635 mL of a gas is at a pressure of 8.00 atm. What is the volume of the gas at standard pressure (1 atm) (STP)? (Boyle)

Explanation:

The volume of the gas at standard pressure can be found by using the formula for Boyle's law which is

Since we are finding the new volume

From the question we have

We have the final answer as

Hope this helps you

the answer is a. co2, this would be colder than the : )

explanation:

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.
