Answer:

4. Bi

Explanation:

The elements in Group 15 (VA)show a marked progression from nonmetallic to metallic properties with increasing atomic number.

The answer is no. 4. Bismuth (Bi)
Across the period, from left to right, metallic character decreases, meaning, when it is going down, the last element in a group will have the most metallic character. Since Bismuth (bi) is the last element, it is the most metallic. The arrangement of the group 15 elements in ascending rate of metallic character is: N (Nitrogen) P (Phosphorus), As (Arsenic), Sb (Antimony) and Bi (Bismuth). Bismuth has the lowest rate of electronegativity and ionization energy thus, it is more likely to lose an e- than the rest of the elements of the said group, which is why it is considered the most metallic.

In the laboratory you dilute 5.32 mL of a concentrated 6.00 M perchloric acid solution to a total volume of 100 mL. What is the
8_murik_8 [283]

Answer:

0.3192 M

Explanation:

From the question given above, the following data were obtained:

Volume of stock solution (V1) = 5.32 mL Molarity of stock solution (M1) = 6 M

Volume of diluted solution (V2) = 100 mL

Molarity of diluted solution (M2) =?

We can obtain the molarity of the diluted solution by using the dilution formula as shown follow:

M1V1 = M2V2

6 × 5.32 = M2 ×100

31.92 = M2 × 100

Divide both side by 100

M2 = 31.92 / 100

M2 = 0.3192 M

Therefore, the molarity of the diluted solution is 0.3192 M.

Fe(NO3)2 not sure how to get the oxidation numbers of all elements
Cloud [144]
<span>Fe(NO3)2
The NO3 part is a poly-atomic ion with total charge -1.
This is because Fe has a +2 charge and two NO3's with a -1 charge will balance out to 0.
 Most often we just make the assumption that Oxygen has a -2 oxidation number because it is very electro-negative.
So to find N, we just need an oxidation number that balances out with 3(-2) to get -1 (the total charge of the ion)</span>
