Document Summary
Elemental analysis shows that 14. 35g of tale contains 7. 264g of oxygen. Which of the following is the molecular formula of tale: mg3si4o10(oh)2, ca3si4o10(oh)2, na6si4o10(oh)2, k6si4o10(oh)2, upon addition of 4. 93g calcium hydroxide to 0. 500l of a 0. 0680m aqueous solution of h3po4, solid ca3(po4)2 and water form. What is the theoretical yield of calcium phosphate in this reaction: 10. 5g, 5. 27g, 20. 6g, 26. 8g, 7. 41g, a hydrogen atom in its ground state absorbs ultraviolet radiation having a frequency of. What is the principal quantum number of the electron in the atom"s final state: n=3, n=4, n=5, n=7, n=9, which element possesses all of the following characteristics. The ground-state electron configuration of its atoms has two unpaired electrons; It has density of 12. 4g cm-3 and adopts a face-centred cubic unit cell. Lino3 solution: the na2o solution will have a lower osmotic pressure and higher vapor pressure than the lino3 solution, the na2o solution will have a lower osmotic pressure and higher boiling point than the.
