Metals are good conductors of heat and electricity
Metals are good conductors due to presence of free electrons
They act as carrier to conduct heat or electricity.
So
Aluminum spoon will heat up as it is of metal
Iron spoon will heat up as it is of metal
Silver spoon will also heat up as it is of metal
Wood is a bad conductor of heat. It is an insulator
Wood has air space or pockets in its structure which makes it a bad conductor (it cannot conduct heat)
So a wooden spoon will be stay coolest as it is an insulator
Explanation:
12.0 mol KClO3 × (3 mol O2/2 mol KClO3)
= 18.0 mol O2
Well, even though it may look like the last option is the correct one, that one is wrong. When a crystal s formed from many metals there are many milecular orbitals. So the answer is B. Hope this is what you are looking for
SiO2 is the chemical formula silicon and oxygen
For this question, you must know that there are 6.022e23 atoms/molecules per mole of any substance (this is Avogadro's number). Therefore, your answer is 6.022e23 * 1.60 = 9.64e23 molecules of sulfur dioxide. (the "e" represents "times ten to the power of ___ ")
