Answer: 12 moles
Explanation: reaction C3H8+ 5 O2 ⇒ 3 CO2 + 4 H2O
1 mole propane produces 3 mol CO2. For 36 mol
Is 12 moles needed
as you move in the periodic table from left to right he atomic radius decreases...
this is how they are avenged in periodic table, now you can answer which is having smaller radius and also which has larger radius

Answer:
6.24 x 10-3 M
Explanation:
Hello,
In this case, for the given dissociation, we have the following equilibrium expression in terms of the law of mass action:
![Ka=\frac{[H_3O^+][BrO^-]}{[HBrO]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH_3O%5E%2B%5D%5BBrO%5E-%5D%7D%7B%5BHBrO%5D%7D)
Of course, water is excluded as it is liquid and the concentration of aqueous species should be considered only. In such a way, in terms of the change
, we rewrite the expression considering an ICE table and the initial concentration of HBrO that is 0.749 M:

Thus, we obtain a quadratic equation whose solution is:

Clearly, the solution is 0.00624 M as no negative concentrations are allowed, so the concentration of BrO⁻ is 6.24 x 10-3 M.
Best regards.
