<h2>Answer:</h2>
The volume of water measured using the graduated cylinder is <em>not exactly identical </em> identical to the volume calculated.
<h3>Explanation:</h3>
Calculated volume is theoretical value calculated from the density and mass of water.
But volume measured in cylinder can contain the personal error of individual.
Because in graduated cylinder volume is measured in a specific way that is:
- Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid.
- The liquid will tend to curve downward.
- This curve is called the meniscus.
- Always read the measurement at the bottom of the meniscus.

<u>Answer</u>:
balanced equation: CH₄ + 2O₂ → CO₂ + 2H₂O
<u>Explanation</u>:
Given sample: CH₄ + O₂ → CO₂ + H₂O
- The carbon is same, so no need to change.
- Hydrogen 2 less on left side so putted "2" before H₂O = "2H₂O"
- so now, there is total 4 oxygen on left side to balance put 2 before right side oxygen like this "2O₂"
changes applied: CH₄ + <u>2</u>O₂ → CO₂ + <u>2</u>H₂O
