EN LA MINA DE CHUQUICATAMA SE EXPLOTA DIFERENTES METALES COMO SER EL COBRE , AL ESTAR EN CONTACTO CON EL AIRE DICHO METAL SE LLEGA A OXIDAR FORMANDO DOS CLASES DE OXIDO¿CUALES SON ESTOS DOS OXIDOS?

Answers

Answer:

Los dos óxidos que forma el cobre son óxido de cobre (I) y óxido de cobre (II) (Cu₂O y CuO, respectivamente).

   

Explanation:

El cobre posee dos estados de oxidación más comunes, los cuales son +1 y +2.

En contacto con aire el cobre se puede oxidar para dar lugar al óxido cuproso u óxido de cobre (I):

4Cu + O₂ → 2Cu₂O

Dicha oxidación también puede dar lugar a la formación del óxido cúprico u óxido de cobre (II):

2Cu + O₂ → 2CuO

La formación del óxido cúprico se favorece a temperaturas mayores a la del ambiente (por encima de los 300 °C).

Por lo tanto, los dos óxidos que forma el cobre son óxido de cobre (I) y óxido de cobre (II) (Cu₂O y CuO, respectivamente).

What is the molarity of the solution formed by dissolving 80. G of NAOH(s) into water to give a total volume of 4.00 l

Answers

Answer:

0.5 M

Explanation:

From the question given above, the following data were obtained:

Mass of NaOH = 80 g

Volume of solution = 4 L

Molarity =?

Next, we shall determine the number of mole in 80 g of NaOH. This can be obtained as follow:

Mass of NaOH = 80 g

Molar mass of NaOH = 23 + 16 + 1

= 40 g/mol

Mole of NaOH =?

Mole = mass / molar mass

Mole of NaOH = 80 / 40

Mole of NaOH = 2 moles

Finally, we shall determine the molarity of the solution. This can be obtained as follow:

Mole of NaOH = 2 moles

Volume of solution = 4 L

Molarity =?

Molarity = mole / Volume

Molarity = 2/4

Molarity = 0.5 M

Therefore, the molarity of the solution is 0.5 M.

What mass of barium sulfate (233 g/mol) is produced when 125 mL of a 0.150 M solution of barium chloride is mixed with 125 mL of a 0.150 M solution of iron(III) sulfate

Answers

Answer:

4.37 g of barium sulphate

Explanation:

The reaction equation is;

3BaCl2(aq) + Fe2(SO4)3(aq) ---->3 BaSO4(s) + 2FeCl3(aq)

From the question, the number of moles of both barium chloride and FeSO4 = 125/1000 L × 0.150 M = 0.01875 moles

To find the limiting reactant;

3 moles of barium chloride yields 3 moles of barium sulphate

0.01875 moles of barium chloride yields 3 × 0.01875 moles/3 = 0.01875 moles of barium sulphate

1 mole of iron III sulphate yields 3 moles of barium sulphate

0.01875 molesof iron III sulphate yields 0.01875 moles ×3/1 = 0.05625 moles of barium sulphate

Hence,barium chloride is the limiting reactant

Amount of barium sulphate produced = 0.01875 moles × 233 g/mol = 4.37 g of barium sulphate

How many atoms are there in 1 g of argon?

The Avogadro constant is 6.02 × 1023 per mole.

Relative atomic mass (Ar): Ar = 40

Answers

Answer:

1.5057×10^22 atom

Explanation:

As we

1 mole of argon = 40 g of argon

i.e 40 g of argon = 1 mole of argon

1 g of argon = 1/40 mole of argon

1 mole of argon = 6.023×10^23 atom of argon

1/40 mole if argon = 1/40 ×6.023×10^23

= 1.5057×10^22

The number of atoms of Argon in 1 g would be 1.51 × 10²²

To find out the number of atoms of Argon in 1 g of Argon, the number of moles has to be calculated from which the number of atoms can be derived.

The molecular mass of Argon is 40. The number of moles of Argon is calculated as:

Number of moles of Argon = [tex]\frac{Mass of Argon in grams}{Molecular mass of Argon}[/tex]

Substituting molecular mass as 40 and mass in grams as 1. we get:

Number of moles of Argon = [tex]\frac{1}{40}[/tex] = 0.025 mol

Number of atoms in 1 mole of any substance is given by Avogadro's number as 6.022 × 10²³.

Thus, number of atoms of Argon in 0.025 moles would be

= 0.025 × 6.022 × 10²³

= 0.151 × 10²³ or 1.51 × 10²²

If a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then what happens to the temperature of the gas?

Answers

Answer: If a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then temperature of the gas increases twice.

Explanation:

Charles law states that at constant pressure, the volume of a gas is directly proportional to the temperature.

That is, [tex]V \propto T[/tex].

So, when a gas is pumped from a smaller container to a container that is twice the size shows that volume is increasing by 2 times and its pressure is kept the same.

Therefore,

[tex]2V \propto 2T[/tex]

This means that the temperature of the gas will also become twice its initial temperature.

Thus, we can conclude that if a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then temperature of the gas increases twice.

CH4 (g) + O2 (g) → CO2 (g) + H2O (g) to. If 28.6 g of CH4 is reacted with 57.6 g of O2, calculate the number of grams of CO2 produced. b. If you actually get 32.1 g of CO2, calculate the percent yield. c. Calculate the number of moles of excess reagent remaining at the end of the reaction.

Answers

Answer:

See explanation

Explanation:

First we must obtain the limiting reactant. The equation of the reaction is;

CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)

Number of moles of CH4= 28.6 g/16g/mol = 1.8 moles

Since the reaction is 1:1, 1.8 moles of CO2 was produced

Number of moles of O2 = 57.6 g/32 g/mol = 1.8 moles

2 moles of O2 produced 1 mole of CO2

1.8 moles of O2 produced 1.8 × 1/2 = 0.9 moles of CO2

Hence O2 is the limiting reactant

Mass of CO2 produced = 0.9 moles × 44 g/mol = 39.6 g

%yield = 32.1g/39.6 g × 100

%yield = 81.1%

According to the reaction equation;

2moles of O2 reacts with 1 mole of CH4

1.8 moles of O2 reacts with 1.8 × 1/2 =0.9 moles of CH4

Number of moles of CH4 left = 1.8 moles - 0.9 moles

Number of moles of CH4 left = 0.9 moles

Answer:

More

Explanation:

When a constraint is imposed on a reaction system in equilibrium, the equilibrium position will shift in such a way as to annul the constraint.

When the volume of a reaction system in equilibrium is decreased, the equilibrium position will shift in the direction having less total number of moles.

Similarly, when the volume is increased, the equilibrium position shifts to the direction having a greater total number of moles.
