What Are The Chemical Compounds That Makeup Water? | H2+O2=H2O

Water is a straightforward and vital chemical compound composed of two hydrogen atoms (H) and one oxygen atom (O), which is usually referred to by the name H2O. The arrangement of the atoms within the water molecule provides it with distinct properties that make it necessary for life on Earth.

Chemical formulas for water are H2O meaning that every water molecule contains two hydrogen atoms and one oxygen atom. The hydrogen atoms are linked to the oxygen atom by covalent bonds. They share electrons. Oxygen atoms are more negative than hydrogen atoms. That means that it draws the electrons that share a space closer to itself, leading to a slight negative electron charge for the oxygen atom and an inversely positive charge for hydrogen atoms.

In the end, the combination of two hydrogen atoms and the oxygen atom creates a polar molecule with bent shapes that gives it distinctive characteristics like high surface tension, a large heat capacity, and the capability to dissolve many different substances.

How to Balance:

H2 + O2 – H2O

Word equation: Hydrogen gas + Oxygen gas – water

A Chemical Reaction Type: We are dealing with a combination reaction for this chemical reaction.

Balance Strategies: In this reaction, it is recommended to begin with changing the coefficient at the front of the H 2O and ensuring you’re left with an even amount of oxygen atoms. Once you have done that, you can move to the reaction side of the equation (and on the other side) and, quite easily, balance the rest of the equation.

This is a good way to ensure you know because many introductory courses employ this as an illustration. It is often used to start the stoichiometry problem as well.

When we balance chemical equations, we aim to get the exact amount of each kind of atom in both equations.

Change only these coefficients (the numbers found before the substances).

Never change the subscripts (the small numbers after elements).


Hydrogen is the most abundant element in the universe. It is present in all animal and vegetable tissue and in the oceans, ice packs, rivers, lakes, and atmosphere. It is also a vital component of carbon compounds.

It is by far the largest element present in our universe. As a result, it is a key component in many chemical reactions, including the creation of H2O and water. In this article, we’ll examine the role of hydrogen in H2O and the significance it plays in our lives.

What Is H2O?

It is the chemical formula used to describe water, which is a colorless, inert, tasteless liquid that is necessary for the existence of life on Earth.

The Importance Of Hydrogen In H2O:Denes Kozma LdL0AanxJx4 Unsplash

Hydrogen is a key element in H2O. Without it, water wouldn’t exist. Hydrogen is extremely reactive and creates covalent bonds to other elements, like oxygen and carbon dioxide, to create molecules. In H2O, two hydrogen atoms join to one oxygen atom by covalent bonds by sharing electrons, resulting in a stable atom.

The hydrogen properties in H2O play a significant role in determining the distinct features of water. For instance, the electronegativity of oxygen atoms is higher than that of hydrogen atoms, which means that the electrons of the covalent bonds are more closely to the oxygen atoms than hydrogen atoms. This creates the presence of a negative charge to the oxygen atom and the partial positive charge of hydrogen atoms, making water the polar molecule.

The water’s polarity allows it to create hydrogen bonds with other polymers, forming the appearance of a lattice, providing water with high surface tension. This is essential to water transportation within plants, allowing it to travel against gravity in narrow tubes like vessels for the xylem.

Hydrogen bonds also provide water with an extremely high capacity for heat, which means it can absorb and release huge amounts of heat energy without altering its temperature drastically. This is essential for the regulation of temperature in living organisms.

As it helps maintain body temperature and stop abrupt temperature fluctuations.

One of the primary elements that compose the water we drink is hydrogen. It is by far the largest element in the universe and plays an important part in the chemistry of life. For example, hydrogen in water creates solid bonds to oxygen, creating H2O molecules. These bonds, referred to as hydrogen bonds, are vital to the unique properties of water.

Hydrogen bonds can be described as intermolecular forces created in the case of a hydrogen atom covalently linked to an electronegative atom like nitrogen or oxygen and is attracted by another electronegative atom in the vicinity. For water, the hydrogen atoms are linked to oxygen, and the hydrogen bonds that result create the unique properties of water.

The primary characteristic of water that is affected by hydrogen bonds is the strong surface tension. The force of surface tension keeps the liquid’s surface together and withstands external forces. Hydrogen bonds between water molecules create a surface tension that permits small objects, like insects, to walk across the water’s surface but not penetrate.

Another characteristic associated with water, affected through hydrogen bonds, is the capacity to dissolve various substances. Water is often referred to for its role as”the “universal solvent” because it can dissolve a variety of compounds, ranging from sugars, salts, and proteins. This results from the water’s polarity that allow it to draw and surround ions and other polar water molecules, dissolving them and creating solutions.

Hydrogen bonds also offer water an extremely high capacity for heat, which means it can absorb and release huge quantities of heat energy without altering its temperature. This is essential for regulating temperature in living organisms as it assists in stabilizing body temperatures and preventing sudden temperatures from fluctuating.

Alongside these properties, hydrogen bonds play an important role in the biomolecule’s structure, such as proteins and DNA. The hydrogen bonds between nucleotides within DNA assist in stabilizing their double-helix shape, and the hydrogen bonds between amino acids found in proteins aid in determining their 3D structure and function.

What Is Oxygen In Water?

Oxygen in water is the oxygen dissolved (DO) in the aquatic environment. DO is the quantity of oxygen in the water that is accessible for aquatic animals to breathe. The amount of DO in water depends on various factors, including temperature and pressure, as well as any other chemicals present in the water.

Why Is Oxygen Important In Water?

Oxygen is essential for the existence of aquatic animals. Invertebrates, fish, and other marine animals need oxygen to breathe, just like humans do. If DO levels in the water are insufficient, the aquatic animals could drown and eventually cease to exist. Furthermore, oxygen is crucial to break down organic material in water, which assists in maintaining water quality.

The Effects Of Low Oxygen Levels On Water

Insufficient DO amounts in the water can cause devastating consequences for aquatic ecosystems. If DO levels fall below a certain point, the aquatic life can be suffocated, which can cause massive fish deaths and other disruptions in the ecology. In addition, low levels of DO can result in the development of harmful algae blooms that can harm both aquatic life and humans.

One of the primary reasons for the low DO levels in the water is eutrophication. It’s the process wherein excess nutrients, including nitrogen or phosphorus, are introduced into waterways and encourage an increase in algae. When algae die and die, they consume large quantities of oxygen, decreasing the DO available for other aquatic organisms.

Improving Oxygen Levels In Water

There are a variety of ways to boost the levels of oxygen in water, such as:

  1. Aeration: Aeration is the process that adds oxygen to water by causing turbulence or the process of agitation. This improves the water’s surface and allows greater oxygen to dissolve.
  2. Treatments using biological methods: The biological treatments include the addition of beneficial bacteria to water to reduce organic matter and boost DO levels.
  3. Reducing the amount of nutrient that enters waterways: Reduced levels of nutrients could prevent eutrophication and consequently decrease DO levels.

Pressure is the force per unit area of a fluid or gas exerted on an object. It measures the amount of force applied to an object and can be expressed in units such as pascals (Pa), newtons per square meter, or pounds per square inch.

Pressure can be a good way to understand the concept of force because it is a scalar. A scalar is a quantity represented by a single number and used in equations.

A scalar quantity is a constant and is independent of direction. This means that a pressure that is affecting a surface will have the same magnitude regardless of the orientation of that surface.

To demonstrate this, consider a thin flat plate in the air: when the force of air pressure is applied to the two sides of the plate, there is zero resultant force. The reason is that the forces on each side of the plate are normal to each other and point in opposite directions, so they cancel out each other.

This is also true in the case of a liquid such as water in a bucket: when the height of the water above a surface is the same for all points in the container, then there will be the same value of pressure exerted at each point.

In addition, the molecules of a gas or fluid have some kinetic energy. This kinetic energy causes the molecules to move around the fluid, and when they hit a wall or any other object in the fluid, they exert pressure.

The pressure exerted on a fluid or gas is a scalar that can be measured using an instrument such as a Pitot tube or a Kiel probe. This device can be connected to a manometer, telling you how much pressure is in a fluid or gas.
