Answer:
1. conduction happens
2. gold silver iron, ect
3. they are good conductors for electricity and heat
4. atoms who have tightly bound electrons
5. plastic, paper, rubber, glass
6. radiant barriers
Explanation:
Iron (II) oxide is composed of iron with an oxidation number of +2 (shown by the II after iron) and an oxygen that has an oxidation number of -2 (oxygen almost always has an oxidation state of -2). Since the anion and cation both have a charge of +or- 2, they bond with each other with a 1 to 1 ratio and the formula should be FeO
I hope this helps. Let me know if anything is unclear.
EF5 tornado will do more damage than a EF10 tornado because EF10 tornado doesn't even exist.
Answer:
Therefore the coins were of yellow brass.
Explanation:
A sample weighted 129.6 g and had a volume of 15.3 cm³.
Here mass= 129.6 g and volume =15.3 cm³.
g/cm³
=8.47 g/cm³
Given that the density of gold = 19.3 g/cm³
and density of yellow brass = 8.47 g/cm³
Since the density of the sample is equal to the density of yellow brass.
Therefore the coins were of yellow brass.
Number of moles of the gas, Temperature and the volume of the gas.
