Answer:
Repeat the experiment several times to make sure the results are reliable.
Explanation:
The best way for Chris to validate his results is to repeat the experiment several times to make sure the results are reliable.
For a hypothesis to be accepted it must be testable.
- The more standard data points obtained from an experiment, the more the reliability index increases.
- Chris should not just conclude with one data point.
- In fact, most scientist prefers to use up to 30 data points before reliability can be assumed.
- So, Chris should repeat the experiment as much as possible to make sure the results are reliable.
D. Matter is anything that is made of organic substances and is found on the earth.
Answer:
Explanation:
7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C
= 2.1 g of C .
This will be contained in 3.256 g of isopentyl acetate
3.156 g of H₂O will contain 2 x 3.156 / 18 g of H
= .351 g of H
This will be contained in 3.256 g of isopentyl acetate
Rest will be oxygen
amount of oxygen in 3.256 g of isopentyl acetate
= 3.256 - ( 2.1 + .351 )
= .805 g
ratio of C , H , O in isopentyl acetate
= 2.1 g : .351 g : .805 g
2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles
= .175 : .351 : .05 ratio of moles
= 3.5 : 7.02: 1
= 7 : 14 : 2
empirical formula of isopentyl acetate
= C₇ H₁₄ O₂ .
