I think you forgot to give the options along with the question. I am answering the question based on my knowledge and research. "Test a third group that does not receive the supplement" would be the procedure that would have made the <span>outcome of this study more valid. I hope the answer helps you.</span>
At decomposition of solid substance with formation of gas leads to increase in an entropy. For example,
60°C
NH₄NO₂(s) = N₂(g) + 2H₂O(l)
true
C₁ * V₁ = C₂ * V₂
1.0 * 20 = C₂ * 60
20 = C₂ * 60
C₂ = 20 / 60
C₂ = 0.33 M
hope this helps!
