What mass of HCl is neutralized by 3.33 g Mg(OH)2?
postnew [5]
First, you write the balanced equation for the reaction

2HCl + Mg(OH)2 ----->MgCl2 + 2H2O


Next, find the number of moles of Magnesium Hydroxide

Number of moles of Mg(OH)2 =

mass / Mr = 3.33 / 24 +2(1+16)
=0.0574 mol

Find the mole ratio between HCl and Mg(OH)2 which is 1:2

Number of moles of HCl = 0.0574 x 2 = 0.1148 mol

Mass of HCl = Mr x no. of moles
=0.1148 x (1+35.5)
=4.19 g

Calcium hydroxide is partially soluble as shown by the
Blizzard [7]

Answer:

4

10

Explanation:

The reaction equation is given as;

            Ca(OH)₂     →    Ca²⁺   + 2OH⁻

Concentration of Ca(OH)₂ = 5 x 10⁻⁵M

         

Unknown:

pOH of the solution  = ?

pH of the solution = ?

Solution:

Solve for the pOH of this solution using the expression below obtained from the ionic product of water;

                 pOH  = ⁻log₁₀[OH⁻]

           Ca(OH)₂             →           Ca²⁺              +              2OH⁻

          1moldm⁻³                         1moldm⁻³                     2 x 1moldm⁻³

         5 x 10⁻⁵moldm⁻³         5 x 10⁻⁵moldm⁻³            2( 5 x 10⁻⁵moldm⁻³ )

                                                                                            1 x 10⁻⁴moldm⁻³

  Therefore;

             pOH = -log₁₀ 1 x 10⁻⁴ = 4

Since

           pOH + pH  = 14

                        pH  = 14  - 4  = 10

What is the mole ratio of D to A in the generic chemical reaction? 2A+B &gt;C+3D
Anit [1.1K]

Answer: The mole ratio of D : A is 3 : 2.

Explanation: Mole ratio for a chemical reaction is the ratio of their respective stoichiometric numbers or the ratio of their moles in a chemical reaction.

For a given chemical reaction:

2A+B\rightarrow C+3D

By stoichiometry,

2 moles of A is reacting with 1 mole of B to produce 1 mole of C and 3 moles of D.

So, Mole ratio of D is to A will be 3 : 2
