Answer:
About 7.9 L.
Explanation:
We can utilize the ideal gas law. Recall that:

Because the amount of carbon dioxide does not change, we can rearrange to formula to:

Because the right-hand side stays constant, we have that:

Hence substitute initial values and known final values:

Therefore, the final volume is about 7.9 L.
Answer:
im pretty sure its A, if not so sorry!!
Explanation:
Small area or region with a relatively hot temperature in comparison to its surroundings.a very hot and dry place where a fire is likely to start, or where a fire has been burning.
Answer: B
Explanation: Graph B compares the two temperatures on separate lines so that we can see the comoparison directly, as a function of time. Not only does the graph quickly answer which condition id most favorable to colony growth, but it also hints at some behaviors that may accelerate growth as time goes on. Graph C is a possible answer, if the <u>only</u> question is which promotes growth the fastest. But the questions asks "compare," which Graph B does not allow as well as Graph C.
17) 8.4 / 20 x 100
18) 20 . 0.5150
19) 6,50% because (as you said) the law of definite proportions states that regardless of the amount, a compound is always composed of the same elements in the same proportion by mass
