Even though most of us have never seen it, ammonia is all around us. It’s a compound of nitrogen and hydrogen, and it’s found in everything from animal waste to household cleaners. Ammonia is also a key ingredient in agricultural fertilizers, as it helps to promote plant growth. Ammonia is a colorless, highly corrosive gas …
When a chemical bond is broken, the overall change in enthalpy (heat) of the system must be determined to identify whether the process is endothermic or exothermic. In endothermic reactions, enthalpy is absorbed from the surroundings in order to break the bonds, resulting in a net heat gain for the system. For exothermic reactions, enthalpy …
ionic bonds are non-directional, meaning that they don’t have a specific orientation. This is in contrast to covalent bonds, which do have a specific orientation. Because of this, ionic compounds tend to be regular in shape. This is why table salt, for example, is made up of cubic crystals. Ionic bonds play an important role …
Covalent compounds are found in many items we use every day. Water, for example, is a covalent compound made up of two hydrogen atoms and one oxygen atom. In addition to being found in food and drink, covalent compounds are also found in many household cleaning products. For example, bleach is a covalent compound that …

Ionic bonds are found throughout the world, in both living things and non-living things. In the human body, ionic bonds help to hold cells together. In fact, many of the structures in our bodies, including our bones and teeth, are made up of compounds that contain ionic bonds. Ionic bonds are also responsible for the …
Wood has been used by humans for centuries, and it is easy to see why. It is strong and durable, yet relatively lightweight, making it ideal for everything from construction to furniture-making. In addition, wood is an excellent insulator, both of heat and sound. It is also a renewable resource, meaning that it can be …

The structure of an atom consists of a nucleus composed of protons and neutrons with electrons orbiting around this nucleus. Electrons are much smaller than protons and neutrons and are attracted to the nucleus by electromagnetic force. This force also holds the nucleus together despite the fact that the protons are all positively charged and …

Condensation is the process of water vapor turning into liquid water. It can happen when warm air meets cold surfaces, such as a glass of ice water on a hot day. When the temperature of the air gets too low, the water vapor in the air turns into tiny droplets of liquid water, which we …
[Solved] – Is Condensation Exothermic or Endothermic Read More »
The process of converting matter from one form to another is a central concept in chemistry. Matter can exist in different states, including solid, liquid, and gas. The state of matter is determined by the strength of the forces between the particles that make up the substance. For example, the particles in a solid are …
You might not realize it, but evaporation plays a big role in your daily life. When you take a shower, the water on your skin evaporates, cooling you down. When you sweat, the water in your sweat evaporates, helping to regulate your body temperature. And when you look out over a lake on a hot …
