Answer:
The answer is D.
Explanation:
I learned about this last year. Its very simple if you let your parents or teachers explain it to you!
Answer: potassium iodide is the basic test for starch,and the positive test is blue-black coloration, any other test substance which is not starch will give a negative results.
Explanation:
Starch is an example of polysaccharide and since the standard test for it is potassium iodide solution, it gives a positive test.
Diasaccharides e.g maltose are reducing sugars.their standard test is BENEDICT test .
Therefore, in the hydrolysis; starch should give a positve test, while Diasaccharides should give negative rest.

3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K
IDEAL GAS LAW:
- The temperature of a gas can be calculated using the ideal gas law equation:
PV = nRT
Where;
- P = pressure (atm)
- V = volume (L)
- n = number of moles (mol)
- R = gas law constant (0.0821 Latm/molK)
- T = temperature (K)
- According to this question, P = 1.5atm, V = 2.7L, n = 3.5moles, T = ?
- 1.5 × 2.7 = 3.5 × 0.0821 × T
- Therefore, 3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K
