a sample of carbon monoxide at 61°c under 0.73 atm of pressure takes up 88.2L of space. what mass of carbon monoxide is present in the sample?​

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.

answer; natural resources;

the correct answer would be b) volume versus temperature, because they are also directly proportional.
