We say that the solution is unsaturated.

Explanation:

If the salt solubility is 36 g in 0.1 L of water then we can dissolve 360 g of salt in 1 L of water.

Because the solution contains 200 g of salt in 1 L of water, the solution is unsaturated because more salt can be added until we reach the saturation point.

We call the solution dilute when we compare the concentration of a solution with the concentration of another solution, but here we do not compare different solutions.

.A volumetric pipette is used to measure 25.0cm3 of 2.0mol/dm3 aqueous sodium hydroxide into aconical flask.A burette is filled

Mila [183]

Answer:

A volumetric pipette is used to measure 25.0cm3 of 2.0mol/dm3 aqueous sodium hydroxide into aconical flask.

A burette is filled with dilute sulfuric acid.

Write a balanced symbol equation for the reaction between these chemicals when we neutralise.

Explanation:

The reactants of the given reaction are:

sodium hydroxide and dilute sulfuric acid.

The balanced chemical equation of the reaction is:

$H_{2}SO_{4} (aq) + 2NaOH(aq) -> Na_{2} SO_{4} (aq)+ 2H_{2} O(l)$

Acid and base raect with each other and form salt and water.

This reaction is called a neutralization reaction.

2. Calculate how many moles of H2 would be produced if 0.250 mol of Fe reacts completely. (1 mark)

den301095 [7]

Hey there!:

Balanced Equation , for the reaction:

3 H₂SO₄(aq) + 2 Fe(s) → Fe₂(SO₄)₃(aq) + 3 H₂(g)

2 moles Fe ---------------------------------- 3 moles H₂

0.250 moles Fe ---------------------------- ( moles H₂ ) ??

____________________________________________

moles H₂ = 0.250 × 3 / 2

moles H₂ = 0.75 / 2

moles = 0.375 moles of H₂

Hope this helps!
