Green colored precipitate of iron (||) hydroxide
0.023, to do it, just simply divide the energy value by 1000.
Tantalum is the 73rd element in the periodic table with an atomic mass equal to 180.95 g/mol. To determine the number of moles present in the given mass of tantalum above, we simply divide the mass by the atomic mass.
number of moles = (0.0073 kg)(1000 g/ 1kg) ÷ (180.95 g/mol)
number of moles = 0.0403 moles
Therefore, there is approximately 0.0403 moles of tantalum in 0.0073 kg.
The correct option is DISSOCIATE.
Acids ionize in water producing hydrogen ions while bases dissociates in solutions. Strong acids ionize completely in water while weak acids only ionize partially. Strong bases dissociate completely in solution while weak bases are typically undergo partial dissociation.
