Answer:
N2+O2→2NO
Explanation:
Dalton’s atomic theory is based on law of constant composition and law of conservation of mass.
One of the postulates of this theory is that rearrangement of atoms occurs during a chemical reaction. In other words, only rearrangement of elements occurs during a chemical reaction and elements remain the same.
So, among the given, the following reaction undergoes rearrangement of elements.
N2+O2→2NO
SO, only the above reaction is possible as per Dalton’s atomic theory.

Answer:
42.0g/mol
Explanation:
The steps for this question is to use the ideal gas law, and then use n=m/M to find molar mass.
PV = nRT
n= PV/RT
Change 23 degrees to 296.15 K and 684mmHg to kpa
n = (91.1925kpa)(2.00L)/(8.314Lkpa/mol K)(296.15K)
n= 0.074mol
n = m/M
M = m/n
M = 41.98489g/mol
