Answer:
C
Explanation:
Here's an example of displacement reaction:
2 Al (s) + 3 CuSO4 (aq) -> 3 Cu (s) + Al2(SO4)3 (aq)
note that aluminium and copper are elements,
copper II sulphate and aluminium sulphate are compound
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
The answer is:
- Low power output
- Thick exhaust fumes
Due to little oxygen, the fuel does not burn completely and therefore only a small proportion of power of the fuel is harnessed to turn the pistons. This can even cause the engine to stall. Due to incomplete combustion, because there is more fuel than oxygen in each combustion cycle, the exhaust will be darker due to unburned carbon.
Well a molecule of water is equal to 1 Oxygen and 2 Hydrogen each, so it'd be 2 molecules of water
Biomass is a renewable source of fuel to produceenergy because: waste residues will always exist – in terms of scrap wood, mill residuals and forest resources; and. properly managed forests will always have more trees, and we will always have crops and the residual biological matter from those crops.<span>
