How many liters of 0.305 M K3PO4 solution are necessary to completely react with 187 mL of 0.0184 M NiCl2 according to the balan

Mashutka [201]

Answer:

6.55 mL of K₃PO₄ are required

Explanation:

We need to propose the reaction, in order to begin:

2K₃PO₄ (aq) + 3NiCl₂(aq) → Ni₃(PO₄)₂ (s) ↓ + 6KCl (aq)

Molarity = mol/L (Moles of solute that are contained in 1 L of solution.)

M = mol / volume(L). Let's find out the moles of chloride:

- We first convert the volume from mL to L → 187 mL . 1L / 1000mL = 0.187L

0.0184 M . 0.187L = 0.00344 moles of NiCl₂

Ratio is 3:2. Let's propose this rule of three:

3 moles of chloride react with 2 moles of phosphate

Then, 0.00344 moles of NiCl₂ will react with (0.00344 . 2) /3 = 0.00229 moles of K₃PO₄

M = mol / volume(L) → Volume(L) = mol/M

Volume(L) = 0.00229 mol / 0.350 M = 6.55×10⁻³L

We convert the volume from L to mL → 6.55×10⁻³L . 1000mL /1L = 6.55 mL

H2(g) + CO2(g) + 10 kcal H2O(g) + CO(g)

EleoNora [17]

<u>Answer:</u> The equilibrium constant for the given reaction is 0.8

<u>Explanation:</u>

Equilibrium constant is defined as the ratio of concentration of the products raised to the power its stoichiometric coefficients to the concentration of reactants raised to power its stoichiometric coefficient. It is represented as $K_c$

For the general equation:

$aA+bB\rightleftharpoons cC+dD$

The equilibrium constant is represented as:

$K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}$

For the given chemical equation:

$H_2(g)+CO_2(g)+10 kcal\rightleftharpoons H_2O(g)+CO(g)$

$K_c$ for this equation is given by:

$K_c=\frac{[H_2O][CO]}{[H_2][CO_2]}$

Concentration at equilibrium of

$H_2=2mol/L\\H_2O=4mol/L\\CO_2=5mol/L\\CO=4mol/L$

Putting values in above equation, we get:

$K_c=\frac{4\times 4}{2\times 5}\\K_c=0.8$

Hence, the equilibrium constant for the given chemical reaction is 0.8
