Answer:
Pb(NO3)2+2NaCl \to PbCl2+NaNO3
Explanation:
Lead(II) nitrate is
Sodium Chloride is
This is a double displacement reaction. Hence anions or cations of both the compounds are displaced to form the products.
Therefore the balanced equation is
I think energy is released
The conversion factor to use in this case is:
charge / mass = 5.4 x 10^6 z / w
We are given that:
charge = 4.5 x 10^−15 z
Therefore the mass is calculated by combining the two
equations:
4.5 x 10^−15 z / mass = 5.4 x 10^6 z / w
<span>mass = 8.33 x 10^-22 w</span>
Perchloric acid (HCO₄) is one of strongest inorganic acids. Perchloric acid precipitation is used to removes most of the protein present in the
sample and stabilize many of the small molecule analytes. It can use also to precipitation glycogen, ATP, glutathione, antioxidants.
Perchloric acid donates protons to macromolecules and lower their solubility in water. Also perchloric acid is strong oxidizing agent and change oxidation number of elements.
