What is the smallest reading of vernier caliper? The smallest reading that a vernier caliper can measure is called the least count. The value of... View Article
How do you find the electric field between two plates? The magnitude of the charge on each plate, Q = CV Here, C is the capacitance of the... View Article
Sodium Chloride (NaCl) is a pure ionic compound and not a covalent compound. The two atoms transfer their electrons to form ions, Na+ and Cl-.... View Article
NaCl (Sodium Chloride) is formed due to ionic bonding, when the atoms Na and Cl transfer their electrons giving rise to ions such as Na+ and Cl-.... View Article
The main difference between ionic and covalent bonding is that ionic bond is formed between two ions and covalent bond is formed between pair of... View Article
Non polar covalent bonds are strong. The electrons are shared between two atoms equally, hence the number of electrons shared in both the atoms... View Article
Hydrogen bond is not a covalent bond but a dipole-dipole attraction between the molecules. It is a special case of intermolecular attractive... View Article
CO2 is not a coordinate covalent bond since none of the atoms (Carbon and Oxygen) donates both the electrons in the shared pair. But a coordinate... View Article
Covalent bonding occur between two non-metallic atoms or molecules. They have definite shape as well as low melting and boiling points. At room... View Article
CaCl2 or Calcium Chloride is an ionic bond and not a covalent bond. Since there should be sharing of electrons between two atoms to be a covalent... View Article
The ideal gas equation is given by: PV=nRT where R is the universal gas constant whose value is equal to 8.314 kJ/mol.K P is the pressure of... View Article
Barium (symbol:Ba) is the group 2 or alkaline earth metal that has the largest atomic radius, equal to 222 pm. Atomic number of Barium is 56.... View Article
Group 2 elements in the modern periodic table are called alkaline earth metals. They are Beryllium (Be), Magnesium(Mg), Calcium (Ca), Strontium... View Article
Hydrogen Sulphide (H2S) is a weak acid that gets slightly dissolved in water, producing the hydrosulphide ions HS-. Therefore, H2S is also... View Article
