Answer: Missing data related to question is attached below
If the KH,CH4 = 1.42 * 10^-3 mol/L atm
answer:
0.88 atm
Explanation:
P1 = 20 psi
aqueous concentration of methane in closed bottle = 20 ppm
20 ppm = 20 / 1000 ( gram / Kg ) = 0.020 gram/kg = 0.020 g/liter
molar mass of methane = 16 gram/mol
<em>next : convert mass conc to molar conc </em>
Cm = 0.020 / 16
Cm = 1.25 * 10^-3 mol/L
Given that KH,CH4 = 1.42 * 10-3 mol/L atm
Applying equilibrium relationship
Cm = ( KH,CH4 ) ( partial pressure of methane )
hence partial pressure of methane
= Cm / ( KH,CH4 ) = 1.25 * 10^3 / (1.42 * 10^-3 ) = 0.88 atm
1]Well if the planets were removed the pray would have no food to eat, because of this the food chain would most likely die out, or the pray would need to find a new location with materials they can consume.
2]Explain how energy is transferred through food chains and food webs in an ecosystem. Energy is transferred through the separate trophic levels of a food chain or web by feeding.The first trophic level (producers) is that of plants which are examples of autotrophs – they make their own food.
