Answer from: ultimatesaiyan

Hey there!

There are many gases in the atmosphere - like greenhouse gases such as methane and carbon dioxide that lead to climate change, and water vapor and oxygen that help us. However, there's only one element that remains abundant throughout the entirety of the atmosphere, and that element is nitrogen. Nitrogen takes up nearly 78% of the atmosphere and leads in the composition of the atmosphere over an astounding 21% oxygen.

Hope this helps!

Answer from: Quest

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

Answer from: Quest

the balanced equation for reaction of ca metal with o2 to produce cao is as below

2 ca+ o2→ 2 cao2

explanation

the reaction is balanced since the number of atoms in reactant side is equal to number of atoms in product side. for example they are 2 atom of ca in reactant side and 2 atoms of ca in the product side.

the process is a meet the requirement of redox reaction because : calcium is oxidized from oxidation state 0 to 2+ while oxygen is reduced from oxidation state 0 to 2-
