Answer:
78.15 g
Explanation:
Number of moles of C₇H₆O₃ that reacted = mass/molar mass = 57.6g/126 gmol-1
Number of moles of C₇H₆O₃ = 0.457 moles of C₇H₆O₃
From the reaction equation;
1 mole of C₇H₆O₃ yields one mole of aspirin
0.457 moles of C₇H₆O₃ yields C₇H₆O₃ of aspirin
Hence theoretical yield of aspirin = 0.457 moles × 180 gmol-1 = 82.26g of aspirin
% yield = actual yield/theoretical yield ×100
Actual yield= % yield × theoretical yield/100
Actual yield = 95.0 × 82.26/100
Actual yield = 78.15 g
When placed in an electrical field, the negative charge found in the sugar-phosphate backbone of DNA polymers cause them to migrate towards the positive electrode.
<span>In gel electrophoresis, electricity is used to separate fragments of DNA based on its length. DNA is place in a porous gel. The pores of the gel restricts the movement of the DNA. It then creates fragments on the DNA because its movement varies on its lengths. </span>
According to law of conservation of matter and energy, amount of both of them will remain same
The anode is zinc, and the cathode is the nail
Answer:
Hyperglycemia, or high blood glucose, is a symptom that characterizes diabetes. Insufficient insulin production, resistance to the actions of insulin, or both can cause diabetes to develop. When a person eats carbohydrates, the body breaks them down into simple sugars that enter the bloodstream
