Answer:
There are alot of facts but here are a few
Explanation:
Atoms:
There are 3 parts to an atom
Protons have a positive electrical charge
Atoms are the smallest particles to make an element
Elements:
Hydrogen is the most common element in the world
An element is a substance that is made entirely from one type of atom.
An element is a substance that cannot be broken down into any other substance.
H₃O⁺ = ×
OH = ×
pH = 2.22
pOH = 11.78
<h3>What is pH?</h3>
The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.
The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.
⇒pH = -log()
Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.

Answer:
100 degrees, -41 degrees Celcius, and -24 celcius
Explanation:
Answer:
The pressure at 179 K is 21.8 kiloPascal.
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the nitrogen gas.
are the final pressure and temperature of the nitrogen gas.
We are given:
Putting values in above equation, we get:
The pressure at 179 K is 21.8 kiloPascal.
