The answer is System.
When a scientific investigation is in progress, its used to perform and understand the natural phenomenon that goes on using the scientific method. Since this is a descriptive investigation, it provides a descriptive account of any system by looking at it without any prior knowledge to that subject. This method of investigation does not use a hypothesis. Thus, proves our answer correct.
Best of Luck!
Yes they are a pure substance
1.5 moles of gas
Reaction of Al with to form is given below...
2 Al + 1.5 →
Here, 2 moles of Aluminum reacts with 1.5 moles of
atomic weight of aluminum = 27 g / mole
so, 1 mole of aluminum contains 27 g
then how many moles are there if it has 54 g in it.
moles of aluminum in 54 g = 54/27 = 2 moles
As per the equation mentioned above,
2 moles of aluminum reacts with 1.5 moles of .
∴1.5 moles of oxygen gas (02) are needed to completely react with 54.0 g of aluminum.

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:
I think they are beneficial for the life of those symbiotic organisms that require yes or yes from another to be able to live.
Although an ecosystem could not be carried out if only this relationship would occur, since symbiotic relationships we have an organism where it needs another to live and even removes the necessary nutrients for it, that is why the chain should continue with other types of relationships .
Explanation:
The symbiosis is defined as "Intimate association of organisms of different species to mutually benefit in their vital development" that is why adequate coexistence between these living organisms is needed, otherwise this phenomenon would not occur.
A very good example of the symbiosis is: Bees and plants where the bee is the pollinating agent of the plant so that it continues to reproduce and the plant is the bee's food source.
Therefore I believe that the development of this type of relationship is VITAL, and very fundamental, otherwise I do not know if an ecosystem or a balanced ecosystem could be carried out.
