how many total atoms are in 3NH4NO3=

Answers

Answer: 6 Nitrogen atoms, 12 Hydrogen atoms and 8 Oxygen atoms

Explanation:

Answer: 60 atoms

Explanation: To determine the number of atoms in 3NH4NO3, we need to first identify the number of atoms in one molecule of NH4NO3.

NH4NO3 consists of one nitrogen atom (N), four hydrogen atoms (H), and three oxygen atoms (O).

There are 2 nitrogen atoms and 6 oxygen atoms in 3 molecules of NH4NO3 because:

Each molecule of NH4NO3 has one nitrogen atom and three oxygen atoms, so three molecules have three nitrogen atoms and nine oxygen atoms in total.

However, there are two nitrogen atoms shared between the molecules, so there are only two distinct nitrogen atoms in the compound.

Next, each molecule of NH4NO3 contains four hydrogen atoms, so three molecules contain a total of 12 hydrogen atoms.

So the total number of atoms in 3NH4NO3 is:

2 nitrogen atoms x 3 + 12 hydrogen atoms x 3 + 6 oxygen atoms x 3 = 6 + 36 + 18 = 60.

Therefore, there are a total of 60 atoms in 3NH4NO3.

Explanation:

A student chemist created the following model to explain a phase change they observed at home: A chocolate bar was placed in a hot pan. The chocolate began to flow, and it took the shape of the pan. Explain the changes you would make to the model in order to correctly show what changed the chocolate molecules’ freedom of movement.

Answers

Answer:

Since the energy involved in a phase changes is used to break bonds, there is no increase in the kinetic energies of the particles, and therefore no rise in temperature.

Look at the food chain below. Which organism shown will get most of the available energy that is in the seeds?

Answers

Answer:

Explanation:

hawk or mouse

Answer: The mouse.

- Following the natural order of the food chain shown in the image, we can see that: The snake would eat the mouse and the hawk would most likely eat the snake. The arrow for the seeds are pointing dire to the mouse, which would let us know that the mouse is eating the seeds and will gain the most energy from them.
