Answer:
Baking soda = No. of atoms are 1 sodium + 1 Hydrogen + 1 carbon + 3 oxygens = 6 atoms per molecule.
B. Mn + NiBr₂ → Ni + MnBr₂
Explanation:
The reaction that can be predicted of all is Mn + NiBr₂ → Ni + MnBr₂.
The activity series is used to predict the products of single displacement reactions.
The series ranks metals in order of their reactivity. Those higher up in the series are highly reactive metals. Those at the bottom are slightly to non-reactive metals.
For a single displacement reaction to occur, a metal higher up in the activity series displaces one that is lower in the series.
Reaction A will not occur, Ba is higher in the series
Reaction C will not occur, Pt and Au are unreactive
Reaction D will not occur as Zn is lower in the series
Mn is higher in the reactivity series and it will displace Ni from the solution.

Answer:
1.602 moles CO
Explanation:
To convert from liters to moles, divide by 22.4:
35.88 L / 22.4 = 1.602 moles CO
