Which of the following is the correct set up AND answer to convert 6.25 x
BlackZzzverrR [31]

Answer:

Explanation:

How many mols do you have?

1 mol = 6.02 * 10^23 atoms

x mol = 6.25 * 10 ^32 atoms

1/x = 6.02*10^23 / 6.25 * 10^32        Cross multiply

6.02 * 10^23 * x = 1 * 6.25 * 10^32    Divide by 6.02 * 10^23

x = 6.25 * 10*32/ 6.02 ^10^23

x = 1.038 * 10^9 mols which is quite large.

Find the number of grams. (Use the value for copper on your periodic table. I will just use an approximate number.)\

1 mol of copper = 63 grams.

1.038 * 10^9 mols of copper = x

1/1.038 * 10^9 = 63/x         Cross multiply

x = 1.038 * 10^9 * 63

x = 6.54 * 10^10 grams of copper.

How does fluorine electronegativity compare to the electronegativity of oxygen and chloride?
Artemon [7]

Answer:

Cl EN < O EN < F EN

Explanation:

Electronegativity is a periodic property that indicates the tendency of an atom to attract electrons when combined with another element. It is very useful for predicting the type of bonding of compounds, so it is not possible to talk about electronegativity in elements in a fundamental state.

In the periodic table the electronegativity increases diagonally and the values ​​were established in the so-called Pauling scale.  

It is expected that elements with high electron affinity and high ionization energy possess considered electronegativity, so the group of nonmetals have high electronegativity, in fact flour is the most electronegative element
