Answer:

Explanation:

All but kg can be vector quantities.

m/s^2 is acceleration. in the formula F = m*a the acceleration has direction and that means that force has direction. If you place an object on a table, there are 2 vectors in operation: one tends to move down (gravity) and one points up (the table top). The object would like to move but cannot, because the forces are equal but in opposite directions.

meters can be a vector or the unit of a vector. It is called displacement when it has direction.

km / hr. Since meters can be a vector, so can km. This is a velocity (or can be). When the direction is not specified, km/hr is a speed. It might describe the movement of a snail.  hours really have no direction. hours can't go up, or down or left or right, the way km can. So hours add nothing to the question.

kg are units of mass. Mass really has no direction associated with it. Don't confuse mass and weight. Weight does have a direction, but mass does not.

Sedaia [141]

Some of the things I would do after winning a $500 prize would be:

  • If I won the prize, I would travel to the beach to take a break.
  • If I won the prize, I would buy a bike for fun.
  • If I won the award, I would invite my wife to dinner at a restaurant.
  • If I won the prize, I would give my father a new car.
  • If I won the prize, I would donate a part to animal care foundations.

<h3>What is a conditional?</h3>

Conditional sentences are a type of sentence that is characterized by having a verb conjugated in the conditional. This verb tense is used to express:

  • Probabilities
  • Proposals
  • Doubts
  • Wishes

To write a sentence in the conditional tense, we must specify what event must happen and the immediate cause or the action that we would do after that condition occurs.

Some examples of conditional sentences with the context of the award obtained for the study of biodiversity in Peru would be:

  • If I won the prize, I would travel to the beach to take a break.
  • If I won the prize, I would buy a bike for fun.
  • If I won the award, I would invite my wife to dinner at a restaurant.
  • If I won the prize, I would give my father a new car.
  • If I won the prize, I would donate a part to animal care foundations.

How many moles of neon would be contained in 4.0 l of neon gas at 2 atm and 127oc?
Sergeeva-Olga [200]

If the pressure, volume, and temperature are 202650 Pa, 0.004 cubic meters, and 400.15 K. Then the number of the mole is 0.24 mol.

<h3>What is thermodynamics?</h3>

It is a branch of science that deals with heat and work transfer.

We know that the Ideal gas equation is given as

PV = nRT

Where

P = Pressure (Pa)

V = Volume (in m³)

n = Number of moles (mol)

R = universal gas constant (8.314 J⋅K⁻¹⋅mol⁻¹)

T = temperature (in K)

We have

P = 2 atm = 202.65 × 10³ Pa

V = 4 liters = 0.004 m³

T = 127 °C = 400.15 K

Then we have

Then the number of the mole will be

\rm n = \dfrac{PV}{RT}\\\\\\n = \dfrac{202.65 \times 10^3 \times 0.004}{8.314 \times 400.15}\\\\\\n = \dfrac{810.6}{3326.85}\\\\\\n = 0.24365 \approx 0.24
