How many oxygen atoms are in 2(NO3)
torisob [31]

6 Oxygen atoms

Explanation:

In the molecule 2(NO₃):

An atom is the smallest indivisible particle of any substance. They chemically combine to give compounds and molecules. Some of them are able to exist on their own.

An element is a substance that has a unique atom.

      NO₃ has two elements: N   and O

      Number of atoms:

    N = 1

    O = 3

but we have two moles of NO₃

 O = 3 x 2 = 6

 N = 1 x 2 = 2

12) Which particle has the most energy? A) ice B) water C) steam D) there is no difference in particle energy

Steam has more energy than Ice and Water because the particles in ice are close together, the particles in water flow more loosely than in a solid like ice and in steam they are very active.

MrRa [10]

Explanation:

In the context, a vial which is used in store medical samples is filled with water at room temperature. And the vial is kept on a cold water. Also a water bag containing warm water is kept near the vial.

The cold water kept at the bottom of the vial is having lower kinetic energy while warm water will have higher kinetic energy than the others. Since the water in the vial is at room temperature and it is in touch with the cold blue water, the water in the vial will loose or give its temperature to the cold blue water through conduction as well as convection process since temperature always flows from a hot body towards the cold body.

On the other hand, the warm water placed next tot he vial will give its temperature to the atmosphere.
