A student performs an experiment in which two blocks, block x of mass 2kg and block y of mass 3kg, are tied together by a rope. The system containing block x and block y is dropped above earth’s surface in the orientation shown in figure 1. A motion detector below each block collected data that were graphed to show the velocity as a function of time for blocks x and y as they fell toward the ground. The graphs are shown in figure 2 and figure 3, respectively. The positive direction is considered to be down. The change in momentum for the system containing block x and block y is most nearly

Answers

Answer 1

The change in momentum for the system containing both blocks will be 250 kg m/s.

How to calculate the momentum?

The momentum of an object simply means the product of the mass and the speed of the object.

In this case, the change in momentum will be:

P = (2 + 3)50

P = 5 × 50

P = 250 kg m/s

In conclusion, the change in momentum is 250 kg m/s.

Calculate the concentration of the lactate ion in a solution that is 0.100 mm in lactic acid ( ch3ch(oh)coohch3ch(oh)cooh , pkapka = 3.86) and 0.080 mm in hclhcl .

Answers

Lactic acid ⇒ H+ + Lactate
pKa = 3.86

Ka = 1.38 x 10^-4 would be equal to [H+] [lactate] / [lactic acid]

HCl ⇒ H+ + Cl-
[H+] = 0.08

Lactic acid = 0.10 M

1.38 x10^-4 would be equal to 0.08 [Lactate] / 0.10

Lactate = 0.10(1.38 x 10^-4/ 0.08
Lactate = 1.73 x 10^-4

Ab2 is a molecule that reacts readily with water. Calculate the bond energy of the a–b bond using the standard enthalpy of reaction and the bond energy data provided. Enter a number in kj to 0 decimal places

Answers

By using the standard enthalpy of reaction, the bond energy of the (A-B) bond is equal to 152.25 kJ/mol.

The balanced chemical equation.

[tex]AB_2[/tex] is a molecule that reacts readily with water ([tex]H_2O[/tex]) as represented by this properly balanced chemical equation:

                              [tex]2AB_2 +2H_2O \rightarrow O_2 +4HB+A_2\; \Delta H = -142\;kJ[/tex]

Bond:                              O–H       O=O           H–B       [tex]A \rightarrow A^+[/tex]

Bond energy (kJ/mol):   467         498             450         321      

The standard enthalpy of reaction.

Mathematically, the standard enthalpy of reaction can be calculated by using this formula:

[tex]\Delta H^{\circ}_R=\Delta H_{reactants}-\Delta H_{products}[/tex]

Substituting the given parameters into the formula, we have;

[tex]-142=[(2\times2(A-B)+(2\times2(O-H)-[(O=O)+4(H-B)+(A-A)]\\\\-142=4(A-B)+4(467)-498-4(450)-321\\\\-142=4(A-B)+1868-498-1800-321\\\\4(A-B)=-142-1868+498+1800+321\\\\4(A-B)=609\\\\(A-B)=\frac{609}{4}[/tex]
