Answer:
4. The carbon in the ocean circulates through the water and is released by anaerobic respiration.
Explanation:
Carbon cycle involves the transfer of carbon between the atmosphere (air) hydrosphere (water), biosphere (living organisms) etc. Carbon in form of carbon dioxide enters into water bodies e.g ocean via diffusion, which is used by aquatic plants for photosynthesis.
The carbon dioxide is then released when some set of living organisms undergo anaerobic respiration. Hence, carbon in the ocean circulates through the water and is eventually released into the atmosphere when organisms undergo respiration.
Yes, the formation of 1 mol of NH3 from H2 and N2 differ from Q for the formation of NH3 from H2 and 1mol of N2
Solution:
Equation for the formation of 1 mol of NH3
3/2H2(g)+ 1/2N2(g) → NH3(g)
The Q of this reaction is
Q1 = [product] / [reactant]
Q1 = [NH 3 ] / [H2]^3/2 [N2]^1/2
Equation for the formation of NO3 from 1 mol of N2
3H 2 (g) + N2(g) → 2NH 3(g)
The Q of this reaction
Q 2 = [product] / [reactant]
Q 2 = [NH 3 ]^2 / [H 2 ]^3 [N 2 ]
The relationship between the two Q's is
(Q1)^2 = Q2

What is the acceleration of a 10 kg mass pushed by a 5 N force? The acceleration due to gravity on the moon is 1.6 m/s2. Your mass is 60 kg.
0.025 mg = 25E-3 g Pb.
<span>mols Pb = grams Pb/atomic mass Pb. </span>
<span>1000 mL H2O x 1.00 g/mL = 1000 g = 1 kg. </span>
<span>molality = mols Pb/kg H2O
