Sodium (Na) reacts with chlorine gas (Cl2
alisha [4.7K]

Remark

The balance numbers in front of the chemicals tell you how to set up the proportion to solve your question

For every 2 moles Na only 1 mole of Cl2 is required.

Equation

2 moles Na:1 mole Cl2 :: x moles Na:4 moles Cl2

Solution

2/1 = x/4                 Cross multiply

2*4 = x*1

8 = x

Conclusion

8 moles of Na will be used. <<< Answer

The proposed mechanism for a reaction is 1. ClO-(aq) + H2O(l) =&gt; HClO(aq) + OH-(aq) SLOW 2. I-(aq) + HClO(aq) =&gt; HIO(aq) +
HACTEHA [7]

Answer:

The correct answer is option A.

Explanation:

Step 1 : Slow

ClO^-(aq) + H_2O(l)\rightarrow HClO(aq) + OH^-(aq)

Step 2: Fast

I^-(aq) + HClO(aq)\rightarrow HIO(aq) + Cl^-(aq)

Step 3: Fast

OH^-(aq) + HIO(aq)\rightarrow H_2O(l) + IO^-(aq)

When there is a recation which is taking place in a more that single steps than  the rate of the reaction is determined by the slowest step occurring in the reaction mechanism.

So, according to question step 1 is slow step which means that rate of the reaction will be :

R=k[ClO^-][H_2O]

Consider the equilibrium
Kamila [148]

Answer:

The answers are in the explanation

Explanation:

For the equilibrium:

B(aq) + H₂O(l) ⇌ HB⁺(aq) + OH⁻(aq).

By LeChatelier's principle, the increase in the concentration of a reactant (for example) at equilibrium will change the system counteracting the increasing producing more product.

Thus,

A) Will the equilibrium constant for the reaction increase, decrease, or stay the same? Why? .

The equilibrium constant is a thermodynamic constant that stay the same with the addition of a compound.

B) Will the concentration of HB⁺(aq) increase, decrease, or stay the same? Why?

By LeChatelier's principle, the addition of B will induce the formation of more HB⁺(aq) increasing the concentration.

C) Will the pH of the solution increase, decrease, or stay the same? Why?

As the addition of B induce the increasing of OH⁻, the pH of the solution will increase.

I hope it helps!
