Asquare boat made from iron has overall dimensions of 2.00 cm x 11.0 cm x 11.0 cm. it has a mass of 213 g. what is its density 242 g/cm3 0.880 g/cm3 51500 g/cm3 1.14 g/cm3

Density of the boat will be

Explanation: Density of a substance is calculated using the formula:

  .....(1)

Here, Dimensions of a boat is given, we can calculate the Volume using:

Volume = length × breadth × height

Dimensions are 2.00cm × 11.00cm × 11.00cm

Volume = 2cm × 11cm × 11cm =

Mass of the boat = 213 grams

Putting values in equation 1, we get

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!

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
