Answer:

Chemical Reaction

Explanation:

Copper is a transitional metal, meaning it is much more stable chemically than potassium. Potassium is considered an Alkaline Earth metal meaning it is very unstable and reacts violently. I'm not sure how in depth you have to go but this is just the surface of the explanation.

How many moles of atoms are in 6.00 g of 13C?
Lyrx [107]

Answer: 0.462 moles

Explanation: 13C indicates an isotope of carbon and its mass number is 13. It means the mass of 1 mol of 13C is 13 gram.

The question asks to calculate the number of atoms present in 6.00 grams of 13C.

To calculate the number of moles we divide the given grams by the mass of 1 mol of the element. The set could be shown easily using dimensional analysis as:

6.00gram(\frac{1mol}{13gram})

= 0.462 moles

So, there will be 0.462 moles of atoms in 6.00 grams of 13C.
