Answer:

Keq = [H₂]⁴[CSe₂]/[CH₄][H₂Se]².

Explanation:

  • The equilibrium constant expression is the ratio of the concentrations of the products over the reactants.

  • For the reaction:

<em>CH₄(g) + 2H₂Se(g) ⇄ 4H₂(g) + CSe₂(g).</em>

<em></em>

<em>∴ Keq = [products]/[reactants] = [H₂]⁴[CSe₂]/[CH₄][H₂Se]².</em>

At 25 °C, an aqueous solution has an equilibrium concentration of 0.00253 M for a generic cation, A2+(aq), and 0.00506 M for a g
aleksandrvk [35]

Answer:

The equilibrium constant Ksp of the generic salt AB2 =  6.4777 *10^-8 M

Explanation:

Step 1: The balanced equation

AB2 ⇒ A2+ + 2B-

Step 2: Given data

Concentration of A2+ = 0.00253 M

Concentration of B- = 0.00506 M

Step 3: Calculate the equilibrium constant

Equilibrium constant Ksp of [AB2] = [A2+][B-]²

Ksp = 0.00253 * 0.00506² = 6.4777 *10^-8 M

The equilibrium constant Ksp of the generic salt AB2 =  6.4777 *10^-8 M

The burning of 1.0 g of coal produces 8.4 kcal. How many kilojoules are produced?
Andre45 [30]
The conversations need to solve this problem:

1 cal = 4.184 joules
1 Kcal= 1000 calories
1 kj= 1000 joules

or a more direct approach---->> 1 Kcal = 4.184 Kjoules

8.4 kcal (1000 calories/ 1 Kcal) x (4.184 joules/ 1 cal) x (1 Kj/ 1000 joules)= 35.1 Kj

or 8.4 kcal (4.184 Kj/ 1 kcal)= 35.1 Kj (same answer)
