How many moles of lithium hydroxide are required to react with 19.2 mol CO2, the average amount exhaled by a person each day?
sladkih [1.3K]

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

2. When carbohydrates are oxidized, the C-H bonds of the carbohydrate become C=O bonds of carbon dioxide. Oxidation is defined a
Flauer [41]

Answer:

A) The shared electrons in C-O bonds spend less time close to the carbon nucleus than the shared electrons in C-H bonds.

Explanation:

The electronegativity from H is 2.2, from C is 2.55 and from O is 3.44. This property is the measure of the attractive force between an atom and a pair of electrons.

So, the difference of electronegativity of H and C is smaller than the difference between O and C. Because oxygen is more electronegative, the electrons stay close to it in the bond C=O. So carbon has a partial positive charge in that bond. For the bond C-H, the shared electrons stay closes to carbon.
