Ensure Safety in the Laboratory A base with a light bulb and two long prongs sits above a beaker partially filled with liquid; the prongs extend into the liquid. To the right, 2 wires extend from a source labeled Power; 1 attaches to the base and 1 to the right-hand prong. On the left, 2 wires are attached to the terminals of a battery, with 1 wire attached to the base and 1 to the left-hand prong. In a conductivity apparatus, like the one above, you should never touch the while the power is on.

11 players on a field that has a maximum of 11 players

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
