Geologists divide Earth’s long history into smaller units that make up the geologic time scale.
aleksandrvk [35]

False

Explanation:

The geologic time scale which simplifies earth's long history is broad division of deep time. It consists of a large and small divisions.

  • The geologic time scale is divided into large broad categories; called eons, eras, period and epoch.
  • The scale is merges absolute dating of events that has happened in geologic past and their relative ages.
  • Broad categories on the scale are further simplified into smaller units.
  • Relative age puts events in the order of their appearance using a couple of geologic principles.

A carpet sells for $28.99 a square yard. What is the price of the carpet per square meter?
9966 [12]

It is given that the price of the carpet is $ 28.99 per square yard

Step 1: Convert square yard to square meter

1 square yard = 0.836 square meter

Step 2: Calculate the cost/square meter

Now based on the relation in step (1) we can write

0.836 square meter of carpet costs $ 28.99

Therefore the cost of 1 square meter of the carpet would be

= $ 28.99 * 1 sq meter/0.836 sq meter

= $ 34.68

GalinKa [24]

Answer:

SeCl₆ < SeF₂ < SeO₂

Explanation:

(A) SeO₂

The central atom has 2 bond pairs and 1 lone pair. The molecule is bent shaped which has an angle of 120°.

(B) SeCl₆

The central atom has 6 bond pairs and 0 lone pair. The geometry is octahedral in which the equatorial bonds has an angle of 90° and axial bond has an angle of 90°.

(C) SeF₂

The central atom has 2 bond pairs and 2 lone pairs. The geometry is bent shape which has an angle of approximately 105.5°.

The order is:

<u>SeCl₆ < SeF₂ < SeO₂</u>
