Answer:
The molar mass and molecular weight of 3CaCl2 is 332.952.
I would pick "<span>Unsaturated hydrocarbons are very reactive." This is because while unsaturated hydrocarbons are indeed more reactive than their saturated counterparts, they still do require some energy, called activation energy, to be overcome before the reactions occur.</span>
The accepted model of an atom was made by Schrodinger, which is known as the quantum mechanical model. Unlike Bohr's model, electrons are represented as a cloud and not small balls orbiting the nucleus. There is no define path of electrons in Schrodinger's model, but it can predict the odds of where an electron is located.
The answer to your question is then Electrons form a cloud around the nucleus.

Ralph: "I'm not sure about bananas. I'd have to think about it."
Explanation:
To determine how many protons are present, simply know or use the following equation
X = number of protons
Y = number of electrons
Z = formal charge of the element
X - Y = Z = 0 for a neutral atom
X - Y = 2
Then to solve for x
X = Y + 2.
This means that we would need an additional 2 more protons than electrons.
