Calculate the mass and charge of 1 mole of electrons.
The electric charge required for electrode deposition of one gram-equivalent of a substance is :
Which is bigger, a coulomb or charge ona n electron?
Find the charge in coulombs on 1g ion of N^(-3)
STATEMENT-1 : Equivalent volume of H_(2) is 11.2 L at 1 atm and 273 K. STATEMENT-2 : 1//2 mole H_(2) has produced when 1 mole of H^(+) (aq) accepted 1 mole of e^(-) .
each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : STATEMENT-1: A colloid gets coagulated by addition of an electrolytes. STATEMENT-2: Coagulation depends on the valance and sign of the charge of the coagulant ion.
Can a metal sphere of radius 1 cm hold a charge of 1 C?
