4. Law of superposition
Since you didn't have any extra information about the question I'll be presenting an example from my own textbooks that I've used.
An example of a direct observation is listening to a cricket chirp at night, and counting the number of chirps per minute.
Direct Observation is where the evaulator watches the subject in their usual habitat without disrupting or altering it.
The representative elements are elements where the s and p orbitals are filling. The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling, and the inner transition metals are the elements where the f orbitals are filling.
Answer:
To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction. If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced.
Answer:
The answer to your question is below
Explanation:
Law of conservation of mass:
mass of reactants = mass of products
Problem
mass of beakers before mixing = mass of beakers after mixing
Beaker A (128.71) + Beaker B (128.97) = Beaker A (154.1) + Beaker B (103.58)
257.68 g = 257.68 g
Then the law of conservation of mass is true
