Question

carbon, hydrogen, and oxygen atoms make up carbon dioxide gas and water, which are the reactants of photosynthesis. carbon, hydrogen, and oxygen atoms also make up glucose and oxygen gas, which are the products of photosynthesis. for every 6 molecules of carbon dioxide (co₂) that go into photosynthesis, the process requires 6 molecules of water (h₂o). complete the table.

type of atom	number of atoms in 6 molecules of carbon dioxide	number of atoms in 6 molecules of water	total number of atoms in reactants
c	6
o		6

Explanation:

Step1: Calculate H atoms in 6 CO₂

Carbon - dioxide has no hydrogen atoms, so number of H atoms in 6 molecules of CO₂ is 0.

Step2: Calculate H atoms in 6 H₂O

Each water molecule (H₂O) has 2 hydrogen atoms. So for 6 molecules of water, number of H atoms is $6\times2 = 12$.
Total number of H atoms in reactants is $0 + 12=12$.

Step3: Calculate C atoms in 6 H₂O

Water has no carbon atoms, so number of C atoms in 6 molecules of H₂O is 0. Total number of C atoms in reactants is $6+0 = 6$.

Step4: Calculate O atoms in 6 CO₂

Each CO₂ molecule has 2 oxygen atoms. So for 6 molecules of CO₂, number of O atoms is $6\times2=12$. Total number of O atoms in reactants is $12 + 6=18$.

Answer:

Type of atom	Number of atoms in 6 molecules of carbon dioxide	Number of atoms in 6 molecules of water	Total number of atoms in reactants
C	6	0	6
O	12	6	18
