The answer is: first substance is base and second is acid.
Bases, for example solution of sodium hydroxide (NaOH) feels slipery.
Sodium hydroxide dissociation in water: NaOH(aq) → Na⁺(aq) + OH⁻(aq).
Ionic compounds are good good electricity and heat conductors, because ionic compounds have mobile ions (cations and anions) that are able to transfer electrical charge.
In second reaction, magnesium is oxidized from oxidation number 0 to +2 and hydrogen is reduced from +1 to 0 (hydrogen gas).
Answer:
0.508 L of solution.
Explanation:
Always a safe bet to convert to moles:
Where n is moles, m is mass, and MM is molar mass.
Now remember the equation for concentration (molarity):
Where C is the concentration, n is moles, and V is volume.
To make this easy, combine the two equations (note n appears in both, so you can do a substitution) and solve for V as the question asks:
Therefore we can make 0.508 L of solution.
