2) Decrease temperature

3) Increase concentration of reactants

4) Increase pressure

5) Decrease pressure

Explanation:

Le Chatelier's Principle Fundamentals states that a chemical reaction at equilibrium that undergoes changes to pressure, temperature, or concentration, this will cause the equilibrium to shift in the opposite direction to offset the change.

Please and thank you!
Valentin [98]

Answer:

7.5 moles of O₂.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2KClO₃ —> 2KCl + 3O₂

From the balanced equation above,

2 moles of KClO₃ decomposed to produce 3 moles of O₂.

Finally, we shall determine the number of mole of O₂ produced by the decomposition of 5 moles of KClO₃. This can be obtained as follow:

From the balanced equation above,

2 moles of KClO₃ decomposed to produce 3 moles of O₂.

Therefore, 5 moles of KClO₃ will decompose to produce = (5 × 3)/ 2 = 7.5 moles of O₂.

Thus, 7.5 moles of O₂ were obtained from the reaction.

<h2>Answer:</h2>

A.NH4Cl

<h2>Explanations:</h2><h2>How are buffer formed?</h2>

Buffers are formed by mixing an equal amount of weak base or acids and their corresponding salts.

Therefore in order to make a buffer with NH3 (a weak base), then a corresposding weak salt is required. A corresponding salt for the given base is NH4Cl
