Decomposition of sodium bicarbonate produces pure carbon dioxide and decomposition of hydrogen peroxide produces pure oxygen.
The amount of carbon dioxide in exhaled air is greater than that in regular air. Thus, the order is:
gas from decomposition of NaHCO₃ → Exhaled air → Air → gas from the decomposition of H₂O₂
It would be carbon because its relative atomic mass is 12

Answer:
375 grams of 4% NaOH solution contains 15 grams NaOH
Explanation:
Given 4% solution of NaOH = 4g NaOH/100 g Solution
=> 4g NaOH/100g Soln = 15 g NaOH / X
=> X = 15 g NaOH (100 g Soln) / 4 g NaOH = 375 grams Soln contains 15 g NaOH.
