  Istilah "Pelarut/Solvent" mengacu pada kelas senyawa kimia yang dijelaskan berdasarkan fungsi - istilah ini berasal dari bahasa Latin, yang secara kasar berarti "melonggarkan." Dalam kimia, pelarut/solvent - yang umumnya dalam bentuk cair - digunakan untuk melarutkan, menangguhkan atau mengekstrak bahan lain, biasanya tanpa mengubah secara kimia baik pelarut/solvent atau bahan lainnya. Pada umumnya zat yang digunakan sebagai pelarut adalah air (H2O), Selain air yang berfungsi sebagai pelarut adalah alkohol, amoniak, kloroform, benzena, minyak, asam asetat, akan tetapi kalau menggunakan air biasanya tidak disebutkan. Densitas adalah pengukuran massa setiap satuan volume benda. Semakin tinggi densitas (massa Jenis) suatu benda, maka semakin besar pula massa setiap volumenya. Densitas dapat menjelaskan mengapa benda memiliki akuran yang sama namun beratnya berbeda. Jadi Densitas berbanding lurus dengan massa dan berbanding terbalik dengan volume benda. Padatan umum...
Maksud dari homogen berarti yang larut sempurna, ya. Contohnya garam. Jika garam dimasukkan ke dalam air maka disebut zat terlarut. Hasilnya si garam akan melebur dan homogen dengan air.Selain itu, air gula dapat disebut larutan karena ketika gula larut dalam air dan melebur, maka larutannya sama sehingga bersifat homogen. Larutan didefinisikan sebagai suatu campuran homogen yang terdiri dari dua atau lebih zat dalam komposisi yang bervariasi. L arutan dapat terbentuk dari berbagai kombinasi zat, seperti gas dalam gas, gas dalam cairan, cairan dalam cairan, padatan dalam cairan, padatan dalam padatan, dan sebagainya.

Human Reproductive System: Organs, Anatomy, Functions, and Diseases

IBYXO - Humans have many organs, one of which plays a role in the reproductive system. This reproductive system is used for the process of forming new individuals. Every living thing will reproduce for the continuation of its kind. Likewise with humans, experiencing reproduction for their survival. To explain everything, see the material below. The Human Reproductive System A. Reproductive Organs Reproduction is the process of forming new individuals. Reproduction aims to preserve the species from extinction. Reproduction in humans is classified as sexual reproduction. The human reproductive system involves a male parent and a female parent. In the human reproductive system, each parent has reproductive organs. The human reproductive system will begin to function when a person reaches maturity (puberty) or puberty. In a man, his testes have been able to produce male genital cells (sperm) and the hormone testosterone. While a woman's ovaries have been able to produce eggs (ovum) and...

Scientific Performance

IBYXO - We always see a lot of living things on the surface of this earth and very diverse, ranging from large & small to those that cannot be seen with our senses. However, living things that cannot be seen with our senses can actually be studied in several ways in scientific performance, here is the explanation. A. Scientific Work If someone wants to know something through observation, it will not work well if the observation is made without going through planned and systematic steps or methods to obtain information on biotic and abiotic natural phenomena. Biotics are living parts of nature, while abiotics are inanimate natural objects The most appropriate step or method used in observation is the scientific method. The scientific method is a tool to solve problems, find out the causes so that it has a reasonable and reliable conclusion. For this reason, the scientific method and scientific attitude are used by someone in making observations. The steps of the scientific method ar...

Substance - Properties and Changes

IBYXO - Something that occupies space and has mass is a substance, the objects around us are never separated from the name of the substance.  These objects can change from one form to another. For example, heated water will change its form from liquid to water vapor. Surely many are wondering about that, here's an explanation of substance changes. A. Properties of Substances 1. Physical Properties Substances have their own characteristics. You can bend a copper wire easily, while an iron bar is difficult to bend. The characteristics of a substance that can be observed without changing the substances that make up the material are called physical properties. The physical properties of an object include: a. Form of Substance  Three kinds of forms of substances that we know are: solid, liquid and gas. The substance can change from one form to another. Some of the changes we are familiar with are: evaporating, condensing, melting, freezing, sublimating, and crystallizing. Substance...

Elements, Compounds & Mixtures

IBYXO - Every object in nature has its own form ranging from solid, liquid, and gas, but this object is not formed without natural classification. The surrounding objects are formed due to the existence of elements, compounds, and mixtures. This time we will discuss some information about elements, compounds, and mixtures, here is the explanation. A. Elements Elements consist of metals and non-metals. Pure substances have properties that distinguish them from other substances. For example, the element hydrogen is composed only of hydrogen atoms. The element oxygen is only composed of oxygen atoms only. The properties of oxygen and hydrogen do not appear in substances formed from both, for example water (H₂O).  In nature there are 92 types of natural elements, while the rest are artificial elements. The total number of elements in nature is approximately 106 types of elements. Elements are grouped into three (3) parts, namely: 1. Metallic elements In general, metal elements have shi...

Excretory System: Definition, Function, Organs, Abnormalities, and Diseases

Gambar
IBYXO - The human body consists of many important organs, but we are never free from diseases both from within the body and from outside the body, in the human body itself there is an excretory system which is very important to remove the waste produced by our body. This time we will discuss the excretory system, some of the things described below are only a small part of the information that can be provided about the excretory system. Definition and Function of the Excretory System The excretory system is an organ system that functions to remove waste substances in the body as a result of metabolic waste in the body. The rest of the metabolism released through excretion is called excreta. Excretes can be in the form of water and the substances dissolved in it, mineral salts, and bile pigments that are excreted with urine and sweat. The excretory system is as important as the digestive system, because in addition to functioning to remove waste from the body, the excretory system also h...
