Assume that the conductivity of a solution depends only on the total concentration of dissolved ions and that you measure the conductivity of three different solutions while performing titrations in which I.50.00 mL of 0.100 M aqueous CH3CO2H is titrated by addition of 0.100 M NaOH. II.50.00 mL of 0.100 M aqueous NaBr is titrated by addition of 0.100 M AgNO3. III.50.00 mL of 0.100 M aqueous CaCl2 is titrated by addition of 0.100 M Na2CO3. Required:
Draw its titration IIIg raphs.

Observation and experimentation have led many scientists to accept a theory about the origin of the universe. this theory is called the big bang theory. scientific evidence collected and observed by scientists around the world suggests that the universe is ever expanding from a hot and dense initial state. what makes this a scientific theory?

The human activities in two locations are described below: location a: rampant use of plastic containers location b: excessive use of pesticides and fertilizers which statement is most likely true? location a will have poor air quality because plastic is biodegradable. location a will experience water scarcity because plastic absorbs moisture. the population of honeybees will increase in location b because production of crops will increase. the population of fish in location b will decrease because the water is contaminated.
