The formula for citric acid, found in lemon juice, is CH2COOH

Question

. For each symbol, identify the element and the number of atoms present by dragging the tiles into the appropriate columns of the table.

carbon
hydrogen
oxygen
1
2
3
7

Answer 1

To identify the elements and the number of atoms present in the formula for citric acid (C₆H₈O₇), we can break it down as follows:

1. C: This represents Carbon (C). In citric acid, there are 6 carbon atoms.
2. H: This represents Hydrogen (H). In citric acid, there are 8 hydrogen atoms.
3. O: This represents Oxygen (O). In citric acid, there are 7 oxygen atoms.

Now, let's organize this into your requested columns:

| Element | Number of Atoms | |-----------|-----------------| | Carbon | 6 | | Hydrogen | 8 | | Oxygen | 7 |

If you need to drag tiles to match the counts, the correct associations are:

• Carbon: 6
• Hydrogen: 8
• Oxygen: 7
