The NaOH can react with HCl with the formula: NaOH + HCl = NaCl + H2O. So if you want to neutralize the solution, the molar number of NaOH and NCl need to be equal. So we need 0.3*50/0.1=150 milliliters.
Answer:
2000 mL
Explanation:
We have the following data:
Initial volume: V₁ = 1000 mL
Initial temperature: T₁ = -86°C + 273 = 187 K
Final temperature: T₂= 101°C + 273 = 374 K
According to Charles' law, as the temperature of a gas is increased at constant pressure, the volume is increased. That is expressed mathematically as:
V₁/T₁ = V₂/T₂
Thus, we calculate the final volume V₂ as follows:
V₂ = V₁/T₁ x T₂ = (1000 mL)/187 K x 374 K = 2000 mL
Therefore, the final volume is 2000 mL.

Explanation:
From the analysis we have in the question, we must look towards a first row transition metal ion having a d^6 configuration because it yields a paramagnetic complex having four unpaired electrons and a diamagnetic complex having no unpaired electrons.
We have two possible candidates in mind, Fe^2+ and Co^3+. However, Fe^2+ does not form as many coloured complexes as stated in the question so we have to eliminate that option.
We are now left with only Co^3+. Various ligands are going to cause these various colours of Co^3+ to appear in solution.
Hence, we can deduce from all these that the nature of ligands determines the colour of the complex . Don't forget that the colour of a complex arises from crystal field splitting.
