Adjust the alkalinity from 70 ppm to 100 ppm in a 250.000 gallon pool using sodium bicarbonate

Polygon is ur

Using dilution equationm1v1 =m2v2 ; where m1 and m1 are the intiial and final concentration, and v1 and v2 are the initial and final volume.5  × 5 m = 8 l  × m2m2 = 25/8 = 3.125 mtherefore; the resulting molarity is 3.125 m

Ihave no idea, youre outta luck

Ionic compounds are compound formed after a result of ionic bond which involves transfer electrons between atoms where one atom gains electrons and the other looses electrons. ionic compound only conducts electricity in liquid form (when dissolved in water or melted) when their ions are free to move. in solid state the compounds can not conduct since the ions are not free to move. therefore, the answer is (4) the solid is a poor conductor while the liquid is a good conductor.
