Answer : 0.25 M
explanation :
- Molarity is the number of moles of solute per liters of solvent.
- Molarity (M) = (n) / V (liter) = 2 / 8 = 0.25 M
The answer is 600N because if its 600 and 0 its still going to be 600
So ions are atoms that have either gained or lost electrons to complete their energy levels.
In order for a positive ion to be formed, an atom must lose electrons.
In order for a negative ion to be formed, an atom must gain electrons.
When an atom loses and electron, it loses a negative charge and then becomes a positive ion.
K = 0.058 yr (constant)
Fraction of the pesticide = 36 years/12 = 3 half-lives , so around 1/8 left
when 99.9 % decomposed, 0.1 % is left , so the fraction is 0.001. To reach this point, it will take around +/- 120 years
For example couple Cu/Zn.
The electronegativity of zincum is less, than at copper.
(Cu, cathode, -) 2H₂O + 2e⁻ → H₂ + 2OH⁻
(Zn, anode, +) Zn → Zn²⁺ + 2e⁻
