An example of a solid solution is copper true or false

Hunter-Best [27]

Answer:

28.23 g NH₃

Explanation:

The balanced chemical equation is:

N₂(g) + 3 H₂(g) → 2 NH₃(g)

Thus, 1 mol of N₂ reacts with 2 moles of H₂ to produce 2 moles of NH₃. We convert the moles to mass (in grams) by using the molecular weight (MW) of each compound:

MW(N₂) = 2 x 14 g/mol = 28 g/mol

mass N₂= 1 mol x 28 g/mol = 28 g

MW(H₂) = 2 x 1 g/mol = 2 g/mol

mass H₂ = 3 mol x 2 g/mol = 6 g

MW(NH₃) = 14 g/mol + (3 x 1 g/mol) = 17 g/mol

mass NH₃= 2 moles x 17 g/mol = 34 g

Now, we have to figure out which is the limiting reactant. For this, we know that the stoichiometric ratio is 28 g N₂/6 g H₂. If we have 36.85 g of H₂, we need the following mass of N₂:

36.85 g H₂ x 28 g N₂/6 g H₂ = 171.97 g N₂

We have 23.15 g N₂ and we need 171.97 g. So, we have lesser N₂ than we need. Thus, the limiting reactant is N₂.

Now, we calculate the product (NH₃) by using the stoichiometric ratio 34 g NH₃/28 g N₂, with the mass of N₂ we have:

23.25 g N₂ x 34 g NH₃/28 g N₂ = 28.23 g NH₃

Therefore, the maximum amount of NH₃ that can be produced is 28.23 grams.

In salt, what is the nature of the bond between sodium and chlorine? in salt, what is the nature of the bond between sodium and

kifflom [539]

A chemical bond that involves the transfer of electrons from a metal to a nonmetal and thus forms ions and the atoms in the molecule are attracted towards each other through electrostatic force of attraction are said be ionic bond. In short, the bond formed between the two oppositely charged ions.

In salt, the compound formed between sodium and chlorine is sodium chloride having molecular formula $NaCl$ where sodium is a metal and chlorine is the non-metal. The formation of the compound takes place by transfer of an electron from sodium thus forming a cation of formula $Na^{+}$ to chlorine which gains electron and thus results in an anion formation having formula $Cl^{-}$ . The force of attraction between these oppositely charged ions that helds them together and results in formation of $NaCl$ compound is electrostatic force of attraction.

Hence in salt, the nature of bond between sodium and chlorine is ionic.

Predict the sign of ΔSsys for each process: (b) A solid explosive converts to a gas.

Goryan [66]

The sign of ΔSsys for a solid explosive converts to a gas is positive.

The term used for the measurement of randomness and disorderliness in a system is known as Entropy (S). ΔS calculates the change in entropy and it is positive when entropy increase and negative when entropy decreases.

Entropy increases when heat is added to the system. Addition of heat increases the randomness of the molecules and hence the entropy increases.

When a solid explosive converts to a gas the randomness increases. Explosive causes heat and the solid is converted into gas. The randomness of molecules is maximum in gases thus the entropy increases. The sign of ΔS is positive for this process.

Please help me name this alkane

Mrac [35]

I assume you are already familiar with the IUPAC rules. I will be referring to the rule number where applicable. If you do not have a copy of the IUPAC rules, please let me know by a comment or PM.

Alkane (A)
The first one is tricky, because the longest straight chain is not as drawn, but along a "branch". See first image.
Since there are 10 carbon atoms in the longest chain, the parent chain will be named decane.
The first substituent occurs in C3, that explains why the parent chain is named from right to left.
Now the substituents:
C3 : Cl and CH3, so 3-chloro 3-methyl
C6 : The Y-shape is named isopropyl, so 6-isopropyl
C7 : Substituent is a straight chain with 2 carbon atoms, so 7-ethyl
The complete name is therefore
3-chloro-7-ethyl-3-methyl-6-isopropyl-decane
Note that order is according to alphabetic order of the substituent name without the prefixes (explains why isopropyl comes after methyl)

Alkane (B)
Again, first step is to look for the longest chain, which is 11 (undecane), as numbered in image 2.
Numbering starts from the 2,2-dichloro end because it gives the lowest number for the locant.
C2 2,2-dichloro (2 branches, each is Cl)
C4 4-methyl (1 carbon atom)C5 5-ethyl (2 carbon atoms)
C8 8-ethyl
C9 9-methyl
So the complete name is
2-2-dichloro-5,8-diethyl-4,9-dimethyl-undecane

Alkane (C)
Here there are 9 carbon atoms (nonane) in the longest chain.
The locants of substituents are identical from either end. Here I choose the one with the smaller number of the first substitutent 2-methyl instead of 2,2-dimethyl, resulting the numbering starting from the right. I hope I am right here.
C2 1-methyl
C3 1-methyl
C4 1-methyl
C5 1-methyl
C6 6-fluro-6-iodo
C7 1-methyl
C8 8,8-dimethyl
So the complete name becomes
6-fluoro-6-iodo-2,3,4,5,7,8,8-heptamethyl nonane

To @study77 and anyone reading this answer:
Please check and understand everything I did in case I slipped somewhere. Any suggestion for improvement or corrections will be most appreciated.
