This data was collected after conducting an experiment about the amount, in liters, of water a specific plant needs per month. An accepted value for the measurement is 6 liters. These are the collected experimental values. Which values in the collected data are precise? Check all that apply.

all of them

Explanation:

preciseness is measured by how many decimal places are used not by accuracy. since all of these are to the same decimal place they are all equally precise even if they are inaccurate.

  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-
