Answer:
b) +2 and +3.
Explanation:
Hello,
In this case, given the molecular formulas:
And:
We can relate the subscripts with the oxidation states by knowing that they are crossed when the compound is formed, for that reason, we notice that oxygen oxidation state should be -2 for both cases and the oxidation state of X in the first formula must be +2 since both X and O has one as their subscript as they were simplified:
Moreover, for the second case the oxidation state of X should be +3 in order to obtain 3 as the subscript of oxygen:
Thus, answer is b)+2 and +3
Best regards.
Explanation :
Barfoed's test : Monosaccharides and reducing disaccharides can be distinguish by this test. The test solution is prepared by dissolving copper (II) acetate in acetic acid.
The equation for the oxidation of glucose by CuO is:
(1)
(2)
Here, CuO act as a catalyst.
In this reaction, first CuO salt get oxidized to form and then get reduced to back (CuO).
Hence, the equations are written above.

Answer: Heat
Explanation:
when there is enough air in the balloon that is when the crew would blast the burner into the envelope mouth building the pressure until the balloon inflates until it starts to lift off the ground and as the air builds up the balloon will lift right off the ground
