A chemist heated a 88.3 g sample of a metal to 122.6°C, then put the sample into a calorimeter with 100 mL of water that was at 22.5°C. The temperature of the system stabilized at 31.7°C. What is the
heat capacity of the metal? The heat capacity of water is 4.18 J/g °C. Show all of your work for full

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
