Answer:
The tropic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The tropic level of an organism is the number of steps it is from the start of the chain.

Answer:
1.8 g
Explanation:
Step 1: Write the balanced equation
CH₃CH₃(g) + 3.5 O₂(g) ⇒ 2 CO₂(g) + 3 H₂O(g)
Step 2: Determine the limiting reactant
The theoretical mass ratio of CH₃CH₃ to O₂ is 30.06:112.0 = 0.2684:1.
The experimental mass ratio of CH₃CH₃ to O₂ is 0.60:3.52 = 0.17:1.
Thus, the limiting reactant is CH₃CH₃
Step 3: Calculate the mass of CO₂ produced
The theoretical mass ratio of CH₃CH₃ to O₂ is 30.06:88.02.
0.60 g CH₃CH₃ × 88.02 g CO₂/30.06 g CH₃CH₃ = 1.8 g
It most likely contains copper :)
Answer:
Rate of reaction = 2.0 M/s
Explanation:
2H2O2(g) --> 2H2O(g) + O2(g)
Rate of formation of H2O = 2.0 M/s
Rate of reaction can be measured using multiple techiques and parameters like volume, pressure etc.
Among these techniques is the measurement of appearance of products.
This means we have;
Rate of reaction = Rate of appearance of product
Hence;
Rate of reaction = 2.0 M/s
