CuSO4 (s) vs CuSO4 (aq) Copper sulfate is also known as cupric sulfate. Copper sulfate is a salt of copper +2 ion and sulfate anion. When a copper +2 solution and a sulfate solution (potassium sulfate) are mixed together, a copper sulfate solution will result. Copper sulfate has several types of compounds, which differ […]
Carboxylic Acid vs Ester Carboxylic acids and esters are organic molecules with the group –COO. One oxygen atom is bonded to carbon with a double bond, and the other oxygen is bonded with a single bond. Since only three atoms are connected to the carbon atom, it has a trigonal planar geometry around it. […]
钠原子与钠离子在仙女的元素odic table are not stable except the noble gases. Therefore, elements try to react with other elements, to gain the noble gas electron configuration to achieve stability. Likewise, sodium also has to get an electron to achieve the electron configuration of the noble gas, Neon. […]
Covalent vs Polar Covalent As proposed by the American chemist G.N.Lewis, atoms are stable when they contain eight electrons in their valence shell. Most of the atoms have less than eight electrons in their valence shells (except the noble gases in the group 18 of the periodic table); therefore, they are not stable. These […]
H2O vs H2O2 | Water vs Hydrogen Peroxide Properties, Usage, Difference Water (H2O) and hydrogen peroxide (H2O2) are molecules of oxygen and hydrogen elements. Water H2O, which is known to all as water, is something without which we cannot live. Two hydrogens are covalently bonded to oxygen to form water. The molecule gets a bent shape […]
pH vs pKa We normally identify an acid as a proton donor. Acids have a sour taste. Lime juice, vinegar are two acids we come across at our homes. They react with bases producing water, and react with metals to form H2; thus, increase metal corrosion rate. The ability to donate a proton is […]
Salt vs Sodium | Sodium vs Sodium Chloride | Properties, Usage Sodium is a vital element in our body. The daily dosage of sodium needed for a healthy body is 2,400 milligrams. People take up sodium in their diet in different forms, and the main sodium source is salt or sodium chloride. Sodium Sodium, which symbolized as […]
Mass Number vs Atomic Mass Atoms are mainly composed of protons, neutrons and electrons. Some of these sub particles have a mass; therefore, they contribute to the total mass of the atom. However, some sub atomic particles like electrons do not have a significant mass. For each isotope of an element, there is a […]
Intensive Properties vs Extensive Properties Almost everything around us can be taken as a matter. We can define matter as things, which consist of atoms and molecules, and have a mass and a volume. Mainly, we divide them into four classes as solid, liquid, gas and plasma. Solids have a definite shape and a […]
Effective Nuclear Charge vs Nuclear Charge Atoms are mainly composed of protons, neutrons and electrons. Nucleus of the atom contains protons and neutrons. And there are electrons circling around the nucleus in orbitals. Atomic number of an element is the number of protons it has in the nucleus. The symbol for denoting the atomic […]
