The name of an ionic hydride and a covalent hydride is to be given, preparation for each case is to be described, and the structure of the compound is to be given. Concept Introduction: The hydrogen bond involves interaction between partial positive-charged hydrogen atoms and more electronegative atoms. The electronegative atoms could be nitrogen, oxygen, fluorine, and adjacent atoms that contain a lone pair of electrons. All those compounds that contain an element linked to hydrogen atom, in which hydrogen is considered a more electronegative species, are known as binary hydrides. It could be ionic, covalent, or interstitial. Ionic hydrides are the hydrides in which a hydrogen atom is linked directly with an alkali metal. Covalent hydrides are the hydridesin which a hydrogen atom is bonded to the atom of another element covalently. Interstitial hydrides are the hydridesin which a hydrogen atom and a metal are found in constant ratio, which means hydrogen atom is combined to the metal.

What is the average mass of the 10 pennies? Report your value with correct significant figures. What is the error (uncertainty) associated with each mass measurement due to the equipment? What is the uncertainty associated with the average value? Note that the uncertainty of the balance will propagate throughout the calculation. What is the standard deviation of the 10 mass measurements? Explain the difference between the propagated uncertainty and the standard deviation. Which number would you use to describe the uncertainty in the measurement? Calculate the total mass of the pennies with associated uncertainty. Calculate the average density of a penny based on these data. Propagate the uncertainty values for both mass and volume in your calculations.
