Answer:

B) He

Step-by-step explanation:

This ion has gained 3 valence electrons, meaning it is a full octet or all 8 valence electrons in its outer most shell

The only atom there that is a noble gas or full octet is He or Helium

Answer:

7 boxes

Step-by-step explanation:

The area of a rectangular prism is given by the formula ...

A = 2(LW +H(L+W))

The amount of wallpaper Carmen needs for one box is found by computing the area of the box.

A = 2(5·6 +7(5+6)) = 2(30 +7·11) = 2(107) = 214 . . . square feet

<h3>All boxes</h3>

Carmen will be using a total of 214x square feet of wallpaper to cover x boxes. She has 1498 ft² available, so can cover ...

1498 ft²/(214 ft²/box) = 7 boxes

Carmen has enough wallpaper to cover 7 storage boxes.
