Consider the following chemical reaction :
aFe2O3(s) + bCO(g) + cFe(s) + dCO2
In the balanced chemical equation of the above, which of the following will be the values of the coefficients a, b, c and d respectively?
Fe2O3 + 3CO = 2Fe + 3CO2
Hematite + Carbon Monoxide = Iron + Carbon Dioxide
In this reaction, the iron oxide is reduced to iron, and the carbon is oxidised to carbon dioxide.

Which category of Hydrogen releases water vapour and a by product when burnt?
Which among the following noble gas has highest molar mass?
Match List -I with List -II and select the correct answer using the code given below the Lists :
List -I List-II
(Compound/Molecule) (Shape of Molecule)
A. CH3F 1. Trigonal planar
B. HCHO 2. Tetrahedral
C. HCN 3. Trigonal pyramidal
D. NH3 4. Linear
HCHO: The carbon and and the oxygen are bonded through a double bond which counts as "one electron pair". Hence the molecule has three electron pairs and is trigonal planar.
