Ammonium hydroxide ionizes as follows: NH4OH(s) NH4 +(aq) + OH-(aq). If an excess of ammonium salt, such as NH4Cl (which ionizes to give NH4 +(aq) ions) is added to the equilibrium shown above, you could predict that the result will be to....

Answers

Answer 1

Answer:

Answer: The dissociation of the base will be further suppressed.

Explanation: Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

$NH_4OH(s)\rightleftharpoons NH_4^+(aq)+OH^-(aq)$

If an excess of ammonium salt, such as $NH_4Cl$ (which ionizes to give $NH_4^+$ (aq) ions)

$NH_4Cl\rightarrow NH_4^++Cl^-$

If the concentration of $NH_4^+$ that is the product is increased, so according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease of concentration of $NH_4^+$ takes place. Therefore, the equilibrium will shift in the backward direction and the ions will start associating to form $NH_4OH$ .

Answer 2

Answer: Decrease the concentration of OH-

Suppose that geneticists developed a strain of bacteria that breaks down polyethylene, an otherwise non biodegradable plastic. How would such bacteria be useful? Do you foresee any dangers from these new bacteria?

Answers

Polyethylene is a widely used substance for manufacturing plastic. A bacteria like that could "eat" plastic garbage made from polyethelene which would be really helpful. The danger is that a bacteria can't differentiate between junk and useful things made out of PE, so they would eat everything made from it.
