Answer:

The chemical equation of the reaction is given as:

2HBr(aq)+K_2S(aq)\rightarrow 2KBr(aq)+H_2S(g)

Explanation:

When aqueous solution of hydrobromic acid combines with aqueous solution of potassium sulfide they give aqueous solution of potassium bromide and hydrogen sulfide gas.

The chemical equation of the reaction is given as:

2HBr(aq)+K_2S(aq)\rightarrow 2KBr(aq)+H_2S(g)

According to reaction, 2 moles of hydrobromic acid reacts with 1 mole of potassium sulfide to form 2 moles of potassium iodide and 1 mole of hydrogen sulfide gas.

Zolol [24]

Concentration of unknown acid is 0.061 M

Given:

Concentration of NaOH = 0.125 M

Volume of NaOH = 24.68 mL

Volume of acid solution = 50.00 mL

To Find:

Concentration of the unknown acid

Solution: Concentration is the abundance of a constituent divided by the total volume of a mixture. The concentration of the solution tells you how much solute has been dissolved in the solvent

Here we will use the formula for concentration:

M1V1 = M2V2

0.125 x 24.68 = 50 x M2

M2 = 0.125 x 24.68 / 50

M2 = 0.061 M

Hence, the concentration of unknown acid is 0.061 M

Calculate the number of formula units in 1.87 mol of NH4Cl
nydimaria [60]

Answer:

1.13 x 10²⁴formula units

Explanation:

Given parameters:

Number of moles of NH₄Cl = 1.87mol

Unknown:

Number of formula units = ?

Solution:

From mole concept;

     1 mole of a substance contains 6.02 x 10²³ formula units

Now;

    1.87 moles of  NH₄Cl   1.87 x 6.02 x 10²³ = 1.13 x 10²⁴formula units
