To determine the concentration of a sample of calcium hydroxide, 1.45M HCl is added drop-wise using a burst. Write the balanced
GenaCL600 [577]

Answer:

H^+(aq) + OH^-(aq) —> H2O(l)

Explanation:

We'll begin by writing the balanced equation for the reaction.

2HCl(aq) + Ca(OH)2(aq) —> CaCl2(aq) + 2H2O(l)

Ca(OH)2 is a strong base and will dissociates as follow:

Ca(OH)2(aq) —> Ca^2+(aq) + 2OH^-(aq)

HCl is a strong acid and will dissociates as follow:

HCl(aq) —> H^+(aq) + Cl^-(aq)

Thus, In solution a double displacement reaction occurs as shown below:

2H^+(aq) + 2Cl^-(aq) + Ca^2+(aq) + 2OH^-(aq) —> Ca^2+(aq) + 2Cl^-(aq) + 2H2O(l)

To get the net ionic equation, cancel out Ca^2+ and 2Cl^-

2H^+(aq) + 2OH^-(aq) —> 2H2O(l)

H^+(aq) + OH^-(aq) —> H2O(l)

Given the balanced equation:
Vikki [24]

Answer: Option (3) is the correct answer.

Explanation:

When a more reactive element or atom replaces a less reactive atom then this type of reaction is known as single displacement reaction.

In the given reaction, potassium iodide reacts with fluorine and results in the formation of potassium fluoride and iodine.

Here, fluorine being more reactive displaces iodine from potassium iodide.

Therefore, it is a single replacement or displacement reaction.

Feliz [49]

Answer:

Step 3

Explanation:

I am back sorry it took me so long, I believe its Step 3 because that's were you chose your strategy, you use it in Step 4, but if its not Step 3 its Step 4

1. identifying

problem solving step: 1)__ the problem is most difficult: not in habit of asking what the problem really is; in the habit of reacting or giving up

2. representing

problem solving step: 2) __ the problem: abstract or external representation

3. strategy

problem solving step: 3) selecting an appropriate __; trial and error vs means-ends analysis

4. implementing

problem solving step: 4) __ the strategy; dependent on previous steps
