Describe the process and write out the balanced chemical equation for the reaction that occurs when solid calcium carbonate reacts with hydrochloric acid to form aqueous calcium chloride, carbon dioxide, and water. What type of reaction is this, and what observations might indicate that the reaction is taking place?

Of course , I ' d be happy to help ! � � � � \n The reaction between solid calci um carbon ate ( Ca CO 3 ) and hydro ch lor ic acid ( H Cl ) is a neutral ization reaction , which is a type of chemical reaction where an acid and a base react to form a salt and water . The bal anced chemical equation for this reaction is : \n Ca CO 3 ( s ) + 2 H Cl ( a q ) → Ca Cl 2 ( a q ) + H 2 O ( l ) + CO 2 ( g ) \n In this reaction , the calci um carbon ate ( Ca CO 3 ) is the base , and the hydro ch lor ic acid ( H Cl ) is the acid . The reaction produces calci um ch lor ide ( Ca Cl 2 ) as the salt , water ( H 2 O ), and carbon dio x ide ( CO 2 ) as by products . \n To observe whether this reaction is taking place , you might look for the following signs : \n 1 . E f fer ves c ence : When the calci um carbon ate react s with the hydro ch lor ic acid , it produces carbon dio x ide gas , which can cause the solution to b ubble or fo am . \n 2 . Change in p H : The reaction will lower the p H of the solution , indicating that an acid - base reaction has occurred . You can use p H paper or a p H meter to measure the p H of the solution before and after the reaction . \n 3 . Form ation of a precip itate : Cal ci um ch lor ide is a solid precip itate that can be observed sett the reaction mixture . If the reaction is complete , you should see a white or yellow ish precip itate in the solution . \n 4 . Color change : The reaction can also produce a color change in the solution , such as a yellow or orange color ation due to the formation of the calci um ch lor ide precip itate . \n 5 . In cre ase in temperature : The reaction can also produce a small increase in temperature , as the energy released during the reaction can cause the solution to heat up . \n It ' s important to note that this reaction can be dangerous , as hydro ch lor ic acid is a strong acid and can cause burn s or other inj uries if not handled properly . Always wear protect ive cl othing and eye we ar when working with ac ids , and follow proper safety protocol s when conduct ing experiments . � � � � </s>
