How would you solve this problem??

Answers

Calculate the pOH where [OH⁻]=4.7×10⁻³M:
pOH=-log[OH⁻]
pOH=-log(4.7×10⁻³)
pOH=2.33

Calculate [OH⁻] if the pOH is 1.34:
pOH=-log[OH⁻]
10^(-pOH)=[OH⁻]
[OH⁻]=10^(-pOH)
[OH⁻]=10^(-1.34)
[OH-]=0.0457M or [OH⁻]=4.57×10⁻²M

Calculate pH if the [OH⁻] is 1.74×10⁻²M:
[H⁺]=K(w)/[OH⁻]              or                  pOH=-log[OH⁻]
[H⁺]=(1×10⁻¹⁴)/(1.57×10⁻²)                   pOH=-log(1.74×10⁻²)
[H⁺]=6.369×10⁻¹³M                              pOH=1.759
pH=-log[H⁺]                                          pH=14-pOH
pH=-log(6.369×10⁻¹³)                           pH=14-1.759
pH=12.2                                               pH=12.2

How to determine the charge of a polyatomic ion?

Answers

There are rules that needs to be followed.

The diagram below shows the sequence of events and processes which resulted in the origin of life on Earth.Picture shows a flow chart with a rectangle labeled non-living matter at the top, an oval labeled chemical processes below it, and a rectangle labeled A at the bottom.

Which of these events best fits the box labeled A?

A.destruction of cells
B.appearance of bacteria
C.creation of primitive plants
D.transformation of atmosphere

Answers

The rectangle A at the bottom will represent the appearance of bacteria as shown in the attached figure below. Therefore, option (B) is correct.

What is the origin of life on earth?

In biology, the origin of life can be described as the natural process by which life has arisen from non-living matter. The prevailing scientific hypothesis can be described as that the transition from non-living matter to living entities was not a single event.

An evolutionary process that can be involved in the formation of a habitable planet, is the prebiotic synthesis of organic molecules, molecular self-replication autocatalysis, and the emergence of cell membranes.

The study of abiogenesis or the origin of life objectives to determine how pre-life reactions gave origin to live under conditions different from those on Earth today. It uses tools from the fields of biology and chemistry, with recent approaches attempting a synthesis of many sciences.

Therefore, the flow charge will be like living matter → Chemical processes  → the appearance of bacteria.
