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.

The given statement is True.
This is single replacement reaction.
As reactivity decreases down the group,
Iodine is less reactive than Chlorine.
And so Iodine cannot replace chlorine from FeCl2.
I2 + FeCl2 ---> no reaction (Iodine is less reactive than chlorine)
You need to do something like that your self so sorry can help.
Answer:
1.8 × 10⁻⁴ mol M/s
Explanation:
Step 1: Write the balanced reaction
2 Br⁻ ⇒ Br₂
Step 2: Establish the appropriate molar ratio
The molar ratio of Br⁻ to Br₂ is 2:1.
Step 3: Calculate the rate of appearance of Br₂
The rate of disappearance of Br⁻ at some moment in time was determined to be 3.5 × 10⁻⁴ M/s. The rate of appearance of Br₂ is:
3.5 × 10⁻⁴ mol Br⁻/L.s × (1 mol Br₂/2 mol Br⁻) = 1.8 × 10⁻⁴ mol Br₂/L.s
