Sarah has 100g of each element listed in the chart below, which also provides the melting point for each element. What would happen if she melted only 50g of each element? * The melting point for each element would double because the mass was changed
The melting point for each element would decrease by half because the mass was changed.
The melting process would occur more quickly, but the melting points would remain the same.
The melting process would occur more quickly, but the melting points would be decreased by half.

Which of these properties, used alone, would be least useful in identifying most minerals? a. color b. luster c. streak d. density

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.

Which element forms an ionic bond with flourine? 1) fluorine 2) carbon 3) potassium 4) oxygen
