Answer:The outer core of the Earth contains a lot of iron in a molten state. As the Earth spins this molten iron moves and creates the Earth's magnetic field. The Earth behaves as if there is a huge bar magnet at its centre. The shape of the field around the Earth is very similar to the field around a bar magnet
Explanation:
6.0 will the pH at the neutralization point of 0.00812 m Ba(OH)2 be when titrated with HCl.
<h3><u>What are </u><u>
titration reactions ?</u></h3>
A titrant/titrator, a standard solution with fixed volume and concentration, is prepared as part of the titration procedure. When an endpoint or equivalence point is reached, the titrant is made to continue reacting with the analyte, and at that point, the amount of titrant consumed may be used to calculate the analyte's concentration. Alternately, titration is the application of the stoichiometry principle to determine an unknown solution's concentration.
The technique begins by adding a very little quantity of analyte to a beaker or Erlenmeyer flask. Under a calibrated burette or chemical pipetting syringe containing the titrant, a little quantity of an indicator (such as phenolphthalein) is inserted.

Answer:
Oxidation Number of Phosphorous = + 6
Explanation:
According to Rules of Assigning Oxidation States;
i) The Oxidation State of Hydrogen atom in a compound is assigned as +1 except for Hydrides i.e. NaH and MgH₂ where it is assigned with -1.
ii) The Oxidation State of Oxygen in a compound is assigned as -2 except for Peroxides where it is given -1 and OF₂ where it is assigned with +1 respectively.
Oxidation State of P in H₂P₃O₁₀;
As over all molecule is neutral we can write it as,
H₂P₃O₁₀ = 0
Putting oxidation number of H and O,
(+1)₂ + P₃ + (-2)₁₀ = 0
(+2) + P₃ + (-20) = 0
+ 2 + (P)3 -20 = 0
(P)3 = + 20 - 2
(P)3 = + 18
P = + 18 ÷ 3
P = + 6
