Answer:
1.17 L
Explanation:
Step 1: Given data
- Initial volume (V₁): 1.50 L
- Initial pressure (P₁): 1.10 atm
- Initial temperature (T₁): 25 °C
- Final pressure (P₂): 1.50 atm
- Final temperature (T₂): 45 °C
Step 2: Convert the temperatures to the Kelvin scale
We will use the following expression.
K = °C + 273.15
K = 25°C + 273.15 = 298 K
K = 45°C + 273.15 = 318 K
Step 3: Calculate the final volume of the neon gas
If we assume ideal behavior, we can calculate the final volume of the neon gas using the combined gas law.
P₁ × V₁ / T₁ = P₂ × V₂ / T₂
V₂ = P₁ × V₁ × T₂ / T₁ × P₂
V₂ = 1.10 atm × 1.50 L × 318 K / 298 K × 1.50 atm = 1.17 L
Answer:
1.5 litre of C5H12 produce 9 litre of water vapour;
Explanation:
First balance the combustion reaction;
→ 
from the balance reacion it is clearly that,
one mole of C5H12 reacts completely with 8 mole of O2 gas;
Hence
one litre of C5H12 reacts completely with 8 litre of O2 gas;
there fore 1.5 litre C5H12 needs 12 litre oxygen gas but we have 15 litre.
so,
C5H12 is a limiing reactant and O2 is a excess reactant.
so quantity of H2O depends on limiting reactant;
one litre of C5H12 produce 6 litre of water vapour;
therefore,
1.5 litre of C5H12 produce 9 litre of water vapour;

Where do the hydrogen and oxygen atoms come from that become part of the glucose molecule made during photosynthesis? The oxygen molecules come from carbon dioxide and water. The hydrogen atoms come from water.
Hope this helps.
