Answer:
The correct answer is - C) a different number of neutrons per atom.
Explanation:
Isotopes of an element are the same element and same atomic number but with different atomic mass and physical properties. The difference in their atomic mass occurs due to isotopes of an element have a different number of neutrons per atom.
The number of protons and the numbers of electrons are the same in the isotopes but only change occurs in the numbers of the neutrons. In isotopes of uranium U-233, U-235, and U-238 have the same number of protons but a different number of neutrons per atom.
The sample of smoke described above can be described as a heterogeneous mixture. This type of mixture do not have uniform properties and composition. So, getting a certain small sample would not represent the whole mixture since it does not have uniform composition.
Reactants would be the answer I think
Density = mass/volume
We are given a mass (which I am assuming is in kilograms) and a volume. Divide to find density.
Density of Saturn = 5.69x10²⁶ kg / 8.01x10²³ m³
Density of Saturn = 710. kg/m³
The density of water is 1000 kg/m³, which is higher than the density of Saturn. Since Saturn has a lower density than water, theoretically, Saturn would float in a gigantic bathtub filled with water.

Answer:</h3>
Density: 710. kg/m³
Float? Yes.
Answer:
B. Mixture
because air,sea water and alloy are example of Mixture
