Determine the mass of oxygen necessary to react with 2.3 moles of HCl
Orlov [11]
4HCl + O₂  →  2Cl₂  +  2H₂O

mole ratio of HCl  :  O₂  is   4  :  1

∴ if moles of HCl = 2.3 mol

then mol of O₂ =  2.3 mol  ÷  4
                        = 0.575 mol

mass of O₂  =  moles of O₂ × molar mass of O₂
                    =  0.575 mol ×  (16 × 2) g/mol
                    =  18.4 g

aleksley [76]

Answer:

It will require<u> second round</u> of the cycle to release 14C0_2

Explanation:

<u>Reason behind the requirement of second round of the cycle to release </u>CO_2 -:

The C4 carbon of succinyl CoA is acetyl from acetyl CoA. Succinyl CoA is converted to succinate, which is then converted to fumarate, fumarate, malate, and eventually oxaloacetate. 14C will be found in oxaloacetate at either C1 or C4. During the second round of the loop, each of these carbons will be converted to carbon dioxide.
