Answer:

Hello. The answer is A (10)

Explanation:

If you memorize the periodic table it will be very easy to answer.

But if you don't know،

The solution is to count the electrons number

In an atom usually electrons number is equal with protons number

In this shape there are 10 electrons

So there are 10 protons in nucleus.

Un compuesto formado por carbono, hidrógeno y oxígeno tiene una masa de 4,6 g. Se hace reaccionar con 9,6 g de oxígeno dando 8,8 g de CO2 y 5,4 g de agua. Si cogemos 9,2 g de un compuesto en un volumen 5,80l en P= 780 mmHg a una temperatura de 90ºC. Calcula la fórmula empírica y molecular.

Answers

Answer:

La fórmula empírica y molecular es: C₂H₆O.

Explanation:

Para calcular la formula empírica y molecular del compuesto debemos primero plantear la reacción:  

[tex] C_{x}H_{y}O_{z} + O_{2} \rightarrow CO_{2} + H_{2}O [/tex]

Necesitamos encontrar "x", "y" y "z". Para ello, tenemos que recordar que la masa de carbono e hidrógeno producida está relacionada con la cantidad de C y H inicial (del compuesto):

Para el H:

CHO → H₂O

y          5,4g

[tex] \frac{2*1 g}{18 g} = \frac{y}{5,4 g} \rightarrow y = 0,6 g [/tex]

Para C:  

CHO → CO₂

 x         8,8g

[tex] \frac{12 g}{44 g} = \frac{x}{8,8 g} \rightarrow x = 2,4 g [/tex]

Para el O:

[tex] z = 4,6 g - 2,4 g - 0,6 g = 1,6 g [/tex]

Ahora mediante el calculo de los moles del C, H y O podemos encontrar la fórmula empírica:

Para el H:

[tex] n_{y} = \frac{m}{Pm} = \frac{0,6 g}{1 g/mol} = 0,6 moles [/tex]

Para el C:

[tex] n_{x} = \frac{m}{Pm} = \frac{2,4 g}{12 g/mol} = 0,2 moles [/tex]

Para el O:

[tex] n_{z} = \frac{m}{Pm} = \frac{1,6 g}{16 g/mol} = 0,1 moles [/tex]

[tex] C_{\frac{n_{x}}{n_{z}}}H_{\frac{n_{y}}{n_{z}}}O_{\frac{n_{z}}{n_{z}}} = C_{\frac{0,2}{0,1}}H_{\frac{0,6}{0,1}}O_{\frac{0,1}{0,1}} = C_{2}H_{6}O_{1} [/tex]

Entonces, la fórmula empírica del commpuesto formado es C₂H₆O.

Ahora para determinar la fórmula molecular podemos usar la siguiente relación:

[tex] \frac{Pm}{Pm_{e}} = n [/tex]

[tex] F_{m} = n*F_{e} [/tex]

[tex] F_{m} = \frac{Pm}{Pm_{e}}*F_{e} [/tex]    

En donde Fm (fórmula molecular) y Fe (fórmula empírica) están relacionadas por n.

El valor de Pm lo obtenemos de la ecuación del gas ideal:

[tex]PV = nRT = \frac{m}{Pm}RT[/tex]

[tex] Pm = \frac{mRT}{PV} = \frac{9,2 g*0,082 L*atm/(K*mol)*(90 + 273 K)}{1.02 atm*5,80 L} = 46,3 g/mol [/tex]

[tex] F_{m} = \frac{46,3 g/mol}{(2*12 + 6*1 + 16)g/mol}*C_{2}H_{6}O_{1} = 1.00*C_{2}H_{6}O_{1} = C_{2}H_{6}O_{1} [/tex]    

Por lo tanto, la fórmula molecular es la misma que la fórmula empírica, a saber C₂H₆O.

A 5.0 milliliter sample of a substance has a mass of 12.5 grams. What is the mass of a 100 milliliter sample of the same substance?

Answers

Answer:

It sould be 250 grams

Explanation:

It is given that, 5 millimeter sample has the mass of 12.5 grams. Then, 100 millimeter sample have a mass of  250 g.

What is mass ?

Mass of a substance is a physical quantity that describes the total amount of the substance. Mass is an extensive property since it depends on the change in amount or quantity of the substance.

The SI unit of mass is grams (g). Other units are kilograms, milligrams , pounds etc. Mass is of small substance is expressed in grams and that bigger things are usually expressed in kilograms.

Given that mass of 5 ml sample = 12.5 grams

then mass of 1 ml = 12.5/5 = 2.5 g

then mass of 100 ml = 2.5 × 100 = 250 grams.

Therefore, the mass of 100 ml of the sample is 250 g.

[ N 2 ] = 0.750 M. What is the equilibrium constant for this reaction? c= K c =

Answers

Answer:

0.324

Explanation:

The following data were obtained from the question:

Concentration of NH3, [NH3] = 0.25 M

Concentration of H2, [H2] = 0.3 M

Concentration of N2, [N2] = 0.75 M

Equilibrium constant (Kc) =.?

The balanced equation for the reaction is given below:

2NH3 <==> 3H2 + N2

The equilibrium constant, Kc for a given reaction is the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient. Thus, the equilibrium constant for the above reaction can be obtained as illustrated below:

Kc = [H2]³ [N2] / [NH3]²

Concentration of NH3, [NH3] = 0.25 M

Concentration of H2, [H2] = 0.3 M

Concentration of N2, [N2] = 0.75 M

Equilibrium constant (Kc) =.?

Kc = [H2]³ [N2] / [NH3]²

Kc = [0.3]³ × [0.75] / [0.25]²

Kc = (0.027 × 0.75) / 0.0625

Kc = 0.02025 / 0.0625

Kc = 0.324

Therefore, the equilibrium constant for the reaction is 0.324

Answers

Answer:

sulfur

Explanation:

From the given lists of elements, the one with the most electronegativity is Sulfur.

  Electronegativity is of an element is a property that combines the ability of its atom to lose and gain electrons.

It is a measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.

 

Using the Pauling's electronegative table of elements;

   Here are electronegativity values of the given elements;

selenium                 2.4

arsenic                    2.0

phosphorus            2.1

sulfur                      2.5

We see that the value of sulfur is the highest.

It is incorrect because it should have a total of eight electrons with two electrons between each H and O

Further explanation

Lewis structure shows the form of bonds that occur in the valence electrons of an element or compound

This bonding usually occurs in covalent bonds

Valence electrons are electrons used in a chemical bond

The main group elements usually have valence electron configurations in the ns and np subshells, While the transition elements in the subshells (n-1) d and ns.

Element O has 6 valence electrons

Element H has 1 valence electron

To achieve stability, the element O needs 2 more electrons which are obtained from 2 electrons from the H element, while the H element needs 1 electron to be stable

So that a covalent bond is formed

The protons and neutrons are in the nucleus of the atom, while the electrons are on the outside. How would you calculate the number of neutrons in an atom? Subtract the atomic mass and the atomic number. Add the atomic mass and the atomic number. Subtract the number of protons from the atomic number. Add the number of protons to the atomic number. ​
