If the heat of combustion for a specific compound is − 1160.0 kJ / mol and its molar mass is 74.23 g / mol, how many grams of this compound must you burn to release 264.90 kJ of heat?

16.95 grams of this compound must be burn to release 264.90 kJ of heat.

Explanation:

The heat of combustion of a compound =

Suppose n moles of compound on combustion gives Q amount of energy

Q = -264.90 kJ

Mass of 0.2284 moles of compound = m

Molar mass of compound = M = 74.23 g/mol

16.95 grams of this compound must be burn to release 264.90 kJ of heat.

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.
