Transcribed Image Text:## Question 18 of 39
### Problem Statement:
In the following reaction, how many moles of CH₃OH are required to give off 5576 kJ of heat?
Reaction:
2 CH₃OH (l) + 3 O₂ (g) → 2 CO₂ (g) + 4 H₂O (g)
ΔH° = -1280 kJ
### Calculation:
You need to calculate how many moles of CH₃OH are necessary to release 5576 kJ of heat, given that 1280 kJ of heat is released per 2 moles of CH₃OH.
### Interface Description:
Below the problem statement, there is an interface for inputting your answer. It includes:
- A numerical keypad with numbers 0-9 and a decimal point.
- A sign change button (for positive or negative values).
- A multiplication factor (x 10^□) for scientific notation.
- An option to clear the input (C) or delete the last entry (backspace).
To solve the problem, calculate the moles of CH₃OH needed and input your answer using the provided numerical interface.
