Explanation:
We know that:
1 atm = 760 mm of Hg (Standardly)
Multiply both sides by 2.27
2.27 atm = 760 * 2.27 mm of Hg
2.27 atm = 1,725 mm of Hg

Explain the process of ionization in at least 1 paragraph.
Brainliest goes to best explanation!
Answers
Explanation:
Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.
What is surface tension and why is it important?
Answers
Answer:
What is surface tension?
Explanation:
Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer.
Surface tension forces between mucosal surfaces play an important role in the pathogenesis of the disease. The obstruction of upper airway elicit the activation of autonomic nervous system, hypoxemia, and arousal from sleep.

Carbon has three isotopes: carbon-12, carbon 13, and carbon-14. If the average atomic mass on the
periodic table for carbon is 12.011 amu, which isotope is most abundant? Explain your answer using a complete sentence.
Answers
Answer
The most abundant carbon isotope is carbon-12
Explanation:
The relative atomic mass of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass of carbon.
In fact, the C-12 isotope makes up 98.9% of carbon atoms, C-13 makes up 1.1% of carbon atoms, and C-14 makes up just a trace of carbon atoms as they are found in nature.

On vacation, Aria went scuba diving in the Pacific Ocean for the very first time. She rose toward the surface of the water at a steady speed for 4 minutes. She rose 36 meters in that time. What was her speed? HELP ME ASAP!!!!!!!!!!!!!
Answers
Aria speed during scuba diving was 0.15 m/s.
Speed is the ratio of the distance travelled to the time taken. Speed is given by:
Speed = distance / time
Given that the distance travelled was 36 meters and the time was 4 minutes, hence:
Time = 4 minutes × 60 seconds per minute = 240 seconds
Speed = 36 m / 240 s
Speed = 0.15 m/s
Therefore Aria speed during scuba diving was 0.15 m/s.

A boy rides his bike to his friend's house. He travels 2 miles in 8 minutes, the boy's average speed will be 0.25 meters per second (m/s).
What is speed?Speed of any object is the rate of change of position in the given time of interval or given time of the unit is said to be speed an can be measured by dividing the distance traveled with the time.
A boy rides his bike to his friend's house. He travels 2 miles in 8 minutes so the speed will be,
Speed = distance / time
Speed = 2 miles / 8 minutes
Sped = 0.25 meter per second (m/s)
Therefore, the average speed will be 0.25 meters per second (m/s) if the boy rides his bike to his friend's house. He travels 2 miles in 8 minutes.

Answers
The Elephant Maximus is the species that was introduced and later became extinct on Maguindanao.
Extinction occurs as all members of a species die, and therefore the species disappears. This includes complete extinction or extinction of the species in a specific zone.
In the case of the Elephant Maximus, which is known as the Asian Elephant, this species became extinct in a region known as Maguindanao in the Philippines.
This partial extinction occurred as the elephants from this zone were taken to Sabah in Malaysia from the 13th century to the 16th century. This occurred because the Sultans of this region considered this elephant to be a valuable and even sacred animal.

Answers
Answer:
pour the rock salt mixture throught a filter made from paper and allow the liquid to filtrate .
Explanation:
Separating Sand and Salt
Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.
Pour the liquid through a paper filter made of rock salt mixture and let it filter, after complete filtration we obtain crystals of salt.
What is filtration?Filtration is defined as the technique of removing solid particles from a liquid or gaseous fluid by passing the fluid through a filter media while keeping the solid particles behind.
It can also be defined as a physical method that uses a filter media with a complicated structure that only allows fluid to pass through to separate solid matter and liquid from a combination.
There are six types of filtration.
