Answer:
The pH of the solution is 1.34, being an acidic pH.
Explanation:
pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
The acronym pH stands for hydrogen potential.
The pH scale ranges from 0 to 14. Values less than 7 indicate the acidity range and those greater than 7 indicate alkalinity or basicity. Value 7 is considered neutral. Mathematically, pH is the negative logarithm of the molar concentration of hydrogen or proton ions (H⁺) or hydronium ions (H₃O⁺).
pH= - log [H⁺] = - log [H₃O⁺]
In this case, [H⁺]= 4.6*10⁻² M. Replacing:
pH= - log 4.6*10⁻²
Solving:
pH= 1.34

An adaptation is a physical or behavioral feature that helps an animal stay alive.
1. An adaptation an animal needs to meet the need for food: Sharp teeth.
An adaptation to meet the need for water: A tongue.
An adaptation for shelter: Sharp claws to climb trees for shelter.
3. Starts storing more fat, bears a warmer coat, and sleeps for hibernation.
5. If it's cold outside, fur can help keep an animal warm. A chameleon uses his skin (or covering) to blend into this surroundings.
6. "A". Sharp eyesight.

Answer:
Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it.
The answer would be c. Have you ever seen gravy? It always separates and leaves different layers.
Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.
Hope this helps!
