Use the scenario to answer the question Someone purchases a disposable water bottle, uses it several times, then throws it in the garbage
How would you evaluate these actions in terms of conservation?

O It is better than using a glass to drink water from the tap, but they should recycle the bottle.

O It is better than using the bottle only once, but they should recycle the bottle.

It is better than using a glass to drink water from the tap, but they should not be drinking so much water

O It is better than reusing it only once, but they should not be drinking so much water.

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.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

did anyone actually do this? like if anyone has submitted this i rly need .
