Answer:
38.4 mol LiOH
Explanation:
Step 1: Write the balanced neutralization equation
2 LiOH + CO₂ ⇒ Li₂CO₃ + H₂O
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of LiOH to CO₂ is 2:1.
Step 3: Calculate how many moles of lithium hydroxide are required to react with 19.2 mol CO₂
19.2 mol CO₂ × 2 mol LiOH / 1 mol CO₂ = 38.4 mol LiOH
The correct answer is A. Chemical change turns food into a new form, a form that cells can use. It happens because the food we eat cannot be processed by cells so several reactions inside our body allow chemical changes to the food we ate turning them to usable compounds for our cells.
Corrosion is the gradual destruction of materials by chemical reaction with the environment.It can be prevented by galvanisation.

This ability of water is called a capillary action. This ability is exhibited by liquids where they flow in tubes without any assistance. This happens due to adhesion, cohesion and surface tension.
