The mass number is the same as the number of neutrons
Answer:
He started factories and mills. He created World's first water- powered mill at Cromford, where he employed more than 200 people. This was just the beginning of the many factories which he would later set up. Because of this, Arkwright was known as the father of the modern industrial factory system........Hope you got it
Silver has one valence electron and oxygen has 6 electrons in the outermost shell. Ionic bonds are formed by the transfer of electrons from a metal to a non metal.
atoms are most stable when they complete their outermost shell and complete the octet. This is when their s and p subshells in the outermost shell are complete, eight electrons hence complete octet.
silver has one valence electron so to become stable it will lose that valence electron and transfer it to oxygen. Oxygen has 6 valence electrons so to become stable it needs 2 electrons to complete its octet.
One silver atom gives one electron each, since oxygen needs 2 electrons ,
2 silver atoms are needed to form an ionic bond.
Ag will become cation - Ag⁺ and Oxygen will become an anion - O²⁻
ionic bond is formed due to the electrostatic attraction between oppositely charged ions
ionic compound - Ag₂O
2 silver atoms needed for one oxygen
Answer:
<h2>The answer is 5.18 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 22.5 mL
density = 0.23 g/mL
We have
mass = 0.23 × 22.5 = 5.175
We have the final answer as
<h3>5.18 g</h3>
Hope this helps you
The presence of a large population of sludgeworms indicates water depleted of oxygen and a high level of organic pollution.
The sludgeworms Tubifex is harvested and sold as tropical fish food since it is common near sewer outlets and serves as a sign of water or organic pollution. Polychaetes are crucial in rearranging the silt on the ocean floor.
Organic contamination happens when too much organic material, such sewage or manure, gets into the water.
There will be more decomposers and sludgeworms in a pond as the organic content accumulates. These decomposers and sludgeworms develop quickly and consume a lot of oxygen as they do so.
Hence, Sludgeworms are a sign of an abundance of oxygen-depleted water and significant levels of organic pollutants.
