PLEASE HELP ME ASAPPAAP. A reaction requires 22.4 L of gas at STP. You have 45.0 L of gas at 100 kPa and 373 K. The gas constant is
8.31L kPamol K
Which statement is true?

Question 4 options:

You cannot tell given this information.

You do not have enough gas for the reaction to occur.

You will have an excess of gas and the reaction will occur.

You will have too much gas for the reaction to occur.

I NEED HEL!!!

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 ratio of the conjugate base to the acid required to attain the desired ph.
