Convert 145.0 mm to meters and express the answer to the correct number of significant digits.
a. 0.1450 m
b. 0.145 m
c. 145,000 m
d. 1.450 m

145.0 mm = 0.01450 m

Explanation:

We know that :

1 mm = 0.001 meters

the unit factor will be:

Thus to convert 145 mm we will convert it into meters by using the unit factor.

The significant figures in question is four.

So we will also report the answer to four significant figures.

Thus 145.0 mm = 0.01450 m

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
