Answer:
Be³⁺
Explanation:
Be³⁺ has only one electron since it has loss 3 electron and is therefore capable of having a line spectrum similar to hydrogen atom.
Answer:
E
Explanation:
The question talks of a PHYSICAL model of the sun. An equation, chart, computer program and paragraph are most definitely not physical models.
Answer:
Empirical formula is NH₃
Explanation:
Given data:
Percentage of hydrogen = 82%
Percentage of nitrogen = 18%
Empirical formula = ?
Solution:
Number of gram atoms of H = 18 / 1.01 = 17.8
Number of gram atoms of N = 82 / 14 = 5
.9
Atomic ratio:
H : N
17.8/5.9 : 5.9/5.9
3 : 1
H : N = 3:1
Empirical formula is NH₃
Nitric oxide (NO) is the catalyst used for the oxidation of SO2 to SO3 in the lead chamber process for the manufacture of sulphuric acid.
<h3>
Nitric oxide</h3>
The volume of flask =10 liter
(a) 2SO2+O2⇌2SO3K=100
At an x a
end a/10 x/10 a/10
const KC=(x/10)(a/10)2(a/10)2=100
1001=10x⇒x=1/10
0.1 moles of O2 are present .
(b) 2SO2+O2⇌2SO3
At an x 2a
eq a/10 x/10 2a/10
contact
KC=(x/10)(a/10)2(102a)2⇒x/104=100
x=4/10=0.4 moles of O2.
