Answer:
V = 122.2 L
Explanation:
Given data:
Number of molecules of water = 6.58×10²⁴
Volume of oxygen produced = ?
Solution:
Chemical equation:
2H₂O → 2H₂ + O₂
<em>Number of moles of water:</em>
Number of moles = 6.58×10²⁴/ 6.022 ×10²³
Number of moles = 1.09 ×10¹ mol
Number of moles = 10.9 mol
Now we will compare the moles of water with oxygen:
H₂O : O₂
2 : 1
10.9 : 1/2×10.9 = 5.45 mol
Volume of oxygen:
PV = nRT
V = nRT/P
V = 5.45 mol × 0.0821 L. atm. K⁻¹. mol⁻¹× 273 k / 1 atm
V = 122.2 L. atm. / 1 atm
V = 122.2 L
The population will get low because the food we eat is animals which is species then the animals that eat that prey will die off because that might be there only prey....then if more species is gone there will be nothing left
I Hope this helped

Answer:
V₂ = 918.1 cm³
Explanation:
Given data:
Initial volume = 640 cm³
Initial temperature = 100°C (100+273 = 373 K)
Initial pressure = 1490 mmHg (1490 /760 = 1.96 atm)
Final volume = ?
Final temperature = 273 K
Final pressure = 1 atm
Solution:
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
now we will put the values in formula.
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 1.96 atm × 640 cm³ × 273 K / 373 K × 1 atm
V₂ = 342451.2 atm .cm³ . K / 373 K. atm
V₂ = 918.1 cm³
