Question

for every 6 molecules of carbon dioxide gas (co₂) and 6 molecules of water (h₂o) that go into photosynthesis, the process produces 1 molecule of glucose (c₆h₁₂o₆) and 6 molecules of oxygen gas (o₂).
complete the table.

Explanation:

Step1: Find the number of H atoms in 1 glucose molecule

The formula of glucose is \(C_6H_{12}O_6\). For hydrogen (\(H\)), the sub - script is 12. So, the number of \(H\) atoms in 1 molecule of glucose is 12.

Step2: Calculate the total number of H atoms in products

Since there is no \(H\) in oxygen (\(O_2\)) and 1 glucose molecule has 12 \(H\) atoms, the total number of \(H\) atoms in products (1 glucose molecule) is 12.

Step3: Find the number of O atoms in 1 glucose molecule

In the formula \(C_6H_{12}O_6\), for oxygen (\(O\)), the sub - script is 6. So, the number of \(O\) atoms in 1 molecule of glucose is 6.

Step4: Calculate the number of O atoms in 6 oxygen molecules

The formula of oxygen is \(O_2\). One molecule of \(O_2\) has 2 \(O\) atoms. For 6 molecules of \(O_2\), the number of \(O\) atoms is \(6\times2 = 12\).

Step5: Calculate the total number of O atoms in products

The total number of \(O\) atoms in products is the sum of \(O\) atoms in glucose and \(O\) atoms in oxygen. So, it is \(6 + 12=18\).

Step6: Calculate the total number of C atoms in products

Since there is no \(C\) in oxygen (\(O_2\)) and 1 glucose molecule has 6 \(C\) atoms, the total number of \(C\) atoms in products (1 glucose molecule) is 6.

Answer:

Type of atom	Number of atoms in 1 molecule of glucose	Number of atoms in 6 molecules of oxygen	Total number of atoms in products
\(C\)	6	0	6
\(O\)	6	12	18
