Explanation:
1 gallon equals 3,785 liters.
How many liters are in 30 gallons?
We apply a simple rule of three to solve it
Answer: I think it is: 113.5624 Liters of gas
Explanation:
b. Cold winter day:
Answer:
They get flat and start to deflate
Explanation:
Answer:
27·92 %
Explanation:
Given chemical equation is
2C4H10 + 13O2 -----> 8CO2 + 10H2O
So according to the above balanced chemical equation for 2 moles of C4H10, 10 moles of water is produced
Molecular weight of C4H10 is 58 g
Molecular weight of water is 18 g
So for 116 g of C4H10, 180 g of water is produced and therefore for 1 g of C4H10 (180 ÷ 116) g of water is produced
∴ For 1 g of C4H10 1·552 g of water is produced
For 3000 g of C4H10, (3000 × 1·552) g of water is produced
∴ Number of grams of water produced for 3000 g of C4H10 is 4656 g
Percent yield =((experimental amount) ÷ (theoretical amount)) × 100
Here experimental amount is 4656 g
theoretical amount is 1300 g
∴ Percent yield = (1300 ÷ 4656) × 100 = 27·92 %
∴ Percent yield = 27·92 %

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.
Using two to three sentences, summarize what you investigated and observed in this lab.
Astronomers use a wide variety of technology to explore space and the electromagnetic spectrum; why do you believe it is essential to use many types of equipment when studying space?
If carbon was the most common element found in the moons and planets, what element is missing that would make them similar to Earth? Explain why. (Hint: Think about the carbon cycle.)
We know that the electromagnetic spectrum uses wavelengths and frequencies to determine a lot about outer space. How does it help us find out the make-up of stars?
Why might it be useful to determine the elements that a planet or moon is made up of?
