Is this a balanced equation? 4NH3+ 5O2 – 4NO + 5H20

Chemistry

3 0

Answer:

The reaction is not balanced.

Explanation:

The reaction expression is given as:

4NH₃ + 5O₂ → 4NO + 5H₂O

In a balanced reaction equation, the number of atoms on both sides of the expression is the same.

Now let us investigate;

Elements N H O

Reactants 4 12 10

Products 4 10 9

We see that the number of H and O on both sides of the expression is not the same. The reaction is not balanced.

Give the electron configuration of vanadium (V), atomic number 23

saveliy_v [14]

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d³ or [Ar] 4s²3d³

<h3>Further explanation</h3>

Given

Vanadium, atomic number 23

Required

The electron configuration

Solution

In an atom, there are levels of energy in the shell and subshell

This energy level is expressed in the form of electron configurations.

Charging electrons in the subshell uses the following sequence:

The electron configuration is based on the atomic number which indicates the number of electrons of the atom

Vanadium has the atomic number 23, so the number of electrons = 23

Electron configuration:

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d³

or we can write it using the noble gas notation

[Ar] 4s²3d³

How many valence electrons are in two fluorine atoms

olga nikolaevna [1]

Answer:

If both fluorine atoms are combine than each atom have 8 valance electrons and total valance electrons in both atoms are 16.

Explanation:

Fluorine is halogen atom. The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements.

There seven valance electrons in each halogen atom. They need one electron to complete the octet.

Fluorine atom combine with its another atom through covalent bond and share its one of valance electron with other atom thus both have 8 valance electrons and total valance electrons in both atoms are 16.

What best describes the heat transfer when kinetic energy is converted into potential energy?

Masteriza [31]

Answer:

neither of them, kinetic energy is energy in motion and potential is stored energy so its like saying the heat transfer stopped in a pot

i dont know if that made sense XD

How many valence electrons does the lewis structure for a chlorine atom show? the molecule structure of cl has with electrons a.

blsea [12.9K]

Seven valence electrons are present in the 'Lewis structure' for the given chlorine atom

A Chlorine atom has total 17 electrons in total. In the 'first orbit' 2 electrons, 10 electrons in the 'second orbit' and finally 7 electrons in the last orbit. As Chlorine is a Group 7 element, chlorine will have 7 'valence electrons' in its outermost orbit. While drawing the 'Lewis structure' of Chlorine we shall put seven dots that is the electrons or valance electrons around the symbol of Chlorine (CI).

<h3>What are Valence electrons ?</h3>

The electrons in an atom's outermost shell, or energy level, are called valence electrons. For instance, the valence electrons of oxygen are six, with two in the 2s subshell and four in the 2p subshell.

An atom's outer shell electrons, known as valence electrons, can take role in the creation of chemical bonds. When two atoms establish a single covalent bond, normally both atoms contribute one valence electron to create a shared pair. The ground state of an atom is its state with the least amount of energy.
