The product of the measurements 2.05 cm x 32 cm should be rounded to1 significant figure2 significant figure3 significant figure5 significant figure

Two significant figures

Step-by-step explanation:

In multiplication problems, your answer can have no more significant figures than the number with the fewest significant figures.

2.05 cm × 32 cm = 65.600 000 00 cm² (by my calculator)

There are three significant figures in 2.05, but only two in 32.

You must round to two significant figures and report the answer as 66 cm².

65.600 000 00 cm² ⟶ 66 cm²  

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
