Answer:

g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.

Explanation:

Sulfuric acid is represented as H₂SO₄ and calcium hydroxide is represented as Ca(OH)₂.

  • To balance a chemical reaction. we should apply the law of conservation of mass that the no. of different atoms in both sides (reactants and products).

  • The only choice that represent the reactants correctly and apply the law of conversation of mass is:

<em>g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.</em>

<em></em>

<em>f. H₂SO₄ + 2Ca(OH)₂ → 2CaSO₄ + 3H₂O </em>

is not correct that the no. of S, and O is not equal in both reaction sides.

S in reactants (1) while in products (2).

<em>O in reactants (8) while in products (11).</em>

<em></em>

<em>h. HSO₄ + CaOH → CaSO₄ + H₂O</em>

The reactants is represented in a wrong way.

<em> j. H₂SO₄+ Ca(OH)₂ → CaSO₄ + H₂O</em>

is not correct that the no. of H and O is not equal in both reaction sides.

H in reactants (4) while in products (2).

O in reactants (6) while in products (5).

<em></em>

<em>So, the right choice is: g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.</em>

A solution contains one or more of the following ions: Ag , Ca2 , and Co2 . Lithium bromide is added to the solution and no prec
koban [17]

Answer:

Ca^{2+}  and  Co^{2+}

Explanation:

Given:

A solution contains one or more of the following ions such as Ag, Ca_2 and Co_2

Here the Lithium bromide is added to the solution and no precipitate forms

Solution:

Since with LiBr no precipitation takes place therefore Ag+ is absent

Here on adding Li_2SO_4 to it precipitation takes place.

Precipitate is as follows,

Ca^{2+}(aq)+SO_4^2^-(aq)----->CASO_4(s)

Thus,

Ca^2^+ is present

When Li_3PO_4 is added again precipitation takes place.

Therefore the reaction is as follows,

Co^2^+(aq)+PO_4^3^-(aq)------>Co_3(PO_4)_2(s)

Therefore,

Ca^{2+}  and  Co^{2+} are present in the solution

What is the maximum mass of aluminum chloride that could be obtained from 6 mol of barium chloride?
kodGreya [7K]
You have to find the stoichiometric ratio between AlCl₃ and BaCl₂. The common element between them is Cl. So, the ratio of Cl in BaCl₂ to AlCl₃ is 2/3. The molar mass of AlCl₃ is 133.34 g/mol. The solution is as follows:

Mass of AlCl₃ = (6 mol BaCl₂)(2 mol Cl/1 mol BaCl₂)(1 mol AlCl₃/3 mol Cl)(133.34 g/mol) = 533.36 g AlCl₃
