Acid is added to a beaker containing crushed marble. What effect does stirring this mixture have on the system?

Answer 1

Well, this is an observation for an experiment that you have done recently, and we have not.....

Stirring the slurry should tend to break up the marble chunks and release carbon dioxide gas, right?

#CaCO_3(s) + 2HCl(aq) rarr CaCl_2(aq) + CO_2(g)uarr#

In any case, if you haven't completed the experiment yet, kindly watch carefully and note the outcomes as soon as possible.

By speeding up the rate of dissolution and encouraging more thorough mixing, stirring the mixture improves the reaction between the acid and crushed marble.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
