Choose the best answer below. Which of the following reactions will have the largest equilibrium constant at 298 K?
Maurinko [17]

Answer:

Explanation:

Relation between ΔG₀ and K ( equilibrium constant ) is as follows .

lnK =  -  ΔG₀ / RT

K = e^{-\frac{\triangle G_0}{RT}

The value of R and T are same for all reactions .

So higher the value of negative ΔG₀ , higher will be the value of K  .

Mg(s) + N₂0(g) → MgO(s) + N₂(g)

has the ΔG₀ value of -673 kJ which is highest negative value . So this reaction will have highest value of equilibrium constant K .

If 9.85 grams of copper metal react with 31.0 grams of silver nitrate, how many grams of copper nitrate can be formed and how ma

The balanced chemical reaction:

<span>Cu + 2AgNO3 = Cu(NO3)2 + 2Ag
</span>
We are given the amount of the reactants to be used for the reaction. These values will be the starting point of our calculations.

9.85 g Cu ( 1 mol Cu / 63.55 g Cu ) = 0.15 mol Cu
31.0 g AgNO3 ( 1 mol AgNO3 / 169.87 g AgNO3 ) = 0.18 mol AgNO3

The limiting reactant is AgNO3.

0.18 mol AgNO3 ( 1 mol Cu(NO3)2 / 2 mol AgNO3 ) (187.56 g / 1 mol) =16.88 g Cu(NO3)2

0.15 mol Cu - 0.18 mol AgNO3 ( 1 mol Cu / 2 mol AgNo3) = 0.06 mol Cu excess

<span>0.06 mol Cu ( 63.55 g Cu / 1 mol Cu ) = 3.81 g Cu excess</span>

What evidence do you see that a chemical reaction is taking place when you add hydrogen peroxide to potassium ioxide??
Yuri [45]

Answer:

Bubbling/Foaming

Heat is produced

Explanation:

A chemical reaction has occurred if

1. There is a change in colour

2. Formation of a precipitate

3. Formation of a gas

4. Change in temperature

5. Change of smell

In the reaction of hydrogen peroxide and potassium iodide, the solution quickly rises which shows the formation of gas. This means it is a chemical reaction.

The beaker/test tube/whatever you used should also become warm because it is an exothermic reaction. This means its a chemical reaction

"solid potassium iodide decomposes into iodine gas and solid potassium. Write a a balanced chemical equation for this reaction"
wel
KI (s)  ----\ \textgreater \     K(s)  + I_2 (g)

Now, balance the equation:

2KI (s)  ----\ \textgreater \     2K(s)  + I_2 (g)

I_2 in gaseous state exist as a diatomic molecule.
