Ava observes that a certain species of bird follows behind a herd of cattle. the bird species primarily eats insects. the birds stay
with the herd of cattle as they graze.
what is a scientific hypothesis that ava could formulate based on her observations?
a.
do the birds get any benefit from following the herd of cattle?
b.
the birds follow the herd because the cows stir up insects for the birds to eat.
c.
the birds are happier around big herds of cattle rather than small herds.
od. why does this species of bird follow herds of cattle?

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
