In right triangle efg, me = 25. in right triangle hjk, mh = 25. which similarity postulate or theorem proves that efg and hjk are similar?

Lithium diisopropylamide [(ch3)2ch]2nli, referred to as lda, enjoys many uses as a strong base in synthetic organic chemistry. it is customarily prepared by the reaction of diisopropylamine [(ch3)2ch]2nh with butyllithium. draw the products of the reactions in the appropriate boxes and select the acid, base, conjugate acid, and conjugate base. be sure to answer all parts.

For each of the following mixtures decide if filtering would be suitable to separate the substances. explain your answers. oil in water sugar in water sand in water chalk in water tea leaves in a cup of tea

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.
