Electron because of the charge it has
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)
Answer:
The missing section of the candle burns away and evaporates while some drips and collects at the base.
Explanation:
This is because a chemical reaction is occurring due to the heat, causing the molecule in the candles wax to move around faster and faster therefore causing melting.
