In order to understand endothermic reactions, you need to know about endothermic graphs. This graph shows how the heat energy changes during an endothermic reaction. An endothermic graph is a graph that shows how much heat is being absorbed by a system over time. It starts with a high amount of heat energy, and then …
Full List of Strong 22 Acids and Strong Bases Do you know what the strongest acids and bases are? Let’s go through a list of some of the strongest acids and bases that are known to man. This information can be useful if you are looking for strong acids or bases to use in your …
The Molar Mass Of Oxygen (O2) Oxygen is a colorless, odorless gas that is essential for human life. The molar mass of oxygen (O2) is 32 grams per mole. This means that there are 32 grams of oxygen in every mole of the gas. The molar mass of oxygen is 32 grams per mole. What …
Light Energy Examples What are examples of light energy? Light energy is a type of electromagnetic radiation that travels through the air and is visible to the human eye. It is produced by the sun and other stars, and it can be used to power devices or light up spaces. Light energy is the form …
An exothermic reaction is a chemical reaction that releases heat. This can be seen in the exothermic graph, which shows the amount of heat released over time. The exothermic graph is important for understanding how chemical reactions work, and it can also be used to improve safety procedures. Let’s review the details of an exothermic …
Urea vs uric acid – two compounds that are often confused with each other. They have similar names, and they both come from the breakdown of proteins in the body. However, they have different functions and occur in different parts of the body. Let’s go over the differences between urea and uric acid, and how …
Nucleotide vs nucleoside – both important parts of DNA and RNA. They play different roles in these molecules, however, so it’s important to understand the difference between them. Major Differences Between Nucleotide vs Nucleoside The key differences between nucleotides and nucleosides are: Nucleotides: Nucleosides: So in summary, nucleotides contain phosphate groups while nucleosides do not. …
Many people believe that fish can breathe underwater because they see them swimming around in lakes and oceans. However, the truth is that fish need oxygen to survive, just like humans do. We will also talk about what happens when there is not enough oxygen in the water. Do fish need oxygen? Yes, fish absolutely …
The answer is that HCl, or hydrochloric acid, is a covalent compound. HCl (hydrochloric acid) is an ionic compound consisting of hydrogen cations (H+) and chloride anions (Cl-). The bond between hydrogen and chlorine in HCl is a polar covalent bond, but HCl dissociates completely into ions when dissolved in water. 6 key points explaining …
What are iron valence electrons? The number of valence electrons in an iron atom (Fe) is 8. Iron has 8 total valence electrons. Valence electrons are the outermost shell electrons that are responsible for determining how the atom will react with other atoms and hence, their chemical properties. Iron (Fe) is a transition metal located …
Do you know where the metals are located on the periodic table? If not, you’ve come to the right place. Let’s answer where the metals can be found on the periodic table. Metals are primarily found on the left side and in the middle of the periodic table. Here is an overview of where metals …
The 7 key differences between osmosis and diffusion are: So in summary, osmosis is a specialized type of diffusion specifically describing the movement of water molecules across a semipermeable membrane in order to equalize solute concentrations on both sides. Osmosis and diffusion are two types of transport processes. Osmosis is the movement of water molecules …
