Chemical vocabulary
acid - There are several ways to define an acid, but they include any chemical that gives off protons or H+ in water. Acids have a pH less than 7. They turn the pH indicator phenolphthalein colorless and turn litmus paper red.
acid anhydride - An acid anhydride is an oxide that forms an acid when it is reacted with water. For example, when SO3- is added to water, it becomes sulfuric acid, H2SO4.
actual yield - The actual yield is the amount of product you actually obtain from a chemical reaction, as in the amount you can measure or weigh as opposed to a calculated value.
addition reaction - An addition reaction is a chemical reaction in which atoms add to a carbon-carbon multiple bond.
alcohol - An alcohol is any organic molecule that has an -OH group.
aldehyde - An aldehyde is any organic molecule that has a -COH group.
alkali metal - An alkali metal is a metal in Group I of the periodic table. Examples of alkali metals include lithium, sodium, and potassium.
alkaline earth metal - An alkaline earth metal is an element belonging to Group II of the periodic table.
Examples of alkaline earth metals are magnesium and calcium.
alkane - An alkane is an organic molecule that only contains single carbon-carbon bonds.
alkene - An alkene is an organic molecule that contains at least one C=C or carbon-carbon double bond.
alkyne - An alkyne is an organic molecule that contains at least one carbon-carbon triple bond.
allotrope - Allotropes are different forms of a phase of an element. For example, diamond and graphite are allotropes of carbon.
alpha particle - An alpha particle is another name for a helium nucleus, which contains two protons and two neutrons. It's called an alpha particle in reference to radioactive (alpha) decay.
amine - An amine is an organic molecule in which one or more of the hydrogen atoms in ammonia have been replaced by an organic group. An example of an amine is methylamine.
base - A base is a compound that produces OH- ions or electrons in water or that accepts protons. An example of a common base is sodium hydroxide, NaOH.
beta particle - A beta particle is an electron, although the term is used when the electron is emitted in radioactive decay.
binary compound - A binary compoundis one made up of two elements.
binding energy - Binding energy is the energy that holds protons and neutrons together in the atomic nucleus.
bond energy - Bond energy is the amount of energy required to break one mole of chemical bonds.
bond length - Bond length is the average distance between the nuclei of two atoms that share a bond.
buffer - A liquid that resists change in pHwhen an acid or base is added. A buffer consists of a weak acid and its conjugate base. An example of a buffer is acetic acid and sodium acetate.
calorimetry - Calorimetry is the study of heat flow. Calorimetry may be used to find the heat of reaction of two compounds or the heat of combustion of a compound, for example.
carboxylic acid - A carboxylic acid is an organic molecule containing a -COOH group. An example of a carboxylic acid is acetic acid.
catalyst - A catalyst is a substance that lowers the activation energy of a reaction or speeds it up without being consumed by the reaction.
Can you give example how we use that vocabulary in chemistry lesson?
BalasHapusHi laras. Can you explain about reagen?
BalasHapusReagents or also known as Reactan is a term that is often used in the chemical world. Reagents have many uses and most involve lifesaving applications. Substances or two substances make, measure or build up the existence of chemical reactions with the help of reagents. Organic chemistry may also define reagents as mixtures or different substances that will make changes to the substrate under certain conditions.
HapusCan you give examples of binary compounds, binding energies, and bonding energies?
BalasHapusThe binary compound name of the two non-metallic types is a series of names of both element types with the suffix ida in the second element name.
BalasHapusExample:
• HCl = hydrogen chloride
• H2S = hydrogen sulfide
What is anhydride acid and berian example!
BalasHapusAcid anhydride is an organic compound having two acyl groups attached to the same oxygen atom.
HapusWhat are the buffer functions for the body and in everyday life?
BalasHapusThe pH of blood in the body of a living thing is always around 7.4. This is because all body connections are buffer solutions that keep blood pH constant during metabolism. The buffer solution present in human and animal blood plasma can be proved. If into 1 L normal blood (pH = 7.4) is inserted 0.01 mol HCl, its pH is changed to 7.2 (decrease 0.2). In fact, if 0.01 mol HCI is inserted into 1 L isotonic solution with blood, such as NaCI solution, the pH of the solution changes from 7.0 to 2. Therefore, various drugs are introduced into the body such as injectable fluids, intravenous fluids , And eye drops are made to approach the pH of body fluids. Buffering solutions that play a role in the human body include buffer hemoglobin, carbonate buffer, and phosphate buffer.
