Convert to standard notation. 1.312 x 10^2

The answer would be 131.2

Explanation: How I got my answer is quite simple. In order for it to turn into standard notation, it would need to be turned into the answer of an equation. The equation here would be "1.312 x 10^2". 10^2 would be 100. Multiply 100 by 1.312 will make the decimal point move 2 times to the right, so it will end up in front of the 2. That would make the answer 131.2

I hope this info helps! :P

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
