You eat a large meal and then hike up a hill. What kind of energy transformation is your body performing? Group of answer choices

Chemical energy to kinetic energy and gravitational potential energy

Chemical energy to kinetic energy and nuclear energy

Kinetic energy to chemical energy and light energy

Gravitational potential energy to sound energy and nuclear energy

Chemical energy to kinetic energy and gravitational potential energy

Explanation:

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

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
