Answer:
Q = 6688 J
Explanation:
Given data:
Energy absorbed = ?
Mass of water = 80 g
Initial temperature = 40°C
Final temperature = 60°C
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
specific heat capacity of water 4.18 j/g.°C
ΔT = 60°C - 40°C
ΔT = 20°C
Q = 80 g ×4.18 j/g.°C × 20°C
Q = 6688 J
Answer:
Polysaccharide.
Explanation:
Biomolecules are the important chemical compounds present in living organisms that plays an important role to maintain life. Four different molecules are carbohydrates, fats, proteins and nucleotides.
Glucose is the hexose sugar made of carbon, hydrogen and oxygen with six carbon atoms. The glucose forms the monomers of carbohydrates. If large amount of glucose molecules combine together they will form the polysaccharides that leads to the carbohydrate formation.
Thus, the correct answer is polysaccharide.
Answer
there is 2 electrons on that atoms
