What situation do you use a volumetric flask, conical flask, pipette and graduated cylinder? explain your answer from the accuracy aspects of these apparatus.

When only rough approximations are needed, we use a conical flask.

When we want to measure liquid volumes to an accuracy of within about 1%, we use the graduated cylinders.  They are for also used general purpose, but not for sensitive quantitative analysis.

When extreme precise or accurate measurements are needed for dilution or preparation of liquid samples, we use the volumetric flask to contain it.

If we are preparing to perform titration, we will have to use a pipette to transfer very accurate amounts of sample. 

Product should she record in last row of the table

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
