Una muestra contiene 160 g de bromo y 2 g de hidrógeno. Otra muestra de bromuro de un metal contiene 4 g de bromuro y 1 g de metal. Halla el peso equivalente del metal.

Answers

Answer 1

Answer:

Answer:

$x = 40\,g$

Explanation:

El peso equivalente del metal se calcula por regla de tres simple:

$x = \left((160\,g\,Br)/(4\,g\,Br)\right)\cdot (1\,g)$

$x = 40\,g$

Answer 2

Answer:

Answer:

El peso equivalente del metal es 1/20 g

Explanation:

Una muestra contiene 160 g de bromo y 2 g de hidrógeno. Otra muestra de bromuro metálico contiene 4 g de bromuro y 1 g de metal. Encuentra el peso equivalente del metal

Aquí tenemos la primera muestra que tiene la relación de bromo a hidrógeno de 160 g de bromo a 2 g de hidrógeno.

Eso es 160 g de bromo está presente con 2 g de hidrógeno

Dividiendo la combinación anterior por 160 para encontrar la cantidad de hidrógeno que se combina con 1 g de bromo, tenemos

(160 g) / 160 de bromo está presente con (2 g) / 160 de hidrógeno

1 g de bromo está presente con 1/80 g de hidrógeno

Por lo tanto, 4 g de bromo están presentes con 4/80 g de hidrógeno o tenemos;

4 g de bromo están presentes con 1/20 g de hidrógeno

Por lo tanto, el peso equivalente del metal = 1/20 g.

Research into nuclear fusion will likely require a large investment of time and money before it might be used as an energy source. Which statement best describes the benefits that would make the investment worthwhile? Fusion requires a large amount of energy and occurs in stars. Fusion produces large amounts of energy, and the fuel is found on Earth. Fusion produces no radioactive waste, and the fuel is plentiful. Fusion requires little energy to begin and would continue through a chain reaction.

Which statement correctly describes diamond and graphite, which are different forms of solid carbon?(1) They differ in their molecular structure, only.
(2) They differ in their properties, only.
(3) They differ in their molecular structure and properties.
(4) They do not differ in their molecular structure or properties.

Answers

Answer: Option (3) is the correct answer.

Explanation:

When an element exists in two or more different physical forms then they are known as allotropes.

For example, diamond and graphite are both allotropes of carbon.

In graphite, carbon atoms are joined together in sheets of six sided lattice. Whereas in diamond, carbon atoms are joined together in four cornered lattice.

Therefore, as these allotropes are made up of same element so they have similar chemical properties but different physical properties like melting point, boiling point etc.

Also, both of them have different molecular structure.

Thus, we can conclude that the statement the differ in their molecular structure and properties correctly describes diamond and graphite.

They differ in their molecular structures and properties.

Which of the following is NOT soluble in water? A) NaCl
B) KBr
C) CH3CH2OH
D) HCl
E) C6H6

How is this determined?

Answers

The correct answer is E. C6H6 is not soluble in water. This is determined by the polarities of these substances. Benzene is a non-polar substance because it has equal number of electrons sharing a bond thus it does not dissolve in water which is a polar substance.

all hydroxides are insoluble with the exception of those formed with alkali metal ions and barium.
Hence, CH3CH2OH is insoluble

Using the periodic table, determine which material is most likely to be a good insulator. magnesium silver aluminum sulfur

Answers

The correct answer is this one: "Magnesium." Using the periodic table, the material that is most likely to be a good insulator is the magnesium. Magnesium is a chemical element with symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column of the periodic.

Using the periodic table, determine which material is most likely to be a good insulator.

Which two physical properties allow a mixture to be separated by chromatography?(1) hardness and boiling point
(2) density and specific heat capacity
(3) malleability and thermal conductivity
(4) solubility and molecular polarity

Answers

Answer:

The correct option is: (4) solubility and molecular polarity

Explanation:

Chromatography is an analytical technique which is used for the separation of various components in a given mixture.

In this process, the mixture to be separated is first dissolved in the mobile phase, which carries it through the stationary phase, thus leading to separation of the various components.

This differential separation is the result of the differential migration which is based upon the solubility and polarity of the individual components of of the given mixture.
