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
Answer:
a. 
b. 
Explanation:
Hello.
In this case, according to the balanced chemical reaction, we can write the law of rate proportions:

Thus, we proceed as follows:
a. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:

b. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:

Best regards!
Answer:
Color Changes. A change in color often indicates a chemical change.
Temperature Changes. Changes in temperature might also indicate a chemical change has occurred.
Precipitates. The formation of a precipitate is a sign that a chemical change has occurred.
Light Emission.
Gas Production.
Explanation:
Well cars need gas to run on if the car does not have gas it wont run and you cant get to places you need to go only if you have gas.
