How many moles of Na₂S will be required to completely react with 40.0 mL of 0.200 M Fe(NO₃)₃?
3 Na₂S (aq) + 2 Fe(NO₃)₃ (aq) → Fe₂S₃ (s) + 6 NaNO₃ (aq)

0.35g

Explanation:

As you can see, you'd need

0.02625

moles of potassium hydroxide in order for all the moles of iron(III) hydroxide to react. Since you have fewer moles of potassium hydroxide than you'd need, potassium hydroxide will act as a limiting reagent.

will take part in the reaction. Since iron(III) nitrate and iron(III) hydroxide are in a

1

:

1

mole ratio in the balanced chemical reaction, you can say that the reaction will produce

0.00330

moles of iron(III) hydroxide.

Use the compound's molar mass to convert this to grams

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
