Determina la molaridad de una solución de H2S, si se colocaron 37 ml del ácido en 890 ml de solución. La densidad del H2S es de 1.36 g/ml
Por definición de molaridad y densidad, la molaridad de la solución es 1.66 [tex]\frac{moles}{litros}[/tex].
La concentración molar o molaridad es una medida de la concentración de un soluto en una disolución que indica el número de moles de soluto que están disueltos en un determinado volumen.
La molaridad de una solución se calcula dividiendo los moles del soluto por el volumen de la solución:
[tex]Molaridad=\frac{numero de moles de soluto}{volumen}[/tex]
La Molaridad se expresa en las unidades [tex]\frac{moles}{litros}[/tex].
Por otro lado, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia.
Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:
[tex]densidad=\frac{masa}{volumen}[/tex]
En este caso, siendo H₂S el soluto, se colocaron 37 ml del ácido, siendo su densidad 1.36 [tex]\frac{g}{mL}[/tex]. Reemplazando en la definición de densidad se obtiene:
[tex]1.36\frac{g}{mL}=\frac{masa}{37 mL}[/tex]
masa= 1.36 [tex]\frac{g}{mL}[/tex]× 37 mL
masa= 50.32 g
Siendo 34 g/mol la masa molar de H₂S, es decir la cantidad de masa que una sustancia contiene en un mol, la cantidad de moles de H₂S puede ser calculada como:
[tex]numero de moles de H_{2}S= 50.32 grams\frac{1 mole}{34 grams}[/tex]
número de moles de H₂S= 1.48 moles
Siendo 890 mL=0.890 L el volumen de la solución, entonces la molaridad puede ser calculada como:
[tex]Molaridad=\frac{1.48 moles}{0.890 L}[/tex]
Molaridad= 1.66 [tex]\frac{moles}{litros}[/tex]
Finalmente, la molaridad de la solución es 1.66 [tex]\frac{moles}{litros}[/tex].

Answer:
Look at the screenshot below.
Those are your answers!
Good Luck.
Explanation:
The number of valence electrons for neutral atoms is the same as the number of the atom's main group.A periodic table element's column can be used to determine its main group number.For instance, carbon, which belongs to group 4, has four valence electrons.
Use the periodic table to identify the number of valence electrons available for bonding for each of the following elements?
This rule states that each group of elements has one valence electron, two valence electrons in group 2, three valence electrons in group 13, four valence electrons in group 14, and so on. C : Six electrons make up the atom of carbon: four valence (outermost shell) electrons in the 2s and 2p orbitals, and two inner shell (core) electrons in the 1s orbital. H : As the initial element, hydrogen has an electron configuration of 1s1.Its valence shell only contains one electron.The outermost electrons or those with the highest energy level are called valence electrons. N : The periodic table's Group 15 is headed by nitrogen, which has either 3 or 5 valence electrons. O : On the periodic table, column 6 contains oxygen (symbol O).Its valence electrons number six.To obtain an octet, two bonds must be created. Ci : If chlorine removes one of its seven valence electrons, it will have eight (an octet).When chlorine gains one electron, its electron configuration resembles that of argon.If chlorine had given up all seven of its valence electrons and sodium had taken them, the octet rule would have been met.To learn more about periodic table refer

The predicted yield for a reaction was 10g of product. If the percentage yield for this reaction was 50%, how much product was formed?
The quantity of the product that was formed was 5g
From the question,
We are to determine the quantity of product formed. That is, the actual yield.
Using the formula
[tex]Percentage \ yield =\frac{Actual \ yield}{Theoretical\ yield} \times 100\%[/tex]
From the given information
Theoretical yield = 10g
Percentage yield = 50%
Putting the parameters into the formula, we get
[tex]50\% = \frac{Actual\ yield}{10} \times 100\%[/tex]
Then,
[tex]50\% = Actual\ yield \times 10\%[/tex]
∴ Actual yield = [tex]\frac{50\%}{10\%}[/tex]
Actual yield = 5g
Hence, the quantity of the product that was formed was 5g

For SCl4, the electron domain geometry is _______(i)________ and the molecular geometry is ______(ii)________.
The electron domain geometry is trigonal bipyramidal while the molecular geometry of the compound is seesaw.
The shapes of molecules is determined by the number of electron pairs on the valence shell of the central atom in the molecule. These electron domains include lone pairs and bond pairs.
The lone pairs only contribute towards the electron domain geometry and not the molecular geometry. SCl4 has five electron domains hence its electron domain geometry is trigonal bipyramidal. The molecular geometry of the compound is seesaw.

What is required for two atoms to share electrons equally in a chemical bend?
Answer: Nonpolar Covalent Bond
Explanation: A Nonpolar Covalent Bond is created when atoms share their electrons equally. This usually occurs when two atoms have similar or the same electron affinity. The closer the values of their electron affinity, the stronger the attraction. This occurs in gas molecules; also known as diatomic elements.

Explain how magnesium is produced at the negative electrode in experiment 1.
The liquified (/molten) MgCl₂ dissociates into Mg²⁺ and Cl⁻ ions;
The Cl⁻ ions are drawn to the positive electrode (which has a deficit of electrons) where they deposit electrons since they are negatively charged;
This yields Cl atoms (these will form Cl₂ gas by covalent bonding and bubbles will be seen as this gas rises out of the liquid and it will enter the air);
These electrons will flow from the positive electrode to the negative electrode;
The Mg²⁺ ions, conversely, will be drawn to the negative electrode or cathode (which has a surplus of electrons partly from those the Cl⁻ ions lose) where they pick up electrons since they have a positive charge;
This yields pure magnesium.
The magnesium has been produced with the application of electric current for the production of ions that accumulate at the electrodes.
The setup has been for the electrochemical process. The sample in the molten state has been applied with the electric current. The current results in the dissociation of the sample into ionic constituents.
The opposite charge attracts negative charge. Thus, the negative ion moves towards the positive electrode, and negative ion move towards the positive electrode. The accumulation of ions has been obtained from the electrodes.
The magnesium chloride under the influence of electric field has been converted into the positive Mg ions and negative Cl ions. The positive Mg ion will move towards the negative electrode, and thus Mg has been produced.

70 : 30. (mass ratio)
x:y = 70/56 : 30/16. (mole ratio)
1.25 : 1.875

Analysis of a molecule of DNA showed that cytosine accounted for 42 per cent of the
content of the nitrogenous bases. Calculate the percentage of bases in the molecule
which would be thymine. Show your working.
8%
Explanation:
In a DNA molecule the no. of Adenine bases equal to that of Thymine bases
The no. of Cytosine bases equal to that of Guamine bases.
If we take no. of Thymine bases as x and no. of Cytosine bases as y,
Adenine + Thymine + Cytosine + Guamine = 100
x + x + y+y = 100
2( x+y) = 100
x+y = 50
y=42
therefore x= 50-42 = 8%
