The definition in Volume is a the amount of space a substance or object occupies, or that is enclosed within a container, especially when great. For example "The sewer could not cope with the volume of rainwater" . You can say it in different ways, such as capacity, size, magnitude, mass, bulk, extent and more. I hope this helps :-).
Answer:
The answer to your question is 42.9 g of Ca
Explanation:
Data
mass of Ca = ?
mass of N₂ = 10 g
Balanced chemical reaction
3Ca + N₂ ⇒ Ca₃N₂
Process
1.- Calculate the molar mass of the reactants.
Ca = 3(40) = 120 g
N₂ = 2(14) = 28 g
2.- Calculate the mass of Calcium using proportions and the molar mass of the reactants.
120 g of Ca ---------------- 28 g of N₂
x ---------------- 10 g of N₂
x = (10 x 120) / 28
x = 1200 / 28
x = 42.9 g of Ca
Al species is oxidized in the reaction below al2o3(s) 3 co(g) → 2 al(s) 3 co2(g by oxidation
The reaction brought on by coming into touch with oxygen molecules is known as oxidation. These materials can be non-metals like live tissues or metals. Technically speaking, oxidation is the loss of one electron during the phase of interaction between two or more atoms.
Initially, the word "oxidation" was used to refer to chemical processes in which an element reacts with oxygen. An illustration of this is the oxidation of magnesium in the formation of magnesium oxide when magnesium metal and oxygen react.
The biological oxygen demand (BOD) of wastewater is decreased after oxidation, which also lessens some contaminants' toxicity. Some contaminants undergo this treatment and are transformed into carbon dioxide, water, and biosolids. Disinfection is commonly accomplished using chemical oxidation.

uuuuuuuuuuuuuuuuuuuuuuum i think it the way its shaped
Two moles because one moles would be 6.02×10 23 atoms 2 moles would equal twice that number of atoms
