Answer: The size of actual bed is 75 inches

Explanation: Scale refers to the ratio of the original dimension to the dimension on paper (miniaturised dimension). Since it is a ratio, it has no dimension.

Scale= original dimension/miniaturised dimension

Given that scale is 1:25

It means that every 1 inch on paper would correspond to 25 inches in reality.

The length of the model bed= 3 inches

Hence, the length of the original bed is 25*3 = 75 inches

Draw a Lewis structure for SF4 that has minimized formal charges. Include all nonbonding electrons and any nonzero formal charge

gayaneshka [121]

Answer:

See explanation and image attached

Explanation:

The compound SF4 is sulphur tetraflouride. It has a zero formal charge and has a total of 34 valence electrons.

The central atom in the molecule is sulphur in an sp3d hybridization state hence the molecule has a trigonal bipyramidal electron geometry. Since it is a molecule of the sort AX4E; it gives a see-saw molecular shape.

The structure of the molecule is shown in the image attached to this answer.
