Answer:
400000
Explanation:
First, figure out what 10^5 is. It is 100000. Then multiply it by 4 and there is your answer!
Also if it is 4x10^-5, it is 0.00004!
Oh yeah! If you want it to be in scientific notation, it is: 4x10^5
Since that I didn't quite understand what you are trying to question, it is either 4x10^5 or 4x10^-5!
The answer would be B) Absolute time.
Answer:
253.85 L
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O
From the balanced equation above, 4 moles of water vapor were produced.
Finally, we shall determine the volume of the water vapor produced as follow:
Mole water vapor (n) = 4 moles
Pressure (P) = 1 atm
Temperature (T) = 500 °C = 500 °C + 273 = 773 K
Gas constant (R) = 0.821 atm.L/Kmol
Volume (V) =?
PV = nRT
1 × V = 4 ×0.0821 × 773
V = 253.85 L
Thus, the volume of water vapor obtained is 253.85 L
