What would happen if you poured gasoline into water? * the gasoline would float on top of the water
the water would float on top of the gasoline
the gasoline would be suspended in the middle of the water
the water would be suspended in the middle of the gasoline

The answer is: A - the gasoline would float on top of the water.

Explanation:

Due to the difference in density of water and fuel, mixing cannot occur. As soon as gasoline is added to water, it will remain on top because water is denser than fuel.

You would get the same effect if you mix oil and water together.

Using the information given in the diagram, the number of protons, neutrons and electrons in an atom of the Fluorine-19 sample are 9, 10 and 9 respectively.

Given :

Atomic number = 9Atomic mass = 19

The number of protons = Atomic number

Hence, the number of protons = 9

2).

Recall :

Atomic mass = proton number + neutron number

Substituting the values into the formula :

19 = 9 + neutron number

neutron number = 19 - 9

neutron number = 10

3.)

The number of electrons = proton number + charge

Since, the atom contains neutral atom, then charge = 0

Number of electrons = 9 + 0

Number of electrons = 9

Therefore, the Number of protons, neutrons and electrons are 9, 10 and 9 respectively.
