esc Sort the molecular compounds in the table into groups with the same empirical chemical formula. . That is, select Group 1 next to all the compounds with the first empirical formula. (If all four compounds have the same empirical formula, then they'll all end up in Group 1.) • Next, select Group 2 next to all the compounds with the second empirical formula. And so on. • If all four compounds have different empirical formulas, then they'll each end up alone in their own group: Compound A will be alone in Group 1, Compound B will be alone in Group 2, and so on. About the sketches: the lines stand for chemical bonds between the atoms. Just ignore the dots. They stand for "lone pairs," and you'll learn about them later. You don't need to know anything about lone pairs to solve this problem. compound A B Explanation F2 Check sketch of molecules in it H (@ HEL 2 H H-Ö- 3 C H :O: H H || | | H-Ö C-C-C-C-H 80 F3 HI H HIC- O: $ 0=0 4 -I H H H H F4 I-C H C-Ö H % 5 F5 Group 2 group (Choose one)…

A) Chlorophyll molecules are responsible for the green pigmentation of plants. Differing chemically isolated molecular chlorophyll compounds are named as "Chlorophyll X" (where "X" is a variable denoting the actual molecular fragments which are represented by the labels R2, R3, R7, R8, R17). Suppose one molecule of Chlorophyll X contains 4 nitrogen atoms, and Chlorophyll X is 6.26 % nitrogen by weight. Using only this information and the atomic mass of nitrogen, determine the molecular mass of Chlorophyll X. B) The Chlorophyll X molecule contains one magnesium atom. What mass of magnesium is found in 5.17 g of Chlorophyll X compound?

Consider these compounds: A. Al(OH)3 B. Ag3PO4 C. Zn3(PO4)2 D. Ca3(PO4)2 Complete the following statements by entering the letter(s) corresponding to the correct compound(s). (If more than one compound fits the description, include all the relevant compounds by writing your answer as a string of characters without punctuation, e.g, ABC.) Without doing any calculations it is possible to determine that barium phosphate is more soluble than , and barium phosphate is less soluble than . It is not possible to determine whether barium phosphate is more or less soluble than by simply comparing Ksp values.
