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:
Precision is good but accuracy is poor
Explanation:
The precision in a measure is about how close is a measured value to each other. In the problem, all measurements are between 15.33 and 15.34cm. Thus, you can say precision is good
And accuracy is about how close are the measured values to the theoretical or real value. The real length of the pencil is 15.85cm. The measurements are not even close of the real value. For that reason, you can sat accuracy of the measurements is poor.

Answer:
The density increases.
Explanation:
As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.
Answer:

Explanation:
It turns from turquoise to yellow or orange when it reacts with reducing sugars.
