Alternative fuel sources such as solar and wind energy are gaining popularity and replacing fossil fuels in many applications. While there are many positive benefits to this technology, what negative impacts do they present?

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

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
