As per the details given, 48.6 g are present in 0.885 moles of manganese. The correct option is A.
To determine the gram contained in a given number of moles, use the element's molar mass. Manganese (Mn) has a molar mass of roughly 54.94 g/mol.
To calculate the grammes in 0.885 moles of manganese, use the following formula:
moles of Mn × molar mass of Mn = mass of Mn in grams
On calculating it:
0.885 moles × 54.94 g/mol = 48.60 g
Therefore, the mass of manganese present in 0.885 moles of manganese is 48.60 grams.
Thus, the correct answer is A. 48.6g.

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!!!!!!!!!!!!!
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.

What is surface tension and why is it important?
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.
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.
How many grams of pure aluminum could be produced from 999 g of aluminum oxide?

1 mile equals 4 minutes
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.

Rock salt is a mixture of salt (sodium chloride) and sand. Describe how you would separate rock salt to obtain salt crystals and pure dry sand. In this question you get marks for how well your answer is written. You will get marks for: spelling, grammar, organising your ideas and information clearly and using key scientific words.
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.
Vacuum filtrationCentrifugal filtrationGravity filtrationCold filtrationHot filtrationMultilayer filtrationMixture is defined as a substance that is composed of two more chemical compounds or substances that do not chemically mix.
There are two types of mixture.

Explain the process of ionization in at least 1 paragraph.
Brainliest goes to best explanation!
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.
How do we find the atomic size of an atom?
Answer:
The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound. The covalent radius of a chlorine atom, for example, is half the distance between the nuclei of the atoms in a Cl2 molecule.

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.
