Answer:

Los elementos de la tabla periódica se distribuyen sobre la base de similitudes.

Explicación:

Los diferentes tipos de elementos se distribuyen en 8 grupos de tabla periódica en función de sus propiedades. Los elementos que tienen propiedades similares se colocan en el mismo grupo. Por ejemplo, el primer grupo de la tabla periódica son los metales alcalinos. Todos los metales alcalinos tienen algunas propiedades similares, es decir, un electrón en su capa más externa, alta reactividad y forma metálica, mientras que, por otro lado, los ocho elementos del grupo son gases nobles que tienen una capa más externa completa y no tienen reactividad.

A sample of helium (He) effuses 2.0 times faster than another gas. What is the molar mass of the other gas?
Mariana [72]

Answer:

The correct answer is 16 gram per mole.

Explanation:

Let A be the gas helium, and B be the unknown gas. It is clearly mentioned in the question that the effusion rate of helium gas is two times more than that of gas B. The molar mass of helium is 4.0 gram per mole. To solve the problem, Grahm's law is used, that is,  

Rate of effusion A/rate of effusion B = √ (Molar mass B/Molar mass of A

2.0 = √Molar mass of B/4.0 gram per mole.  

Now squaring both the sides we get,  

4.0 = Molar mass of B / 4.0

The molar mass of B = 16 gram per mole.

The substance whose lewis structure shows three covalent bonds is
Gnoma [55]

The substance whose Lewis structure shows three covalent bonds is Nitrogen gas molecule.

<h3>What is Lewis structure?</h3>

Lewis structure is a dot structure which gives idea about the number of valence electrons that are involved in the bonding within the molecule.

Lewis dot structure of nitrogen gas will be expressed as in the attached image, where between two nitrogen atoms triple bond is present. That triple bond is formed by the sharing of electrons and known as covalent bonds.

Hence in nitrogen gas molecule three covalent bonds is present.
