If the product is ammonia, the reactants must be the diatomic gases N₂ and H₂. The complete balanced reaction is shown below:
<em>N₂ + 3 H₂ → 2 NH₃</em>
Now, the number of molecules on the left or reactant side are: 2 molecules of nitrogen and 3*3 = 6 molecules of hydrogen. <em>The total number would be 8 molecules. The same number of molecules is counted on the right or product side. </em>This is to obey the Law of Conservation of Mass.
Answer:
True
Explanation:
An orbital is is the space occupied by a pair of electrons. The maximum number of electrons in an orbital is 2.
The maximum number of electrons in in the orbitals are two.
For s-sublevel with one orbital we have two electrons
p-sublevel with three orbitals we have six electrons
d - sublevel with five orbitals we have ten electrons
f - sublevel with seven orbitals we have fourteen electrons
Each orbital can take a maximum of two electrons.
Answer:
The best practices officers should use when securing a crime scene is option D
D. They should secure a larger area than the actual crime scene
Explanation:
Officers should secure the scene by limiting access to the scene and movement within the scene
Three layers of secure perimeter should be used by officers to secure a crime scene, with the smallest inside perimeter being the actual crime scene
Next to the crime scene, is an inner perimeter which is the designated meeting point/command post
The outer perimeter, which is the third outer layer is to keep onlookers, passerby, and nonessential personnel at safety and out of the actual crime scene.
A mixture consists of numerous substances, whereas a substance does not consist of mixtures, but rather of compounds. Mixtures can be separated physically, while substances cannot.
