A tapping vessel opens in a tank like side. the tank has an outel for water on the upper side & a water inlet on the lower side. finely ground ore is introduce in the tank from lower side & gangu particles & pure are separated by this method. 1. The above description is of which gravitation separation method.

2.draw labelled diagram of this method.​

0.2348 grams of pbcl2 used to form 44.0 ml of solution.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution

Afusion reaction takes place between carbon and another element. neutrons are released, and a different element is formed. the different element is a) lighter than helium.b)heavier than helium.c)the same weight as helium.d)dependent on the element that reacted with carbon.
