.

The sharing of electrons is referred to as covalent bonding and naming such

compounds require prefixes such as mono-, di- , tri- etc.

The standard method of naming these compounds should be with the

prefixes and not with the roman numerals.

An example is carbon(IV)oxide which is wrong in  IUPAC naming.

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?

Answers

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.
