Consider the following balanced chemical equation, kcl(aq) agno3(aq) → agcl(s) kno3(aq)when a sample of impure potassium chloride (0.900 g) was dissolved in water, and treated with excess silver nitrate (agno3), 1.26 g of silver chloride (agcl) was precipitated. calculate the percentage kcl in the original sample.

Why is the structure of molecule important to its function?

A2.5% (by mass) solution concentration signifies that there is a 2.5 % (by mass) solution concentration signifies that there is blank of solute in every 100 g of solution. of solute in every 100 g of solution

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
