(a)
Interpretation:
Based on the densities given in table 1.1, among the elements, nickel, gold, lead and magnesium, the element that floats on liquid mercury at
Concept Introduction:
Buoyancy:
It explains the floating nature of a substance in a fluid based on the densities of the substance and the fluid in which it is placed.
If a substance with low density is placed in a fluid of more density, then the substance floats in that fluid.
If a substance with high density is placed in a fluid of low density, then the substance sinks in that fluid.
(b)
Interpretation:
Based on the densities given in table 1.1, among the elements, titanium, copper, iron and gold, the element that floats highest on mercury has to be given.
Concept Introduction:

- Don't used Ai solutionarrow_forward5. A solution of sucrose is fermented in a vessel until the evolution of CO2 ceases. Then, the product solution is analyzed and found to contain, 45% ethanol; 5% acetic acid; and 15% glycerin by weight. If the original charge is 500 kg, evaluate; e. The ratio of sucrose to water in the original charge (wt/wt). f. Moles of CO2 evolved. g. Maximum possible amount of ethanol that could be formed. h. Conversion efficiency. i. Per cent excess of excess reactant. Reactions: Inversion reaction: C12H22O11 + H2O →2C6H12O6 Fermentation reaction: C6H12O6 →→2C2H5OH + 2CO2 Formation of acetic acid and glycerin: C6H12O6 + C2H5OH + H₂O→ CH3COOH + 2C3H8O3arrow_forwardShow work. don't give Ai generated solution.
