An indicator species is an organism whose presence, absence, and abundance reveals a specific environmental condition, whether it be a positive or negative condition.
Answer:
0.665 moles of CO₂
Explanation:
The balance chemical equation for the combustion of Ethane is as follow:
2 C₂H₆ + 7 O₂ → 4 CO₂ + 6 H₂O
Step 1: <u>Calculate moles of C₂H₆ as;</u>
Moles = Mass / M.Mass
Putting values,
Moles = 10.0 g / 30.07 g/mol
Moles = 0.3325 moles
Step 2: <u>Calculate Moles of CO₂ as;</u>
According to balance chemical equation,
2 moles of C₂H₆ produced = 4 moles of CO₂
So,
0.3325 moles of C₂H₆ will produce = X moles of CO₂
Solving for X,
X = 0.3325 mol × 4 mol ÷ 2 mol
X = 0.665 moles of CO₂
Answer: The boiling point.
Explanation: Once water heats to a boil, it evaporates, turning into water vaper. This is the process in which is called vaporization. Hope that answered your question

V = 3 x 1 x 1.5 = 4.5 cm^3
m = d x V
= 19.32 x 4.5
= 86.94g
