Write a word or phrase beginning with each letter of the word gold that described the properties of these gold coins plzz

The properties of GOLD is given below.

Explanation:

Gold is the 79th element of the periodic table. It is considered as a transition element because it belongs to d-block of the periodic table.

The properties of Gold from each letter of the word is:

G : As, it is a metal it will be a good conductor of electricity and heat.

Hence, G stands for good conductor of heat and electricity.

O : It is a solid and thus will be opaque in nature.

Hence, O stands for Opaque.

L : As, it is a metal it will show a lustrous property.

Hence, L stands for lustrous.

D : As, it is a metal, it will show the property of ductility which means that it can be drawn into wires.

Hence, D stands for ductile.

Thus, the properties for GOLD from each letter is given above.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

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!

if you need further assistance, let me know: )
