Answer : The correct option is, (A) The box does not move.

Explanation :

Force : It is defined as the force can be a push or a pull.

Balanced force : When the two forces are equal in magnitude and in opposite direction. These forces are balance to each other. In this force, the object does not move.

Unbalanced force : When the two forces are not equal in magnitude and direction. These forces does not balance to each other. In this force, the object will move on that side where the force will be applied more.

There are three cases :

Case 1 : F_L=F_R

That means, when the force applied from left side are equal to the force applied from the right side then they balance to each other and object will not move.

Case 2 : F_L>F_R

That means, when the force applied from left side are more than the force applied from the right side then the object will move towards right side.

Case 3 : F_L

That means, when the force applied from left side are less than the force applied from the right side then the object will move towards left side.

According to question, the applied forces are equal in magnitude and in opposite direction. So, the box will not move.

Therefore, the correct answer is, A

Answer:

The answer is A.

Explanation:

The box does not move.

The forces are balanced so the box does not move.

A 99.8 mL sample of a solution that is 12.0% KI by mass (d: 1.093 g/mL) is added to 96.7 mL of another solution that is 14.0% Pb
andre [41]

Answer:

m_{PbI_2}=18.2gPbI_2

Explanation:

Hello,

In this case, we write the reaction again:

Pb(NO_3)_2(aq) + 2 KI(aq)\rightarrow PbI_2(s) + 2 KNO_3(aq)

In such a way, the first thing we do is to compute the reacting moles of lead (II) nitrate and potassium iodide, by using the concentration, volumes, densities and molar masses, 331.2 g/mol and 166.0 g/mol respectively:

n_{Pb(NO_3)_2}=\frac{0.14gPb(NO_3)_2}{1g\ sln}*\frac{1molPb(NO_3)_2}{331.2gPb(NO_3)_2}  *\frac{1.134g\ sln}{1mL\ sln} *96.7mL\ sln\\\\n_{Pb(NO_3)_2}=0.04635molPb(NO_3)_2\\\\n_{KI}=\frac{0.12gKI}{1g\ sln}*\frac{1molKI}{166.0gKI}  *\frac{1.093g\ sln}{1mL\ sln} *99.8mL\ sln\\\\n_{KI}=0.07885molKI

Next, as lead (II) nitrate and potassium iodide are in a 1:2 molar ratio, 0.04635 mol of lead (II) nitrate will completely react with the following moles of potassium nitrate:

0.04635molPb(NO_3)_2*\frac{2molKI}{1molPb(NO_3)_2} =0.0927molKI

But we only have 0.07885 moles, for that reason KI is the limiting reactant, so we compute the yielded grams of lead (II) iodide, whose molar mass is 461.01 g/mol, by using their 2:1 molar ratio:

m_{PbI_2}=0.07885molKI*\frac{1molPbI_2}{2molKI} *\frac{461.01gPbI_2}{1molPbI_2} \\\\m_{PbI_2}=18.2gPbI_2

Best regards.
