Answer:1.2g of NaOH

Explanation:

First we put down the equation of reaction as shown in the image attached. From the equation of reaction, we can calculate the mass of sodium hydroxide that reacts with one mole of iron II ion according to the balanced stoichiometric equation. Using the information provided about the iron II nitrate, we can calculate the amount of Fe2+ that reacted with sodium hydroxide as shown in the image. Lastly, we use this information to obtain the mass of sodium hydroxide that reacted with the stipulated amount of NaOH.

Can pressure affect the solubility of a substance in solution ? Explain
Tema [17]

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
