Answer: The structure for the boron nitride molecule will be linear.

Explanation: When boron and nitrogen combine together to form a compound, the boron element will loose 3 electrons which will be easily accepted by the nitrogen element.

Boron : Atomic number is 5

Electronic configuration: 1s^22s^22p^1

To attain stable configuration, boron will loose 3 electrons easily.

Nitrogen : Atomic number is 7

Electronic configuration: is^22s^22p^3

To attain stable configuration. nitrogen will gain 3 electrons easily.

Hence, to form a molecule with these two elements, there will be 3 bonds present in between them and 1 pair of lone pair will be left on the nitrogen atom.

Structure of boron nitride ( which is linear) is attached in the image below.

Cuál es la importancia de una fórmula química y explique las clases de fórmulas con sus ejemplos respectivos.
Ksenya-84 [330]

Answer and Explanation:

Las fórmulas químicas sirven para conocer qué elementos químicos y en qué cantidad están presentes en un compuesto químico. Por ejemplo: la fórmula química del dióxido de carbono es CO₂. Esta fórmula nos indica que la molécula de dióxido de carbono está formada por 1 átomo del elemento químico carbono y 2 átomos del elemento oxígeno.

Los diferentes tipos de fórmulas químicas son: fórmula empírica, fórmula molecular, fórmula semi-desarrollada y fórmula desarrollada. Tomando como ejemplo al compuesto <em>butano</em>:

- Fórmula empírica: C₂H₅ (indica que hay 2 átomos de C por cada 5 átomos de H; es una fórmula mínima)

- Fórmula molecular: C₄H₁₀ (indica que en realidad cada molécula de butano tiene 4 átomos de C y 10 átomos de H).

- Fórmula semi-desarrollada: CH₃CH₂CH₂CH₃ (indica el órden en que se unen los átomos en la molécula).

-Fórmula desarrollada: ver dibujo adjunto (indica cómo están unidos los átomos dentro de la molécula. Ahora vemos los enlaces entre los átomos y que los 2 átomos de C de los extremos están unidos a 3 átomos de H y a otro C, y los dos átomos de C del medio están unidos cada uno a 2 C y 2 H).

How many moles of water would be produced from 3 moles of oxygen in the following reaction? Don’t forget to include units in you
wariber [46]

Answer:

6moles of water

Explanation:

Given parameters:

Number of moles of oxygen  = 3moles

  Reaction equation:

      2H₂   +   O₂   →   2H₂O

Unknown:

Number of moles of water formed  = ?

Solution:

To solve this problem;

      compare the number of moles in the reaction.

        1 mole of oxygen gas will produce 2 mole of water

        3 moles of oxygen gas will produce 3 x 2  = 6moles of water.

The skeletal structure in line‑angle (line‑bond) mode of 2‑isopropyltoluene is shown. Identify the number of hydrogen atoms boun
Shalnov [3]

Answer:

Fourteen hydrogen atoms are bounded in total to the carbon atoms in the structure

Explanation:

The boxes that show "one" indicate that there is only one hydrogen atom bonded to that particular carbon atom while those that show "zero" shows there are no hydrogen atoms bonded to that particular carbon atom. Those that show "three" indicate that there are three hydrogen atoms bonded to that particular carbon.

There are 10 carbon atoms in the structure.

NOTE that each of these carbon atoms must be surrounded with four bonds; which was how the number of hydrogen atoms (numbers in the boxes) weree determined.
