Answer:
6.63*10-7 m
Explanation:
The energy of one mole of the compound is obtained by dividing by the Avogadro number. Then the wavelength is obtained from
E= hc/wavelength as shown in the question.
Answer:
5.The limiting reactant is completely used up in the reaction
Explanation:
The limiting reactant is completely used up in the reaction is the correct answer because a limiting reactant is a reactant in chemical reaction that is completely consumed or used up in the chemical reaction. Limiting reactant when it is completely used up limits the amount of products that will be formed. The reaction will be halted or will stop when the limiting reactant is totally used up.
An atom has an average atomic mass of about 63.5 amu.
<span>
1 amu is equal to 1 gram per mole
so 63.5 amu is just equal to 63.5 grams per mole or 63.5 g/mol
the answer is Cu or copper.

The answer above is correct (I took a test on this)
