Concept explainers
(a)
Interpretation:
The formula of a compound formed with hydrogen and sulfur needs to be determined.
Concept introduction:
All the elements in the periodic table can be classified as metals, non-metals and metalloids. Metals are electropositive elements which mainly form basic oxides and non-metals are electronegative elements, they mainly form acidic oxides. Non-metals are placed at the right side of the periodic table and their oxides react with water to form acidic solutions. Hydrogen is a unique element which can react with metal as well as non-metals. It forms hydride with metals and different acidic compounds with non-metals.
(b)
Interpretation:
The formula of a compound formed with hydrogen and nitrogen needs to be determined. The compound so formed must be liquid at 1 atm and 25 ∘C.

What is the osmotic pressure (in atm) of a 1.46 M aqueous solution of urea [(NH2), CO] at 3 Round your answer to 3 significant digits.arrow_forwardReagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…arrow_forward
