An object has a mass of 95 grams and a density of 1.7 g/ml. find the volume of the object.

The formula is density = mass / Volume

density = 1.7 g/mL

mass = 95 grams

Volume = ?

1.7 g/mL = 95 g / Volume

Volume = 95 g / 1.7 g/mL

Volume = 55.88 mL

Hope this help!

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.

increased stability in the completion of fluorine's outer shell.
