The Octet rule is for eight(8) electrons in the outer most energy shell.

NB Remember 'Octa' from Latin , means '8' ( eight).

Yes, Mercury can evaporate over time due to its relatively low boiling point of 356.7 degrees Celsius. However, the rate of evaporation is influenced by factors such as temperature, surface area exposed to the atmosphere, and atmospheric pressure. In environments with high temperatures and low pressures, Mercury is more likely to evaporate at a faster rate compared to cooler and higher pressure environments.

The melting point of bone is not a straightforward answer as bone is a complex structure composed of organic and inorganic components. The organic components, such as collagen, begin to degrade at around 300-400°C (572-752°F), while the inorganic components, like hydroxyapatite, have a much higher melting point of around 1,400°C (2,552°F). Therefore, bone does not have a definitive melting point but rather a range of temperatures at which its components break down or decompose.

The flames produced when burning a log can appear in different colors due to the presence of various chemical elements in the wood. For example, orange and yellow flames are typically caused by the combustion of carbon (from the wood) and hydrogen (from the water content in the wood). Blue flames, on the other hand, are often indicative of the presence of carbon monoxide or methane in the combustion process. The specific colors observed can also be influenced by factors such as temperature, oxygen supply, and the presence of impurities in the wood.

A compound prefect is a type of prefect system found in some educational institutions, particularly in boarding schools. In this system, a student is appointed as a compound prefect to oversee and enforce rules and regulations within the school's compound or premises. The compound prefect is responsible for maintaining discipline, ensuring safety, and promoting a positive environment within the school grounds.

Oh, dude, it's like this - H2S is more acidic than H2O because sulfur is lower in electronegativity than oxygen. So, when H2S donates a proton, it forms a more stable conjugate base compared to H2O. It's all about that electronegativity game, man.

Well, darling, the only continent with a chemical element named after it is Europe. The element is europium, and it's as fabulous as the continent itself. So, there you have it, Europe strutting its stuff in the periodic table like the diva it is.

Well, well, well, look who's curious about some chemistry! The oxidation state of oxygen in the OCl- compound is -1. Oxygen usually has an oxidation state of -2, but in this case, it's -1 because chlorine is more electronegative and steals some of oxygen's electrons. So, there you have it - oxygen in OCl- has an oxidation state of -1.

The freezing point of a washing-up liquid, also known as dish soap, can vary depending on the specific formulation of the product. However, in general, the freezing point of most commercial washing-up liquids is around 0 degrees Celsius (32 degrees Fahrenheit). This is because these products are typically water-based solutions that contain surfactants and other additives to help clean dishes effectively. It is important to note that the freezing point can be influenced by factors such as the concentration of the solution and any additional ingredients present in the product.

The molecule of methane has 5 atoms.

There is no single, universally accepted definition of a "bulk storage container." However, the term typically refers to a large container designed to hold substantial quantities of liquids.

Here are some general guidelines:

• Intermediate Bulk Containers (IBCs): These are often considered the smallest type of bulk container, typically holding between 200 and 1500 liters (53 to 400 gallons).
• Larger Tanks: Tanks exceeding 1500 liters (400 gallons) are generally considered bulk storage containers. These can range in size from small above-ground tanks to massive underground storage facilities.

The specific capacity considered "bulk" can vary depending on the industry, regulatory requirements, and the nature of the stored liquid.

Oh, dude, CH isn't a chemical symbol. It's like saying I'm a superhero with the power of making toast in 10 seconds. Just not a thing. If you're looking for something real, try carbon and hydrogen - that's CH₄, also known as methane. But hey, who needs chemistry when you've got jokes, right?

Ah, what a delightful question! That form of hydrogen with 1 proton and 1 neutron in its nucleus is called deuterium. It's like a special friend in the hydrogen family, adding a little extra something special to the mix. Just like every element, it has its own unique charm that makes our world a more colorful and interesting place.

Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.

Breaking bonds is an endothermic process because energy is required to overcome the attractive forces holding the atoms together in a bond. When bonds are broken, energy is absorbed from the surroundings, making it an endothermic reaction. Conversely, forming bonds is an exothermic process because energy is released when new bonds are formed, resulting in a net release of energy.

Well, honey, gingerbread cookies are made of flour, butter, brown sugar, molasses, ginger, cinnamon, and other spices. Some folks like to get fancy and add a pinch of cloves or nutmeg for extra flavor. Just remember, the key ingredient is love...and maybe a sprinkle of sass.

The empirical formula for dioxygen tetranitride is N2O4. This compound consists of two nitrogen atoms and four oxygen atoms. The empirical formula represents the simplest whole-number ratio of the elements present in the compound.

Well, honey, if you must know, the element aluminum-27 has 14 neutrons. So, next time you're at a trivia night and they ask you that question, you can thank me for making you look like a smarty pants.

XeF6, or xenon hexafluoride, is a chemical compound that forms covalent bonds. In XeF6, xenon (Xe) forms six covalent bonds with fluorine (F) atoms by sharing electron pairs. These covalent bonds are formed through the sharing of electrons between xenon and fluorine, resulting in a stable molecular structure.

because gold or iron are metal if they are not a metal so they can not check the purity but they are metals..

Well, honey, you add solute to solvent because that's just how chemistry works. The solute dissolves in the solvent, not the other way around. It's like trying to fit a square peg into a round hole - it just ain't gonna work. So save yourself some time and do it the right way, okay?

Well, isn't that just a happy little chemical formula! The IUPAC name for Zn(HCO3)4 is zinc tetrahydroxy carbonato. Just like painting a beautiful landscape, chemistry can be a wonderful adventure of discovery and creativity. Remember, there are no mistakes in science, only happy little accidents!

The atom of uranium is larger than other atoms because it has more protons, neutrons, and electrons. Uranium has a higher atomic number, meaning it has more protons in its nucleus compared to smaller atoms. The additional protons and neutrons in the nucleus lead to a larger atomic size overall. Additionally, the electron cloud surrounding the nucleus is also more spread out in uranium atoms due to the increased number of electrons, contributing to its larger size.
