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.
one product was O2 (oxygen gas). What was the evidence of this gas?
What is oxidation?
releases energy from the sun
releases energy from photosynthesis
releases energy from the food for us to use
releases energy from meat products for us to use
Answer:
It should be C. releases energy from the food for us to use.
Answer:
third one
Explanation:
Consider the energy pyramid. Which statement best summarizes what happens to energy as it flows through the food chain?
Answer:
B. The amount of energy transferred between trophic levels decreases up the food chain.
Explanation:
What forms as a result of the wind's frictional force on water?
A. deep sea currents that move in a path similar to the wind currents
B. surface currents that move in a path opposite to the wind currents
C. surface currents that move in a path similar to the wind currents
D. deep sea currents that move in a path opposite to the wind currents
Answer:
C. surface currents that move in a path similar to the wind currents
Explanation:
The wind's frictional force drags the surface of the ocean, causing the water to move in the same direction as the wind. The resulting surface currents can influence weather patterns and impact marine ecosystems. Deep sea currents are driven by differences in water temperature and salinity, and are not directly affected by the wind's frictional force on the surface of the ocean.
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.
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.
Explanation:
Consider the food chain shown in the diagram. What conclusion about decomposers can be drawn from the diagram?
Answer:
Some dead plants feed primary consumers (insects) which then feed the higher chains
Explanation:
The primary consumer eats the decomposing plant, giving it energy. Then the insect feeds energy to the other animals on the chain until it reaches the apex predator.
Look at the food chain below. Which organism shown will get most of the available energy that is in the seeds?
Answer:
Explanation:
hawk or mouse
