Answer:
Reducing sugars are absent
Explanation:
Benedict's solution is an substance used in testing sugars. It is mixture of sodium carbonate, sodium citrate and copper(II) sulfate pentahydrate. It can be used instead of Fehling's solution in testing for the presence of reducing sugars.
Reducing sugars contain the -CHO group. If there is no colour change after the addition of Benedict's solution, then we can conclude that reducing sugars are absent.
The reaction ratio of hydrogen to the ammonia produced is 3:2 hence if 3 moles of hydrogen produce 2 moles of ammonia thus mathematically,
3moleH2=2mole NH3
5moleH2=?
Thus cross-multiplying
(5*2)/3= 3⅓ moles.
Answer: Hematocrit and WBC counts increases.
Explanation:
The hematocrit, also known as the "Hct", "crit" or PCV (packed cell volume) determines the percentage of red blood cells in the plasma. The term hematocrit means "to separate blood."
A patient with a severe burn loses huge amounts of plasma from damaged capillaries. As a result, the vascular space loses fluid in relation to cellular elements and the patient's hematocrit will be significantly increased.
Every substance has its own melting point therefore by finding the melting point we can be able to identify the substance
Answer:
Because photosynthesis ceases due to the lack of sunlight.
Explanation:
Plants typically absorb CO2 and release oxygen, but they also “exhale” CO2, particularly at night, when photosynthesis ceases due to the lack of sunlight. Forests also emit more CO2 when they are stressed by increasing temperatures.
