If all of the 0.1699 moles of BaCl2 were to be used in the reaction it would require 2 x 0.1699 = 0.3398 moles of AgNO3 for the reaction to go to completion. There are only 0.24489 moles of AgNO3 available which is less than the required 0.3398 moles.
If all of the 0.24489…
Indicate a potential reaction between electrolyte solutions where NOTHING happens, no change in temperature, no gas evolved, no precipitate, thus, no evidence of ions interacting and changing partners.
A powder of calcium carbonate can be taken and added with hydrochloric acid. This leads to the evolving of gas bubbles. These gas bubbles can be tested by either by passing it through lime water which will give a white precipitate. Or a lighter splinter can be introduced into the test tube. This splinter will go off immediately because of the carbon dioxide ...

The waste can harm humans, animals, and plants if they encounter these toxins buried in the ground, in stream runoff, in groundwater that supplies drinking water, or in floodwaters, as happened after Hurricane Katrina.
One mole of beryllium weighs 9 grams, therefore we have 0.1 mole of beryllium if the mass is 0.9, one mole of oxygen weighs 16 grams therefore we have 7.3/16 moles of oxygen and finally we have 4.5 grams of aluminium therefore we have 4.5/27 moles of aluminium.
