Which bond would require more energy to break apart? (Short bond or Long bond). Explain

Semmy [17]

Answer:

shorter bond, because charges are close apart

Explanation:

shorter the bond length more is the energy required to break the bond for example if you take three pencils of different sizes one longer One medium sized One Shot sized if you try to break them the longer pencil will break much faster than the other two because the greater the length the lesser the strength the lesser energy you need to apply to break them apart ...

The drop-counter is misaligned with the buret, causing it to miss counting every one out of five drops of base added to the HCl.

Airida [17]

Answer:

Less than

Explanation:

According to the question, the drop counter is counting four out of five drops of base added to the HCl. So when the titration will reach to the end point the volume of Base recorded will be less than the actual volume of the base dropped in the solution.

We will use law of equivalence for the calculation of concentration of HCl,

$M_1V_1 = M_2V_2$

Where, $M_1$ and $V_1$ are molarity and volume of HCl and $M_2$ and $V_2$ are molarity of volume of the base added.

Thus concentration of HCl will be calculated as,

$M_1=\frac{M_2V_2}{V_1}$

As the recorded $V_2$ is less than the actual amount present in the solution, the calculated value of concentration of HCl will also be less than the actual.

B

Gemiola [76]

Answer: 1. magnesium hydroxide + sulfuric acid = magnesium sulphate + water

2. calcium hydroxide + hydrochloric acid = calcium chloride + water

3. lead hydroxide + nitric acid = lead nitrate + water

4. sodium hydroxide + sulfuric acid = sodium sulphate + water

5. potassium hydroxide + citric acid = potassium citrate + water

6. silver hydroxide + hydrochloric acid = silver chloride + water

7. aluminium hydroxide + phosphoric acid = aluminium phosphate + water

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The balanced chemical equations are :

1. magnesium hydroxide + sulfuric acid = magnesium sulphate + water

$Mg(OH)_2(aq)+H_2SO_4(aq)\rightarrow MgSO_4(aq)+2H_2O(l)$
