The table compares the type of reactants and products taking part in two chemical changes.

chemical change comparison

chemical reaction reactants products

x an element and a compound a compound

y an element and another element a compound

which of the following statements correctly identifies the synthesis reaction and explains why?

only chemical reaction x, because one reactant is a compound

only chemical reaction y, because both reactants are elements

neither chemical reaction x nor y, because they have only one product

both chemical reactions x and y, because there are two reactants and a single product

Iwill give extra points to who gets this right

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.

The boiling point of liquids is very high what does it indicate
