CaCO3 is the chemical formula of calcium carbonate.
The chemical formula of methane is CH4
The chemical formula of sulphuric acid is H2SO4 .
Kossel and Lewis in 1916 Developed the theory for the bond formation after watching the behavior of noble gases. The noble gases were inert in behavior and do not react with any substance. Kossel and Lewis found that the Octateof noble gases was complete so they do not react. They gave the theory that the
Physical and chemical changes are associated with energy changes. For this we have to understand the type of changes. 1. Exothermic :- These are the changes that release energy when they occur . 2. Endothermic :- The changes that occur by absorbing the energy are the endothermic . In case of chemical change the reaction
The catalyst is a substance that increase the rate of reaction without getting consumed in a chemical reaction. It is recovered as it is after the reaction. The catalyst increase the rate of reaction by following two ways :- 1. The catalyst provide the surface area for the reactants to react easily. 2. The catalyst
The precautions must be taken while dilution. And it has to be taken care of that it is to be done only by the experts. We have to be strict and stick to the statement , ” Always add acid to water while dilution”. The dilution of acid is a highly exothermic process . Now
The chemical name of Cu2CO3 is Copper(II) carbonate and it is also named as Cupiric carbonate .
The chemical formula of hydrochloric acid is HCl.
Chemical symbols :- These are the symbols that are used to depict a specific element. Like N is the symbol of Nitrogen, Fe is the symbol of Iron, C of Carbon, Zn of Zinc and O of Oxygen. Chemical formula :- These formulas give us information of a molecule that how many atoms of a
The arrow in between the chemical equation is an important part of the equation. It depicts that the reactants are converted into products. Or in simple language we can say it shows the conversion of reactants into products. On its left hand side are the reacting species and on its right hand side are the
We can increase the rate of chemical reaction by 1. Increasing the temperature of reaction mixture . 2. If there is a reduction in volume then we can increase the rate of reaction by applying pressure . 3. We can increase the risk of rejection by adding suitable catalyst .
Digestion is a process in which complex food molecules are broken down into simple molecules that can be taken up by the body. During digestion Sugar is converted into glucose , Oils and Fat is converted into fatty acids , Proteins are converted into amino acids . Sugar substances formed from the complex molecules are
In a physical change the nature of substance remains same . The properties remains same. But in case of chemical change the new kind of substance is formed, with different nature. “Sublimation is a process in which a substance changes its state from solid into vapour directly”. So the point to note here is that
the group contains elements with similar properties.
The formula for 4-nonene is CH3CH2CH2CH=CHCH2CH2CH2CH3 .
H2SO4 is the formula for sulphuric acid.
The formula of binary ionic compounds is written by following some rules and these must be followed. Firstly the positively charged ion, Cation is written first and then the negatively charged, Anion is written. After this the corresponding number of ions are written as the subscript. For example CaCl2 and NaCl. Lets see how the
The chemical formula of carbon monooxide is CO , which means that in a molecule of carbon-monooxide there is one atom of Carbon and one atom of oxygen.
The electrons participate in chemical bonding. basically every bond formation is due to the reason that every element tends to complete its octet (outer shell). “atoms can combine either by transfer of valance electrons from one atom to another or by sharing of valence electrons in Order to have a complete octet or the configuration
The chemical formula for hydrogen peroxide is H2O2 it means that in its 1 molecule , there are 2 atoms of Hydrogen and two atoms of oxygen.
During a chemical reaction new substances are formed with different properties. The total mass and number of atoms remain same , only the rearrangement of atoms take place. Lets take an example of formation of water from hydrogen and oxygen. The point is , that the hydrogen is an explosive gas and oxygen is essential
