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.

Explanation:

Step1: Calculate the number of H atoms in 6 molecules of CO₂

Carbon dioxide ($CO_2$) has no hydrogen ($H$) atoms. So, the number of $H$ atoms in 6 molecules of $CO_2$ is $0$.

Step2: Calculate the number of H atoms in 6 molecules of H₂O

Each water ($H_2O$) molecule has 2 $H$ atoms. For 6 molecules of $H_2O$, the number of $H$ atoms is $2\times6 = 12$.

Step3: Calculate the total number of H atoms in reactants

The total number of $H$ atoms in reactants is the sum of $H$ atoms from $CO_2$ and $H_2O$. Since $CO_2$ has 0 $H$ atoms and $H_2O$ has 12 $H$ atoms, the total is $0 + 12=12$.

Step4: Calculate the number of C atoms in 6 molecules of H₂O

Water ($H_2O$) has no carbon ($C$) atoms. So, the number of $C$ atoms in 6 molecules of $H_2O$ is $0$.

Step5: Calculate the total number of C atoms in reactants

The total number of $C$ atoms in reactants is the sum of $C$ atoms from $CO_2$ and $H_2O$. Given $CO_2$ contributes 6 $C$ atoms and $H_2O$ contributes 0 $C$ atoms, the total is $6+0 = 6$.

Step6: Calculate the number of O atoms in 6 molecules of CO₂

Each $CO_2$ molecule has 2 $O$ atoms. For 6 molecules of $CO_2$, the number of $O$ atoms is $2\times6=12$.

Step7: Calculate the total number of O atoms in reactants

The total number of $O$ atoms in reactants is the sum of $O$ atoms from $CO_2$ and $H_2O$. $CO_2$ has 12 $O$ atoms and $H_2O$ has 6 $O$ atoms (since each $H_2O$ has 1 $O$ atom and there are 6 molecules). So, the total 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	$12$	$6$	$18$
