Cambridge IGCSE Chemistry guide has a lot of specifics commonly used in Cambridge Chemistry. The terms used in Cambridge Chemistry have proper definitions. These definitions are commonly used in Cambridge IGCSE Chemsitry. 1. Define the term proton number: The number of protons in the nucleus of an atom 2. Define the term acid: A proton…
What is true about all uranium atoms? Uranium is an element that has some specifics or special properties for example it was the first element used by Alert Einstein in the nuclear bomb production. Yes, it is radioactive but is that all we know about uranium atoms? Not really, I am going to show you…
What is Nuclear Chemistry? Nuclear Chemistry is the chemistry and reactions involving the nucleus of an atom. Nuclear reactions tend to release a lot of energy than normal chemical reactions. Nuclear reactions involve splitting the nucleus of a heavy atom(nuclear fission), coming together of smaller nuclei(nuclear fusion), or even changing the protons in a nucleus(artificial…
This is a complete guide to IGCSE alternative to practical chemistry and I have broken it down into several sections just to help us understand what is required in this section. Please remember in IGCSE Olevel chemistry, there are three sections. We have the essay(theory), objectives, and alternative to practical or Practical. The mark distribution…
Catalyst in Chemistry is defined as a substance that alters the rate of a chemical reaction but remains unchanged at the end of the reaction. A catalyst is a substance that speeds up the rate of reactions but it does that by affecting the activation energy of the reaction. Activation energy is the minimum amount…
What is an acid? Acid is mostly taken by Arrhenius definition as a substance that dissolves in water to produce hydrogen ion as the only positive ion. This definition holds true in all cases though acid can be defined and explained using other different concepts.. However, I will talk about Acids, Bases, and Salts in…
Balancing Chemical Equations involves understanding concepts and learning basic skills required in Chemistry. Though balancing chemical equations is very simple however it requires practice. Chemical equations are required to be balanced because a balanced chemical equation demonstrates and verifies the law of conservation of mass or matter. The law of conservation of matter states that…
Resonance in Chemistry is otherwise called Mesomerism simply refers to the alternation or rotation of double bonds in some compounds which ensure their stability. Resonance in Chemistry is a term used to describe the representation of the covalent bonding in some compounds like Benzene, Carbon IV oxide, and even Ozone. Additionally, resonance exists in ions…
Performing experiments in the laboratory require skills and perfection, I have composed a list of 50 chemistry lab equipment and their uses in the laboratory. This is a guide on the list of lab pieces of equipment and their uses. This is the same as saying use of apparatus used in Chemistry. There are different…
Le Chatelier’s principle and chemical equilibrium is a concept that is usually discussed in Chemistry. Some chemical reactions are reversible and can attain equilibrium. Chemical equilibrium is a state of a system (i.e chemical reaction) when the rate of forward reaction equals the rate of backward reaction. Please recall that a reversible reaction is a…
