If you’ve ever taken a chemistry class, you’ve probably heard the term “molar mass.” It can sound complicated, but it’s really just a special way of weighing atoms and molecules. So, what is the molar mass of oxygen? The simple answer is: the molar mass of oxygen gas (O₂) is approximately 32 grams per mole …
In the world of chemistry, not all acids and bases are created equal. Some are incredibly powerful, while others are much milder. This guide provides a clear, simple list of strong acids and strong bases to help you understand these fundamental chemical concepts. The key difference between strong and weak lies in how they behave …
Have you ever used an instant cold pack and wondered how it gets cold all by itself? The answer is a fascinating process called an endothermic reaction, and the best way to understand it is with an endothermic graph. An endothermic reaction is a type of chemical reaction that absorbs heat energy from its surroundings, …
Understanding The Many Light Energy Examples Have you ever stopped to think about how you can see the world around you? Or how plants grow? This is all thanks to light energy! Light energy is all around us, from the sun in the sky to the screen you’re reading this on. Light energy is a …
Exothermic Reactions and Their Exothermic Graphs Imagine you’re holding a firework sparkler on the Fourth of July. You can feel the heat radiating from it, right? That’s because the sparkler is undergoing an exothermic reaction – a chemical reaction that releases heat! Lots of things around us involve exothermic reactions, from a burning candle to …
Comparing Urea vs Uric Acid: Exploring Our Health Indications Ever wonder what happens to the protein from that chicken sandwich you ate? Your body is a recycling expert! It breaks down protein into useful parts and creates some waste products. Your body makes two specific waste products named urea and uric acid. They sound pretty …
In this article we will compare Nucleotide vs. Nucleoside. Nucleotides and nucleosides are both essential parts of DNA and RNA, which are crucial for all living things. Purines and pyrimidines are the two categories of nitrogenous bases found in these molecules. Understanding the difference between nucleotide and nucleoside helps clarify their roles in biological processes. …
Many people wonder, “Do fish need oxygen to survive?” The answer is yes! Fish need oxygen just like humans do. They live in water, but that doesn’t mean they don’t need oxygen to breathe. Let’s explore how this works and why oxygen is super important for fish. How Fish Breathe Fish have a special breathing …
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 …
