4. A. What is the percent by mass of water present in CoCl2.6H20? B. Name the hydrate.

1 answer:

8 0

52.17%

using periodic table.. We get the molar mass respectively for C, O, Cl and H20 . You get an answer as 207 by adding all of them . Then as we have 6 water molecules and we get 108 . so we have to divide 108 and 207 then multiply the decimal with 100 . we get 52.17%

a sample of ammonia contains 9g hydrogen and 42g nitrogen. another sample contains 5g hydrogen .calculate the amount of nitrogen

balandron [24]

9 g of hydrogen - 42 g of nitrogen
5 g of hydrogen - x g of nitrogen

$9x=42 \cdot 5 \\
9x=210 \\
x \approx 23.33$

The mass of nitrogen in the second sample is 23.33 g.

Which of these elements has an atom with the most stable outer electron configuration? * Cl Ca Ne Na

SashulF [63]

Answer:

Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure

Explanation:

The configuration of these elements is as follows;

Cl₁₇ = 2, 8,7 (the outer electron is 7)

Ca₂₀ = 2,8,8,2 (the outer electron is 2)

Ne₁₀ = 2,8 (the outer electron is 8)

Na₁₁ = 2,8,1 (the outer electron is 1)

Based on the outer electron value above, Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure.
