What is the chemical formula of Kajal?
Studies revealed that kajal comprises of galena (PbS), minium (Pb3O4), etc. Prolonged application may cause excessive lead storage in the body, causing convulsions and anaemia. [22] In the present study, 93.9% of mothers are practising kajal application to eyes.
What is the unit of molar conductivity?
siemens metres squared per mole
The SI unit of molar conductivity is siemens metres squared per mole (S m2 mol−1).
What is formula of molar conductivity?
(ii) Molar conductivity: At definite temperature the conductivity of ions in a solution containing one gm mole of electrolyte is called molar conductivity. It is denoted by μ or Λm Formula: Λm=κ×V.
What is the formula of equivalent conductance?
Answer: The term ‘equivalent conductance’ can be defined as the net conductance of every ion that is produced from one gram equivalent of a given substance. V = Volume (in millilitres) that contains one gram equivalent of the given electrolyte.
What is antimony kohl?
Kohl Ithmid (also known as Antimony) from SunnaHealing UK, was used by the Prophet Muhammad ﷺ on his eyes and is a very popular product from the Sunnah. Ibn al-Qayyim رحمه الله said: “Kohl protects the health of the eyes and gives strength and clarity of vision, and cleanses they eye of bad substances.
What is kohl powder?
Kohl is a black powdery substance made from galena, an ore that is the source of the mineral lead. Galena ore was found near the Nile River at the city of Aswan, in present-day southeast Egypt, and on the banks of the Red Sea, among other places.
What is the unit of conductance?
siemens
siemens (S), unit of electrical conductance. In the case of direct current (DC), the conductance in siemens is the reciprocal of the resistance in ohms (S = amperes per volts); in the case of alternating current (AC), it is the reciprocal of the impedance in ohms.
What is unit of conductance?
Electrical conductance, G, is the reciprocal of resistance (R): G=1R. Electrical conductance measures how easily electricity flows through electrical components for a given voltage difference. The SI unit of conductance is siemens (the older unit was the mho).
What is the unit of conductivity?
Siemens per meter
Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is Siemens per meter (S/m).
What are the units of equivalent conductance?
ohm−1cm(g−eq)−1.
