As a result, the concentration of hydroxide ions remains relatively low, which contributes to its weak basicity in aqueous environments.

(a) Magnesium metal is placed into hydrobromic acid solution forming hydrogen gas and aqueous magnesium bromide.?

When magnesium metal is added to hydrobromic acid (HBr), a chemical reaction occurs, producing hydrogen gas (H₂) and aqueous magnesium bromide (MgBr₂). The magnesium displaces the hydrogen ions in the acid, resulting in the release of hydrogen gas as bubbles. The balanced chemical equation for this reaction is: Mg(s) + 2 HBr(aq) → H₂(g) + MgBr₂(aq). This reaction is exothermic and demonstrates the reactivity of magnesium with acids.

What volume (mL) of a concentrated solution of magnesium chloride (9.00 M) must be diluted to 350. mL to make a 2.75 M solution of magnesium chloride?

To find the volume of the concentrated magnesium chloride solution needed, we can use the dilution equation ( C_1V_1 = C_2V_2 ), where ( C_1 ) is the concentration of the concentrated solution, ( V_1 ) is the volume of the concentrated solution needed, ( C_2 ) is the concentration of the diluted solution, and ( V_2 ) is the volume of the diluted solution.

Plugging in the values, we get:

[ (9.00 , \text{M})(V_1) = (2.75 , \text{M})(350 , \text{mL}) ]

Solving for ( V_1 ):

[ V_1 = \frac{(2.75)(350)}{9.00} \approx 106.25 , \text{mL} ]

Therefore, approximately 106.25 mL of the concentrated solution is needed.
