An amount of lactic acid is dissolved in water and the reaction is allowed to reach equilibrium. The concentration of the protonated acid is found to be 2.5 M.
When X-rays with ? = 1.937 Å are used, the second-order Bragg reflection from a set of parallel planes in a(n) cesium crystal is observed at an angle
An oxide of copper is decomposed forming copper metal and oxygen gas. A 0.500 g sample of this oxide is decomposed, forming 0.444 g of copper metal. What is the empirical formula of the copper oxide?
NaF > MgF2 due to the lower molar mass of NaF. d) Si > SiF4 due to covalent-network bonding in Si, versus dispersion forces in SiF4. e) SiO2 > SeO2 due ionic bonding in SiO2 but not in SeO2.
