What is the concentration of a dextrose solution prepared by diluting 15 mL of a 1.0 M dextrose solution to 25 mL using a 25 mL volumetric flask

C₂ = 0.60 M

Explanation:

Step 1: Given data

Step 2: Calculate the concentration of the diluted dextrose solution

We will use the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 1.0 M × 15 mL / 25 mL

C₂ = 0.60 M

i believe it is c.) 1575 j.

  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-
