adoni [48]

Answer:

36.09% is the mass percent composition of calcium in calcium chloride

Explanation:

Mass percent is defined as one hundred times the ratio between the mass of a compound (In this case, Calcium), and the total mass of the sample:

<em>Mass Percent = Mass compound / Total mass of the sample × 100</em>

<em />

Computing the values of the problem:

Mass Percent = 0.690g / 1.912g * 100

Mass percent =

Which of the following is NOT true regarding Rutherford's Gold Foil experiment?
erastova [34]

Answer:

The area around the nucleus must be of low mass.

Explanation:

Rutherford`s experiment showed that there are some positive charges in the center of the atoms, and because they are all together, they will give a great mass to the atom.

It was quite different from Thomson`s experiment, in which it was thought that the negative charges were mixed with the positive charges, around the atom (like a Pudding Model). In Rutherford`s experiment, because the direction of beta particles, it was the prediction of the positive nucleus.

Hope this info is useful.
