Answer:
Explanation:
Hello there!
In this case, since the vaporization process is carried out in order to turn a liquid into a gas due to the addition of heat, we can use the following heat equation involving the heat of vaporization of water or any other substance:
Thus, since this heat of vaporization for water is 2259.36 J/g, we plug in this amount to obtain the total energy for this process.
Which is positive due to the necessity of heat.

Number of moles = number of atoms/Avogadro's number
= (4.8x10^25)/(6.02x10^23)
=79.7 mol (3sf)
Answer:
1. 0.05moles of H₂O₂ is consumed in the reaction
2. the number of unreactive H₂O₂ is 0.20 moles
3. the percentage of H₂O₂ is 0.18%
4. no, not similar to 3% H₂O₂
5. percentage error = 0.94 = 94%
Explanation:
Answer: 2.7 centimeters long.
Explanation: count from starting at the beginning of the number on the ruler "2" and counted up until the end of the blue object. Counted 7 lines, so, 2.7 is the correct answer.
