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.

A chemical equation describes a chemical reaction. Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.
Answer:
E) None of the above
Explanation:
Metals react according to the activity series, thta is organized with the leats metals in in the bottom and the most reactive metals in the top. Most reactive metals displace less reactive metals in the compounds they are found.
in this series, Gold, Silver and Mercury are below Copper, this is, they are less reactive than Cu. this means none of them can displace it from its compounds.
Answer:
see below
Explanation:
The number in FRONT of the chemical moleculeor atom
2 CaCO3 2 would be the coeff....or number of moles of CaCO3
