300 milliliter a of NaOH solution would contain of NaOH
Given volume percentage = Weight of solute =
Therefore, the answer is 300 ml.
crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
the balanced equation for reaction of ca metal with o2 to produce cao is as below
2 ca+ o2→ 2 cao2
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-
