The energy increases because the molecules in water move faster
Answer:
86
Explanation:
The reaction that takes place is:
- C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
First we <u>convert moles of ethanol to moles of water</u>:
- 1.6 mol ethanol * = 4.8 mol H₂O
Then we <u>convert moles of water to grams of water</u>, using its molar mass:
- 4.8 mol H₂O * 18 g/mol = 86.4 g
So 84.6 grams of water will be produced.
Answer and explanation:
1. To increases the accuracy of the measurement, the person should try to make sure the ruler is parallel to the object they are measuring. If they measure the object with the ruler not being parallel the measurement will end up larger then expected. To increase the precision the person must measure with the ruler in the same position each time.
2. A situation in which a set of measurements are precise but not accurate could be if a student measured an object at an incorrect angle many times, like the inaccurate measuring in the image above. All of the measurements would be inaccurate, but since they were all measured inaccuratly the same way, they will be precise.
3. An objects mass is defined as being the amount of matter in said object. An objects weight is defined as being the force exerted on an object by gravity. Although the man would weigh less on the Moon because there is less gravity, he still would not fit in his clothes because his mass has not changed.
The answers is 3 because the secon C was changed to a G.
1 and 2 are incorrect because you do not have the same number of bases as the original sequence. 3 a base was change to the U, which appears in RNA not DNA.
Answer:
C
Explanation:
For an organism scientific names the first part is the genus and the second is the species
