Characteristic properties distinguish one substance is from another substance; intensive properties is an inherent attributes that do not change with the amount of matter, for example the boiling point of water is always 100°C at standard pressure, regardless of the amount; chemical properties describe how a substance interacts with other substances through chemical reactions, and … Read more
The animal kingdom includes mollusks, and they exhibit a diverse range of circulatory systems. Cephalopods, a class of mollusks which include squid and octopuses, have a closed circulatory system, it is an efficient system that allows for a higher metabolic rate to support their active lifestyle. Unlike the open circulatory systems found in most other … Read more
In a right triangle, the hypotenuse represents the side that is opposite the right angle. Pythagorean Theorem states the square of the hypotenuse’s length equals to the sum of the squares of the lengths of the other two sides. So, the hypotenuse is always the longest side because the sum of two squares must always … Read more
Lewis dot structure represents valence electrons arrangement around an atom and molecules. Hydrogen monofluoride or hydrofluoric acid (HF) molecule is a diatomic molecule. Diatomic molecules such as HF held together by a single covalent bond. Single covalent bond in HF is formed by sharing a pair of electrons between hydrogen atom and fluorine atom. Ever … Read more
The real rate of return represents the actual profit made from an investment. Investment returns is usually expressed as a nominal rate. However, the nominal rate does not account for inflation. The real rate of return measures the investment’s increase in purchasing power. Therefore, investors and economists use it to evaluate investments accurately. The Silent … Read more
Rivers are large natural streams, streams are small natural watercourses, flow rate is the speed of water movement, and the ecosystem describes the community of living organisms interacting with each other and their environment. Rivers exhibit larger flow rate. Streams exhibit smaller flow rate. The ecosystem inhabiting streams is often more sensitive to changes. The … Read more

Recognizing strong acids from a list needs understanding of acid properties. Acid strength is the ability of an acid to donate a proton (H⁺) in solution. Strong acids completely dissociate into ions when they are dissolved in water, and this behavior differentiates them from weak acids, which only partially dissociate. Identifying which acids do not … Read more
