How many grams of KCl are produced if 25g of KCIO3 decompose?
2KCIO3
2KCI
+
302
Answers
Answer:
15 g
Explanation:
The reaction that takes place is:
2KCIO₃ → 2KCI + 3O₂First we convert 25 g of KCIO₃ to moles, using its molar mass:
25 g ÷ 122.55 g/mol = 0.204 mol KCIO₃Then we convert KCIO₃ moles to KCl moles, using the stoichiometric coefficients:
0.204 mol KCIO₃ * [tex]\frac{2molKCl}{2molKClO_3}[/tex] = 0.204 mol KClFinally we convert KCl moles to grams, using the molar mass of KCl:
0.204 mol KCl * 74.55 g/mol = 15.2 g) An organic chemistry lab book gives the following solubility data for oxalic acid 9.5g/100ml water 23.7g/100ml ethanol 16.9g/100ml ether (a) A 14CL student has 40 g of oxalic acid in 1000ml of water and wishes to extracted into an organic solvent for further experiments. Which solvent should the student use for the extraction
Answers
Answer:
Ethanol
Explanation:
Solvent extraction is the process in which a compound transfers from one solvent to another owing to the difference in solubility or distribution coefficient between these two solvents(Science Direct).
We have to remember that oxalic acid will be extracted better into a solvent in which it is more soluble. From the data given; oxalic acid is more soluble in ethanol than in ether.
This simply means that ethanol is a better solvent for extracting oxalic acid from water when compared to ether.

Use the Henderson-Hasselbalch equation, eq. (3), to calculate the pH expected for a buffer solution prepared from this acid and its conjugate base, assuming: the mass of the weak acid is 0.2 g and the mass of the conjugate base is 0.2 g will be added to 25 mL of water. Also assume the molar mass of the weak acid is 234 and its conjugate base is the sodium salt.
Answers
Answer:
[tex]pH=4.56[/tex]
Explanation:
Hello there!
In this case, given the Henderson-Hasselbach equation, it is possible for us to compute the pH by firstly computing the concentration of the acid and the conjugate base; for this purpose we assume that the volume of the total solution is 0.025 L and the molar mass of the sodium base is 234 - 1 + 23 = 256 g/mol as one H is replaced by the Na:
[tex]n_{acid}=\frac{0.2g}{234g/mol}=0.000855mol\\\\n_{base}= \frac{0.2g}{256g/mol}=0.000781mol[/tex]
And the concentrations are:
[tex][acid]=0.000855mol/0.025L=0.0342M[/tex]
[tex][base]=0.000781mol/0.025L=0.0312M[/tex]
Then, considering that the Ka of this acid is 2.5x10⁻⁵, we obtain for the pH:
[tex]pH=-log(2.5x10^{-5})+log(\frac{0.0312M}{0.0342M} )\\\\pH=4.60-0.04\\\\pH=4.56[/tex]

Explanation:
Rotation about C-C single bonds allows a compound to adopt a variety of _____________. conformations configurations formations isomers projections are often used to draw the various conformations of a compound. conformations are lower in energy, while conformations are higher in energy. The difference in energy between staggered and eclipsed conformations of ethane is referred to as strain. strain occurs in cycloalkanes when bond angles deviate from the preferred °. The conformation of cyclohexane has no torsional strain and very little angle strain. The term "ring flip" is used to describe the conversion of one conformation into the other. When a ring has one substituent the equilibrium will favor the chair conformation with the substituent in the position.
Answers
Answer:
Conformation
Explanation:
Conformation refers to "any of the spatial arrangements which the atoms in a molecule may adopt and freely convert between, especially by rotation about individual single bonds"(Oxford dictionary).
Carbon-Carbon single bonds are known to undergo rotations about its axis. These rotations leads to various conformations. The energy difference between conformations may be low or high depending on the structure of the molecule. The difference in energy between conformations determines a molecules's preferred conformation.
A sample of gas in a cylinder as in the example in Part A has an initial volume of 56.0 L , and you have determined that it contains 1.80 moles of gas. The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 14.0 L . How many moles of gas (n2) remain in the cylinder
Answers
Answer: The moles of gas that remain in the cylinder are 0.45
Explanation:
According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,
[tex]V\propto n[/tex]
or [tex]\frac{V_1}{n_1}=\frac{V_2}{n_2}[/tex]
where,
[tex]V_1[/tex] = initial volume of gas = 56.0 L
[tex]V_2[/tex] = final volume of gas = 14.0 L
[tex]n_1[/tex] = initial moles of gas = 1.80
[tex]n_2[/tex] = final moles of gas = ?
Putting the values , we get:
[tex]\frac{56.0}{1.80}=\frac{14.0}{n_2}[/tex]
[tex]n_2=0.45[/tex]
The moles of gas that remain in the cylinder are 0.45

2) if 6.022*10²³ molecules are in 1 mol, then 4.11*10²³ molecules are in
x=6.022*10²³ / 4.11*10²³=6.022/4.11≈1.47 moles.

Explanation:
According to the attached mechanism, we have a Sn1 reaction. The diethyl ether formed is because we have a nucleophilic site and an electrophilic site. Now which one is?.
If you see the mechanism below, you can see that the -OH has a lone pair of electrons. This lone pair attacks the carbon that is attached to the bromine. This attack, makes the ethyl alcohol the nucleophyle, and the ethyl bromide, which have the leaving group (The bromine) the electrophyle.

What is Charge ?
Charge is a basic property of matter that is associated with the presence or absence of electrons. Objects can have positive or negative charge, or they can be neutral, which means they have an equal number of positive and negative charges. In physics, charge is one of the fundamental concepts used to explain the behavior of matter and energy in the universe. The interaction between charges is described by Coulomb's law, which states that the force between two charges is proportional to the product of their charges and inversely proportional to the square of the distance between them.

Perform each conversion
5.88 dL to liters
Answers
Answer:
5.88 dL = 0.588 litre
Explanation:
We need to find a conversion from 5.88 dL to liters.
We know that the conversion is as follows :
1 deciliter = 0.1 litre
To find 5.88 dL to liters, we use the unitary method. So,
5.88 dL= (0.1×5.88) litre
5.88 dL = 0.588 litre
So, there are 0.588 liters in 5.88 dL.
