Three friends were kicking soccer balls at a neighborhood field. Three soccer balls were rolling across the field. The black soc

cer ball has less mass than the blue and orange balls, which have equal mass. All three soccer balls were kicked by one of the friends, but not all from the same direction. Use the information in the diagram to answer.
Which soccer ball(s) experienced the strongest force? How do you know?

A. All three soccer balls experienced the same force because they changed speed by the same amount.

B the orange soccer ball it has more mass and the fastest ending speed

c. the blue soccer ball it takes a stronger force to slow down a more massive object than to speed it up.

D the blue and orange soccer balls they have more mass than the black soccer ball changed speed by the same amount

What would be the freezing point of a solution that has a molality of 1.324 m which was prepared by dissolving biphenyl (C12H10)
lbvjy [14]

The freezing point of a 1.324 m solution, prepared by dissolving biphenyl into naphthalene, is 71.12 ° C.

A solution is prepared by dissolving biphenyl into naphthalene. We can calculate the freezing point depression (ΔT) for naphthalene using the following expression.

\Delta T = i \times Kf \times m =   1 \times 6.90 \°C/m  \times 1.324m = 9.14  \°C

where,

  • i: van 't Hoff factor (1 for non-electrolytes)
  • Kf: cryoscopic constant
  • m: molality

The normal freezing point of naphthalene is 80.26 °C. The freezing point of the solution is:

T = 80.26 \° C - 9.14 \° C = 71.12 \° C

The freezing point of a 1.324 m solution, prepared by dissolving biphenyl into naphthalene, is 71.12 ° C.

A compound is formed when 171.2 g of carbon reacts with 28.8 g of hydrogen. What is the mass percent of hydrogen in the compound
IgorLugansk [536]
Following the law of conservation of mass, the mass percent of hydrogen in the resulting compound is 14.4%(wt/wt). This is assuming that all of the carbon reacts with all of the hydrogen. The solution is as follows:

mass % = mass hydrogen*100/total mass = 28.8*100/(28.8+171.2) = 14.4%
