I pretty sure it's the pH level 7
The atomic radius is defined as one-half the distances between the nuclei of identical atoms that are bonded together.The atomic radius of an atom can be defined as one half the distance between two nuclei in a diatonic molecule.Atomic radii have been measured for elements.
Answer:
It matters
Explanation:
Pure substance are known to have a sharp freezing point. However, the presence of solute lowers the freezing point of the solvent. The best time to measure the freezing point is when the freezing process is just beginning.
It will be an error to measure the freezing point when the part of the solution has already frozen.
<span>You can work out the following:
Mass = Density x Volume
Density = Mass Ă· Volume
Volume = Mass Ă· Density
The density of gold is 0.670205 oz/cm^3
The volume is length x width x depth = 7*3*2 = 42
The answer is Mass = 0.670205 x 42 = 281 ounces</span>
They are classified as Decomposers
