In an experiment a group gathered the following data: Mass of test tube (g) = 21.3
Mass of test tube and metal (g) = 52.7
Mass of beaker (g) = 120.40
Mass of beaker and water (g) = 137.54
Initial temperature of hot metal (°C) = 80.4
Initial temperature of cold water (°C) = 1.19
Final temperature of the mixture (°C) = 21.4
To the thousandths place, what is the specific heat of the metal used in the experiment above?

step-by-step explanation:

whole numbers, zero or greater

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.
