ANSWER:
all of them
Explanation:
preciseness is measured by how many decimal places are used not by accuracy. since all of these are to the same decimal place they are all equally precise even if they are inaccurate.
Answer:
See explanation
Explanation:
Number of protons = 28
Number of neutrons = 28
Mass of each proton = 1.007277 amu
Mass of 28 protons = 28 * 1.007277 amu = 28.203756 amu
Mass of each neutron = 1.008665 amu
Mass of 28 neutrons = 28 * 1.008665 amu = 28.24262 amu
mass defect of nickel-56 = 0.4667 amu
Binding energy = Δmc^2
Binding energy = 0.4667 *(3 * 10^8)^2
Binding energy =4.2 * 10^16 J
Binding energy per nucleon = 4.2 * 10^16 J/56
Binding energy per nucleon = 7.5 * 10^14 J
Explanation:
The physical properties of matter tells us everything about the substance when no change is occurring to its constituents.
We observe such properties with our senses or instruments or some apparatus.
Examples are boiling point, melting point, density, viscosity, spectroscopic patterns, state of matter, odor, taste, hardness, texture etc
A chemical property is one that tells us what a substance can do with regards to whether or not the substance reacts with other substances.
Examples are flammability, rusting of iron, precipitation, decomposition of water etc.
