Answer:
Hence the concentration of a MnO41- solution that has absorbance of 0.490 in the same cell at that wavelength is 0.3266.
Explanation:
Now A = el, el=const
Then,
Explanation:
1. Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
2. Charles' Law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles
3. Gay Lussac's Law states that tempertaure is directly proportional to the pressure of the gas at constant volume and number of moles of gas
(At constant volume and number of moles)
Answer:
The pH of the solution could 10

The ion or molecule that forms the bond with the transition metal is called a ligand, e.g. :Cl-, :CN-, H2O:, :NH3. More than one ligand can bind to a transition metal ion to form a complex ion. The copper ion, Cu2+ (aq), in aqueous solution, forms a blue complex ion, [Cu(OH2)6]2+, with 6 water molecules.
Answer:
Number of grams of mineral salt in one liter of water
.
Explanation:
Salinity :
It is the concentration of dissolved salts .
Salinity means the saltiness or the dissolved salt component in the water body . It is defined as mass (in gram) of the dissolved matter in the water bodies .
salts found in ocean water are :
Salts of chlorides, sulfates , sodium , magnesium, potassium and calcium
For example : world's oceans salinity is 3.5% parts per thousand (g/L) . It means 3.5 g of salt is present in 1 L of seawater .
Note : Sodium chloride is major salt found in ocean . But it is not the only salt present (other salts are also found) . So D can't be the answer
