Answer:

1s2 2s2 2p6 3s2 3p6

Explanation:

Calcium is the 20th element. It has 20 electrons in it's neutral state. The electronic configuration is given as;

1s2 2s2 2p6 3s2 3p6 4s2

However in the compound; calcium chloride, it does not exist in it's neutral state.

CaCl2 --> Ca2+ + Cl-

In Ca2+ state, it has lost two electrons, The total number of electrons becomes; 20 - 2 = 18 electrons.

The electronic configuration is given as;

1s2 2s2 2p6 3s2 3p6

Can a molecule with nonpolar bonds ever be polar? Why why not?

Tanya [424]

Answer:

A molecule that has only nonpolar bonds and no polar bonds cannot be polar.

Explanation:

However, a molecule that CONTAINS nonpolar bonds is different, because it can contain polar bonds. A molecule that contains nonpolar bonds can be polar as long as it also contains polar bonds.

4) A granola bar has a mass of 42.9 g and the granola bar contains 26.20% honey

nata0808 [166]

Answer:

The percentage of honey in one granola bar is 26.02 percent.

Explanation:

The weight of 1 granola bar is 42.9 grams. The grams of honey that is present in one granola bar is equal to 26.02 percent of 42.9 = 11.16 g

Now the amount of honey in the factory is given as 189.5g the weight of total granola bars would be

$= 42.9/11.16 x 189.5= 728.25$

So no. of granula bars $=728.25/42.9 =16.9$ that can be Approximated to nearly 17

Now if one box has 6 bars then 17 bars will have to fit inside three boxes
