The area of the base is
Ab = 2.1 cm x 5.6 cm
The least number of significant figures is 2, so the number of significant figures of the product must also be 2.
Ab = 11.76 cm² which must be rounded-off to 12 cm²<span />
Answer:
1.Therefore ethanol has : 2 mols of carbon, 1 mole of oxygen and 6 mols of hydrogen. The requested mass percents are: 52.14% ; 34.77% ; 13.15%.
2. You should get 14.007(2) which is 28.014
3. I have no idear
4.idk
5. im sorry man this is too hard
Explanation:
Answer: 8.57 ml of KOH is required to reach the equivalence point.
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
Thus 8.57 ml of KOH is required to reach the equivalence point.
I think the highest theoretical temperature would be 36.5°C.
Hope I helped, sorry if not.
The particles will spread out more, and have more space between them
