Answer:
Bacteria are vital in keeping nitrogen cycling through the ecosystem, and nitrogen is vital to plant growth. Without bacteria around to break down biological waste, it would build up. And dead organisms wouldn't return their nutrients back to the system
Explanation:
Answer:
A
Explanation:
CH4+O2-CO2+ H20
that mean methane has burn in oxygen to produce CO2
Answer:
1.71atm
Explanation:
The following were obtained from the question:
V1 (initial volume) = 6L
P1 (initial pressure) = 1atm
V2 (final volume) = 3.5L
P2 (final pressure) =?
Using the Boyle's law equation:
P1V1 = P2V2, the final pressure can be obtained as follow:
P1V1 = P2V2
1 x 6 = P2 x 3.5
Divide both side by 3.5
P2 = 6/3.5
P2 = 1.71atm
The final i.e the new pressure inside the piston is 1.71atm
Explanation:
Acidic pH can be between 0 and 6. Hence the answer is D.
7 is neutral whereas 10 and 14 are basic.
