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.
One kilogram is equal to one thousand grams. Further, one gram is equal to 1000 mg. The conversion is as shown below,
(6.285 x 10³ mg) x (1 g / 1000 mg) x (1 kg / 1000 g)
The numerical value of the operation above is 0.006285 kg.
Son átomos que tienen el mismo número atómico, pero diferente masa atómica. Es decir, contienen el mismo número de protones pero difieren en el número de neutrones. Como ejemplo, tendríamos el Hidrógeno y sus 3 isótopos, el Protio, el Deuterio y el Tritio.
The operating properly of a chemical plant would have to the same property of any chemicals but its in a plant form instead of test tubes it would have a stem and leaves and you could squeaz the plant and get it out of the plant
