Answer:
electronegativity increases
Greetings!
<h3>To find the empirical formula you need the relative atomic mass of each element!</h3>
N = 14
H = 1
S = 32.1
<h3>You can simply change the percentages into full grams</h3>
N = 12.20
H = 6.06
S = 48.45
<h3>Then you use this to find the Number of moles = amount in grams / atomic mass</h3>
N = 12.20 ÷ 14 = 0.8714
H = 6.06 ÷ 1 = 6.06
S = 48.45 ÷ 32.1 = 1.541
<h3>Then divide each number of moles by the smallest value:</h3>
N = 0.8714 ÷ 0.8714 = 1
H = 6.06 ÷ 0.8714 = 6.9 ≈ 7
S = 1.541 ÷ 0.8714 = 1.76 ≈ 2
So that means that there are 1 Nitrogen, 7 hydrogen, and 2 sulfur. This means the empirical formula would be:
NH₇S₂
Hope this helps!

Answer:
104.1 mL
Explanation:
c1V1 = c2V2
V1 = c2V2/c1 = (0.333 M×2500 mL)/8.00 M
V1 = 104.1 mL
