Answer:
Scientists use a geologic time scale to illustrate the order in which events on Earth have happened.
Explanation:
Scientists can use the geologic time scale to determine the order in which several events on Earth have happened or taken place.
What is a geologic timescale?The geologic time scale can be described as a representation of time based on the rock record of Earth and is a system of chronological dating that uses chronostratigraphy and geochronology.
The geologic time scale can be used by scientists to observe changes in the fossils by examing the oldest to youngest sedimentary rocks or layer by layer.
The geologic timescale also used relative dating to divide Earth’s past into many layers of time and utilized absolute dating to know the actual number of years ago that specific occurrences took place.
Relative dating does not show any specific dates but it allows us to know if a fossil or stratigraphic layer is older than another while Absolute dating methods provide more specific origin dates and timelines.

Soap and bleach are both alkaline, or basic. Soap is safe to touch and use on skin. Bleach is toxic and is not safe to touch. Why is soap safe to touch but not bleach?
Soap is a weaker base than bleach. This means that soap has more hydronium ions than bleach. It is closer to a neutral pH.
Soap is a weaker base than bleach. This means that soap has more hydroxide ions than bleach. It is closer to a neutral pH.
Soap is a stronger base than bleach. This means that soap has more hydronium ions than bleach. It is closer to a neutral pH.
Soap is a stronger base than bleach. This means that soap has more hydroxide ions than bleach. It is closer to a neutral pH.
Answer:
you can yes soap because the chemicals are safe in it
Explanation:
bleach you can not yes because but has wires cgemucaks than soap
Soap is a weaker base than bleach and it has more hydronium ions than bleach. It lies closer to a neutral pH. Therefore, option (A) is correct.
What are acids and bases?An acid is capable of donating a proton to another substance and is generally identified by its sour taste. A base is capable to accept a hydrogen ion from acid and is characterized by a bitter taste and a slippery texture.
Acids can turn blue litmus paper into red while Bases can turn red litmus paper into blue. A base can dissolve in water and when bases chemically react with acids, yield salt, and water as products.
pH = -log [H⁺]
The pH value of the bases lies between 7 to 14. The more the pH value stronger will be the base. The concentration of hydronium ions will be less if the pH value is higher. Therefore, soap has less pH value so it has more hydronium ions.
