Complete question:
<em>Write the verbal statement as an equation using x as a variable. Then solve. 2 more than 3 times a number is 17.
</em>

The required expression is 3x + 2 = 17 and the value of x is 5
Let the unknown number be x
- 3 times a number is expressed as 3x
- 2 more than3 times the number is 3x + 2
If the result is equivalent to 17, the required expression will be 3x + 2 = 17
Solve the resulting expression:
3x + 2 = 17
3x = 17 - 2
3x = 15
x = 15/3
x = 5
Hence the required expression is 3x + 2 = 17 and the value of x is 5

Answer:
8.1 moles
Step-by-step explanation:
Given parameters: Mass of water to be decomposed = 29.2g Unknown: Number of moles of oxygen. Solution: To solve this problem, we first write the balanced reaction equation : 2H₂O → 2H₂ + O₂ Now convert the given mass of the water to number of moles; Number of moles of water = Molar mass of water = 2(1) + 16 = 18g/mol Number of moles of water = = 16.2moles From the balanced reaction equation: 2 moles of water produced 1 mole of oxygen gas; 16.2 mole of water will produce = 8.1moles of oxygen gas
