Answer:

0.98 M

Explanation:

Given data:

Mass of sugar = 20 g

Mass of water = 59 g

Concentration of solution = ?

Solution:

1 g = 0.01 L

59 g× 0.01 L/1 g

0.059 L

Concentration formula:

C = m/v

m = moles of solute

v = volume of solution

Number of moles of sugar:

Number of moles = mass/molar mass

Number of moles = 20 g/ 342.3 g/mol

Number of moles = 0.058 mol

Now we will calculate the concentration:

C = 0.058 mol/0.059 L

C = 0.98 mol/L

C = 0.98 M

Answer:

0.085 moles of  N₂O₅ are needed

Explanation:

Given data:

Mass of NO₂ produces = 7.90 g

Moles of N₂O₅ needed = ?

Solution:

2N₂O₅       →     4NO₂  + O₂

Number of moles of NO₂ produced :

Number of moles = mass/ molar mass

Number of moles = 7.90 g/ 46 g/mol

Number of moles = 0.17 mol

now we will compare the moles of NO₂   with N₂O₅.

                NO₂          :       N₂O₅

                  4            :          2

                0.17          :         2/4×0.17 = 0.085 mol

Thus, 0.085 moles of  N₂O₅ are needed.

The reaction is missing, so i have attached it.

Answer:

C. An intramolecular aldol condensation

Explanation:

From the attached image showing the reaction, we can see that the left hand side of the reaction has 2 carbonyl groups which are the double bonds attached to the oxygen atoms.

Now, on the right hand side, we can see that a six member ring has been formed.

This 6 member ring is produced because one of the carbonyls on the left hand side was deprotonated at the alpha position thereby serving as a nucleophile, which then attacks the carbon in the other carbonyl.

This process is possible because it underwent the processes of deprotonation, intramolecular aldol addition, proton transfer and elimination to yield the right hand side product which is ɑ,β-unsaturated carbonyl compound.

Thus, the correct answer is option C

Answer:

Peer-reviewed Journal Article

Explanation:

1.Dictionary

2.Encyclopidia

3.Internet Search Engine

4.Peer-reviewed Journal Article

The correct answer as to which would be most useful in trying to obtain procedural information to replicate an experiment previously published would be a peer-reviewed journal article.

A peer-reviewed journal article is a journal article written by an expert or experts on a particular topic and has undergone thorough reviews by experts in the same field and certified to be of good-enough standards to be published.

Such an article would contain all the necessary information relating to the experiment leading to the article. Hence, in order to obtain procedural information to replicate an experiment that has been previously published, a peer-reviewed journal published on the same topic would do be the right place to seek.

Answer:

CaSO₃·2H₂O

Explanation:

Empirically => CaSO₃·nH₂O

%H₂O = n(H₂O)/f.wt. x 100%

23.1% = n(H₂O)100/Ca + S +3O + nH₂O

23.1 = n(18)·100/[40 + 32 + 3(16) + n(18)]

1800n = 23.1[40 + 32 + 3(16) + n(18)]

1800n = 924 + 739.2 + 1108.8 + 415.8n

1800n - 415.8n = 924 + 739.2 + 1108.8

1385n = 2772

n = 2772/1385 = 2

∴ numerical formula => CaSO₃·2H₂O

Answer:

D) will not form any stereoisomers since the product is a saturated hydrocarbon.

Explanation:

Stereoisomerism, or spatial isomerism,refers to a type of isomerism in which  two or more molecules have the same molecular formula and atom to atom connectivity but different three-dimensional orientations of those atoms in space.

Stereoisomerism occurs in alkenes because free rotation about the C=C bond is hindered. Thus, the molecule is "locked" in a particular orientation. In a saturated alkane, there is unrestricted free rotation about the C-C bond hence straight chain alkanes do not have steroisomers.

The product formed is 3,4-dimethyl hexane which is a straight chain saturated alkane. This compound does not exhibit stereoisomerism.

Answer:

Volume of ammonia produced = 398.7 dm³

Explanation:

Given data:

Volume of N₂ = 200 dm³

Pressure and temperature = standard

Volume of ammonia produced = ?

Solution:

Chemical equation:

N₂ + 3H₂     →      2NH₃

Number of moles of N₂:

PV = nRT

1 atm× 200 L = n× 0.0821 atm.L/mol.K × 273 K

n = 200 atm.L /22.41 atm.L/mol

n = 8.9 mol

Now we will compare the moles of ammonia and nitrogen.

               N₂          :         NH₃

                1            :           2

              8.9          :        2/1×8.9 = 17.8 mol

Volume of ammonia:

1 mole of any gas occupy 22.4 dm³ volume

17.8 mol ×22.4 dm³/1 mol = 398.7 dm³

Answer:

Explanation:

I dont now if this is wht you were looking for so srry

The pressure of the gas at which the final volume of the gas has been 3 L has been 0.833 atm.

The gas has been assumed to be at constant temperature. The change in the pressure and volume of gas at constant temperature can be given by:

Initial pressure × Initial volume = Final pressure × Final volume

The initial pressure of gas has been 0.5 atm, and the initial volume has been 5L. The increased volume or final volume of the system has been 3 L.

The final pressure of the gas has been given by:

0.5 atm × 5 L = 3 L × Final pressure

Final pressure = 0.833 atm.

The pressure of the gas at which the final volume of the gas has been 3 L has been 0.833 atm.

Answer:

Mass =  11.16 g

Explanation:

Given data:

Mass of hydrogen = 8 g

Mass of oxygen = 10 g

Mass of water produced = ?

Solution:

Chemical equation:

2H₂ + O₂         →      2H₂O

Number of moles of hydrogen:

Number of moles = mass / molar mass

Number of moles = 8 g/ 2 g/mol

Number of moles = 4 mol

Number of moles of oxygen:

Number of moles = mass / molar mass

Number of moles = 10 g/ 32 g/mol

Number of moles = 0.31 mol

now we will compare the moles of hydrogen and oxygen with water.

                   O₂          :           H₂O

                    1            :             2

                  0.31         :            2/1×0.31 = 0.62

                  H₂           :            H₂O

                    2            :              2

                     4            :              4

Number of moles of water formed by oxygen are less this it will act as limiting reactant.

Mass of water:

Mass = number of moles × molar mass

Mass = 0.62 mol × 18 g/mol

Mass =  11.16 g

Answer:

H2CO

Explanation:

Answer:

carbon dioxide and water.

Explanation:

Chemical equation:

2C₂H₆ + 7O₂      →    4CO₂ + 6H₂O

Reactants are present on the left side of chemical equation while products are present on the right side of chemical equation. In given chemical equation ethane and oxygen are reactant while carbon dioxide and water are product.

The given reaction is combustion reaction. Ethane is burnt in the presence of oxygen and produces carbon dioxide and water.

The reaction also follow the law of conservation of mass.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
