The prefix 'mili'- means a thousandth. so a mili-liter is a thousandth of a liter. 1 mililiter= 1/1000 liter, how many liters is 1,939 mililiters? round your answer to the nearest tenth of a liter.

- .

Solution:- It is correct that mili means a thousandth that is part. We have been given with 1939 mililiters and asked to convert it to liters and round the answer to the nearest tenth of a liter. We do this conversion by using dimensional analysis, a good of showing unit conversions. The set is as shown below:

=

Now, we round this to the nearest tenth and it becomes .

So, 1939 mililiters equals to 2.0 liters.

  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-

the answer is barium and copper bromide
