Please help! Choose one of the chemical reactions seen in the images on the last activity
1. Explain what happens in terms of energy/ enthalpy change.
2. Is AH negative or positive?

The reaction choices are Fire, Photosynthesis,
condensation, cokking an egg, or melting ice

you can choose any one.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
