A solubilidade do cloreto de sódio é de 38g por cada 100 de água, a 20ºC. Adicionou-se 38g deste sal a 50g de água. Calcula a massa de cloreto de sódio que não se dissolveu.

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst

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
