A study found that children with light - coloured eyes are likely to have parents with light coloured eyes.
In this study, a light-coloured eye is a dominant trait because children born from parents having light-coloured eyes also had light-coloured eyes.

Number of moles of MnO4- required to oxidise one mole of ferrous oxalate completely in acidic medium will be:-
Here is Reaction with Balance 10FeC2O4 + 6KMnO4 + 24H2SO4 ----> 3K2SO4+ 6MnSO4 + 5Fe2(SO4)3 + 24H2O + 20CO2 So we see that 6 moles of KMnO4 is required to oxidize 10 moles of FeC2O4 Then, 1 mole of FeC2O4 would be...

What are isoelectronic ions? Account for the decrease in size of following species oxide ion > Fluoride ion > sodium ion > magnesium ion.
The ions having same number of electrons are called isoelectronic ions. The above order is due to increasing order of effective nuclear charge.

Write the balanced redox reaction: a) MnO4 – (aq) + Fe2+ (aq) → Mn2+ (aq) + Fe3+ (aq)
(a) MnO4 – (aq) + 5Fe2+ (aq) + 8H+ (aq) → Mn2+ (aq) + 5Fe3+ (aq) + 4H2O(l) (b) Cr2O72– + 6Fe2+ + 14H+ → 2Cr3+ + 6Fe3+ + 7H2O.

Identify the oxidizing and reducing agents in the following equations: a) MnO4 – (aq) + 5Fe2+ (aq) + 8H+ (aq) →
Oxidizing agent = MnO4 – and Reducing agent = Fe2+ Oxidizing agent = Cr2O7 2– and Reducing agent = Fe2+ .

Eo values of MnO4-, Ce4+ and Cl2 are 1.507, 1.61 and 1.358 V respectively.
Cl2 < MnO4 _ < Ce4+
