9. The specific heat of copper is 0.385 J/g °C. How much thermal energy is required to increase the temperature of a 20g sample of copper from 20°C to 50°C?

Sorry  i don't understand can you rephrase that

Hiya,  (the properties of carbon depends on the structure of said element.)  although, carbon is not cohesive or adhesive.carbohydrates contain carbon, hydrogen, and oxygen.  it can bond with other carbon atoms as well as other elements.a polymer is a big ole' molecule made from smaller molecules that decided to smack together and form a covalent bond. but it is fact that carbon often forms polymers.decomposition of molecules simply means the organism is clearly dead and the molecules of said dead organism can be reutilized by living organisms.hope this !
