Please help me with this test, thank you:)

1. Suppose you had 40 liters of methane gas at STP. If the temperature increased by 35 degrees C, what would the new volume of gas become?
ANSWER:

2. Sherry had 13.5 liters of oxygen gas measured at 25 degrees Celsius. She took the container that was holding the gas outdoors where the temperature was 10 degrees Celsius. What would the volume of the gas be after it cooled?
ANSWER:

3. Francisco had 46 liters of hydrogen gas at 37 degrees Celsius. If he changed the environment of the room to reflect STP conditions, what would the new volume of the hydrogen be?
ANSWER:

4. Hydrogen carbonate will decompose to produce water and carbon dioxide. Suppose you began with 45 grams of hydrogen carbonate, how many liters of carbon dioxide could you produce from this reaction assuming the reaction took place at STP?
ANSWER:

5. If the carbon dioxide produced in question 4 was heated to 30 degrees C, what would the new volume of CO2 be?
ANSWER:

6. Carbon monoxide gas (CO) and oxygen gas will combine to produce carbon dioxide gas (CO2). IF you begin with 5 liters of carbon monoxide, how many liters f carbon dioxide can you produce from this reaction? Assume you conduct this reaction at STP.
ANSWER:

7. If the carbon dioxide gas you produced from the reaction in question 6 was heated to 200 degrees C, what would the new volume of gas be?
ANSWER:

8. Shorty had 1 liter of 3M hydrogen sulfate. If he added aluminum to this solution until the reaction stopped, how many liters of hydrogen gas could he produce from the reaction? Aluminum sulfate is a byproduct of the reaction. Assume the reaction took place at STP.
