Answer:
Well ads I remember, the motion of the gas particles is random and in a straight-line. A sample of gas is contained in a closed rigid cylinder.
And here is what I found too -
According to Kinetic Molecular Theory, gaseous particles are in a state of constant random motion; individual particles move at different speeds, constantly colliding and changing directions. We use velocity to describe the movement of gas particles, thereby taking into account both speed and direction.
Body temperature is the main one. blood ph is very important. and reflex reactions. if this was right please give me brainliest
Answer is: the average atomic mass of 125 atoms of uranium is 235.88.
ω(U-234) = 10 ÷ 125.
ω(U-234) = 0.080.
ω(U-235) = 75 ÷ 125.
ω(U-235) = 0.60.
ω(U-238) = 40 ÷ 125.
ω(U-238) = 0.320.
Average atomic mass of atoms of uranium =
Ar(U-234) · ω(U-234) + Ar(U-235) · ω(U-235) + Ar(U-238) · ω(U-238).
Average atomic mass of atoms of uranium =
234 · 0.08 + 235 · 0.6 + 238 · 0.32.
Average atomic mass of atoms of uranium = 18.72 + 141 + 76.16.
Average atomic mass of atoms of uranium = 235.88.
