High temp and low pressure
The volume is directly proportional to the absolute temperature so the answer is A.
Answer:
Higher concentration to an area of lower concentration
Explanation:
When you open a perfume bottle at a corner of a room, after a while, its fragrance can be perceived across a distance at the other end of the room. This is because, molecules of the compound in the fragrance have moved from the area of higher concentration in the perfume bottle, across a concentration gradient to a region of lower concentration at the other end of the room. This is diffusion.
Answer: 12 moles
Explanation: reaction C3H8+ 5 O2 ⇒ 3 CO2 + 4 H2O
1 mole propane produces 3 mol CO2. For 36 mol
Is 12 moles needed
This balanced equation shows us the ratios of reactants and products, so for every 3 oxygen molecules, we see that 4 iron atoms react as well. The answer is 4.
