Calculate the Molar Mass of Sodium Chloride, NaCl (g/mol).
Be sure to round your answer to the nearest hundredths (two decimal places).
Atomic Mass of Sodium (Na): 22.99
Atomic Mass of Chlorine (CI): 35.45

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

pure substance: iron,copper

impure substance: water,charcoal

where's the diagram?

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.
