Answer:
C
Explanation:
Imcreased tmperature will speed up a reaction/process.
Asteroids are rocky space debris that are formed from interspacial collisions and collection of dusty particles. our solar system has an enormous asteroid belt between Mars and Jupiter.
Jupiter also has more local asteroids that are locked to its gravitational pull.
Not to be confused with a comet or meteor.
Answer: I'm thinking it should be either stay the same or decrease
Explanation: If the size is increasing then the sample should not increase but decrease or stay the same. Mainly the sample would do the opposite of what the size is doing
According to Raoult's low:
We will use this formula: Vp(Solution) = mole fraction of solvent * Vp(solvent)
∴ mole fraction of solvent = Vp(Solu) / Vp (Solv)
when we have Vp(solu) = 25.7 torr & Vp(solv) = 31.8 torr
So by substitution:
∴ mole fraction of solvent = 25.7 / 31.8 =0.808
when we assume the moles of solute NaCl = X
and according to the mole fraction of solvent formula:
mole fraction of solvent = moles of solvent / (moles of solvent + moles of solute)
by substitute:
∴ 0.808 = 0.115 / (0.115 + X)
So X (the no.of moles of NaCl) = 0.027 m
