Answer:
The tables show the relationships between x and y for two data sets.
Which statements describe the relationships between x and y in Data Set I and Data Set II?
Both data sets show additive relationships.
In Data Set I, y is 5.5 more than x , and in Data Set II, y is 5 more than x .
Data Set I shows a multiplicative relationship in which y is 5.5 times x .
Data Set II shows an additive relationship in which y is 20 more than x .
Both data sets show multiplicative relationships.
In Data Set I, y is 5.5 times x, and in Data Set II, y is 5 times x .
Data Set I shows an additive relationship in which y is 4.5 more than x .
Data Set II shows a multiplicative
Step-by-step explanation:
The amount of heat (in KJ) released when 3.5 moles of CH₄ react is 3115 KJ
<h3>Balanced equation</h3>
CH₄ + 2O₂ -> CO₂ + 2H₂O ΔH = 890 KJ
From the balanced equation above,
1 mole of CH₄ reacted to release 890 KJ of heat energy.
<h3>How to determine the heat energy released by 3.5 moles of CH₄</h3>
From the balanced equation above,
1 mole of CH₄ reacted to release 890 KJ of heat energy
Therefore,
3.5 moles of CH₄ will react ro release = 3.5 × 890 = 3115 KJ of heat energy
Thus, 3115 KJ of heat energy were released from the reaction
