A 1.00 L volume of HCl reacted completely with 2.00 L of 1.50 M Ca(OH)2 according to the balanced chemical equation below. 2HCl

wolverine [178]

Answer:

$\boxed{\text{6.00 mol/L}}$

Explanation:

(a) Balanced equation

2HCl + Ca(OH)₂ ⟶ CaCl₂ + 2H₂O

(b) Moles of Ca(OH)₂

$\text{Moles of base} = \text{2.00L} \times \dfrac{\text{1.50 mol}}{\text{1 L}} = \text{3.000 mol base}$

(c) Moles of HCl

$\text{Moles of HCl} = \text{3.000 mol base} \times \dfrac{ \text{2 mol HCl}}{\text{1 mol base}} = \text{6.000 mol HCl}$

(d) Molar concentration of HCl

$\text{Molar concentration} = \dfrac{\text{moles of solute}}{\text{litres of solution}}\\\\c = \dfrac{ n }{ V}\\\\c= \dfrac{ \text{6.000 mol}}{ \text{1.000 L}} = \text{6.00 mol/L}$

The molar concentration of the HCl was $\boxed{\textbf{6.00 mol/L}}$

Which chemical equation represents a precipitation reaction? A. Mg(ClO3)2(aq) + 2HCl(aq) → MgCl2(aq) + 2HClO3(aq) B. AlBr3(aq) +

Rama09 [41]

Answer is D.

Among the given options, the products of equation A, B and C are aqueous solutions. Those are indicated by using (aq).

The balanced equation for the reaction between Li₂CO₃(aq) and FeCl₂(aq) is Li₂CO₃(aq) + FeCl₂(aq) → 2LiCl(aq) + FeCO₃(s)

LiCl is a salt while FeCO₃ is a Grey/green color precipitate. Hence, option D represents a precipitation reaction.

Which of the following is an Arrhenius acid? A) H2SO4 B) LIOH C)NH2CH3 D) CH3CH3

levacccp [35]

Answer:

Option a, $H_2SO_4$

Explanation:

According to Arrhenius concept of acids and bases, acids are those substances which releases H+ in aqueous solution and bases are those which releases OH- in aqueous solution.

Among the given only $H_2SO_4$ can release $H^+$ in aqueous solution.

$H_2SO_4 \rightarrow 2H^{+} + SO_4^{2-}$

LiOH releases $OH^-$ , therefore it is an Arrhenius base.

$NH_2CH_3$ and $CH_3CH_3$ cannot releases $H^+$ .

So, the correct option is option a.
