Answer: The correct answer is Heterogeneous mixture
Explanation:
Heterogeneous mixture are those mixture in which:
- Substance is distributed in non uniform manner.
- Two distinct layers are formed
Thus when water and dirt are mixed together it results in the formation of a heterogeneous mixture and after sometimes two different layers will be observed.
Hence, in the bottle there is a heterogeneous mixture of water and dirt.
Answer:
The answer is C.
Explanation:
This is because you wouldn't be able to function without your lungs and spine. So therefore the answer would have to be "C".
Answer:
Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)
Explanation:
Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.
PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T
Density = 0.900 grams/L
R = 0.08206 L·atm/mole·K
T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)
= 20.1 g/mol => Neon (Ne)
All sodium compounds show the same coloured flame because sodium’s familiar bright orange-yellow flame colour results from promoted electrons falling back from the 3p1 level to their normal 3s1 level. The exact sizes of the possible jumps in energy terms vary from one metal to another.
A solution that has the capacity to hold additional solute at a certain temperature is called Under-saturated.
