Question

1. living oceans: food web

is the law of conservation of mass is illustrated in this diagram?
yes
no

Explanation:

Step1: Count atoms on reactant side

• Carbon: \(6\) (from \(6CO_2\))
• Oxygen: \(6\times2 + 6\times1=18\) (from \(6CO_2\) and \(6H_2O\))
• Hydrogen: \(6\times2 = 12\) (from \(6H_2O\))

Step2: Count atoms on product side

• Carbon: \(6\) (from \(C_6H_{10}O_6\))
• Oxygen: \(6+5\times2=16\) (from \(C_6H_{10}O_6\) and \(5O_2\))
• Hydrogen: \(10\) (from \(C_6H_{10}O_6\))

Since the number of atoms of each element is not the same on both sides of the equation, the Law of Conservation of Mass is not illustrated.

Answer:

NO
