I think I would agree on horses, just because you can take them for lessons, ride them treat them like a pet. Donkeys you can’t ride but you can have as a pet. Horses you can make money off, like races, but aren’t influenced. You can rent out horses to people that don’t have anywhere to place them.
Answer:
atoms or molecules
Explanation:
Gas particles are constantly bumping into each other and the borders of their container.
Density should be your answer. Density is the measure of a mass per unit volume.
Combustion reaction occurs when organic compound reacts with oxygen to form CO₂, H₂O and energy
C(s) + O₂(g) → CO₂(g) is Synthesis reaction not combustion
2 H₂(g) + O₂(g) → 2 H₂O(g) also Synthesis reaction and not combustion
C₃H₈(g) + 5 O₂ → 3 CO₂(g) + 4 H₂O(g) is considered as Combustion reaction
2 C₃H₇OH(l) + 9 O₂(g) → 6 CO₂(g) + 8 H₂O(g) Combustion reaction
Answer:
The answer to your question is P2 = 342 kPa
Explanation:
Data
Pressure 1 = P1 = 155 kPa
Volume 1 = V1 = 22 l
Pressure 2 = P2 = ?
Volume 2 = V2 = 10 l
Temperature = constant
Process
1.- Write the equation of the combined gas law
P1V1/T1 = P2V2/ T2
Cancel T1 and T2 because they measure the same
P1V1 = P2V2
-Solve for P2
P2 = P1V1/V2
2.- Substitution
P2 = (155 x 22) / 10
3.- Simplification
P2 = 3410 / 10
4.- Result
P2 = 342 kPa
